Portable Document Format PDF , standardized as ISO , is a file format developed by Adobe in to present documents , including text formatting and images, in a manner independent of application software , hardware , and operating systems. PDF files may contain a variety of content besides flat text and graphics including logical structuring elements, interactive elements such as annotations and form-fields, layers, rich media including video content , three-dimensional objects using U3D or PRC , and various other data formats.

The PDF specification also provides for encryption and digital signatures , file attachments, and metadata to enable workflows requiring these features. Adobe Systems made the PDF specification available free of charge in PDF was a proprietary format controlled by Adobe until it was released as an open standard on July 1, , and published by the International Organization for Standardization as ISO , [6] [7] at which time control of the specification passed to an ISO Committee of volunteer industry experts.

In , Adobe published a Public Patent License to ISO granting royalty-free rights for all patents owned by Adobe that are necessary to make, use, sell, and distribute PDF-compliant implementations. PDF 1. In December , the second edition of PDF 2. A PDF file is often a combination of vector graphics , text, and bitmap graphics.

The basic types of content in a PDF are. PostScript is a page description language run in an interpreter to generate an image, a process requiring many resources. It can handle graphics and standard features of programming languages such as if statements and loop commands. PDF is largely based on PostScript but simplified to remove flow control features like these, while graphics commands equivalent to lineto remain.

The graphics commands that are output by the PostScript code are collected and tokenized. Then, everything is compressed to a single file. Therefore, the entire PostScript world fonts, layout, measurements remains intact. Comments may contain 8-bit characters.

Objects may be either direct embedded in another object or indirect. Indirect objects are numbered with an object number and a generation number and defined between the obj and endobj keywords if residing in the document root. Beginning with PDF version 1. This technique enables non-stream objects to have standard stream filters applied to them, reduces the size of files that have large numbers of small indirect objects and is especially useful for Tagged PDF.

Object streams do not support specifying an object’s generation number other than 0. An index table, also called the cross-reference table, is located near the end of the file and gives the byte offset of each indirect object from the start of the file.

Before PDF version 1. Version 1. Such a stream may be used instead of the ASCII cross-reference table and contains the offsets and other information in binary format. If a cross-reference stream is not being used, the footer is preceded by the trailer keyword followed by a dictionary containing information that would otherwise be contained in the cross-reference stream object’s dictionary:.

Within each page, there are one or multiple content streams that describe the text, vector and images being drawn on the page. The content stream is stack-based , similar to PostScript. There are two layouts to the PDF files: non-linearized not “optimized” and linearized “optimized”. Non-linearized PDF files can be smaller than their linear counterparts, though they are slower to access because portions of the data required to assemble pages of the document are scattered throughout the PDF file.

Linearized PDF files also called “optimized” or “web optimized” PDF files are constructed in a manner that enables them to be read in a Web browser plugin without waiting for the entire file to download, since all objects required for the first page to display are optimally organized at the start of the file. The basic design of how graphics are represented in PDF is very similar to that of PostScript , except for the use of transparency , which was added in PDF 1.

PDF graphics use a device-independent Cartesian coordinate system to describe the surface of a page. A PDF page description can use a matrix to scale , rotate , or skew graphical elements. A key concept in PDF is that of the graphics state , which is a collection of graphical parameters that may be changed, saved, and restored by a page description. PDF has as of version 2. Paths can be stroked, filled, fill then stroked, or used for clipping.

Strokes and fills can use any color set in the graphics state, including patterns. PDF supports several types of patterns. The simplest is the tiling pattern in which a piece of artwork is specified to be drawn repeatedly. This may be a colored tiling pattern , with the colors specified in the pattern object, or an uncolored tiling pattern , which defers color specification to the time the pattern is drawn.

Beginning with PDF 1. There are seven types of shading patterns of which the simplest are the axial shading Type 2 and radial shading Type 3. The dictionary describes the properties of the image, and the stream contains the image data. Less commonly, small raster images may be embedded directly in a page description as an inline image. Images are typically filtered for compression purposes. Image filters supported in PDF include the following general-purpose filters:.

Normally all image content in a PDF is embedded in the file. But PDF allows image data to be stored in external files by the use of external streams or Alternate Images. Text in PDF is represented by text elements in page content streams. A text element specifies that characters should be drawn at certain positions. The characters are specified using the encoding of a selected font resource. A font object in PDF is a description of a digital typeface. It may either describe the characteristics of a typeface, or it may include an embedded font file.

The latter case is called an embedded font while the former is called an unembedded font. The font files that may be embedded are based on widely used standard digital font formats: Type 1 and its compressed variant CFF , TrueType , and beginning with PDF 1. Fourteen typefaces, known as the standard 14 fonts , have a special significance in PDF documents:.

These fonts are sometimes called the base fourteen fonts. Within text strings, characters are shown using character codes integers that map to glyphs in the current font using an encoding. There are several predefined encodings, including WinAnsi , MacRoman , and many encodings for East Asian languages and a font can have its own built-in encoding.

Although the WinAnsi and MacRoman encodings are derived from the historical properties of the Windows and Macintosh operating systems, fonts using these encodings work equally well on any platform. PDF can specify a predefined encoding to use, the font’s built-in encoding or provide a lookup table of differences to a predefined or built-in encoding not recommended with TrueType fonts.

For large fonts or fonts with non-standard glyphs, the special encodings Identity-H for horizontal writing and Identity-V for vertical are used. With such fonts, it is necessary to provide a ToUnicode table if semantic information about the characters is to be preserved.

The original imaging model of PDF was, like PostScript’s, opaque : each object drawn on the page completely replaced anything previously marked in the same location. In PDF 1. When transparency is used, new objects interact with previously marked objects to produce blending effects. The addition of transparency to PDF was done by means of new extensions that were designed to be ignored in products written to PDF 1.

As a result, files that use a small amount of transparency might view acceptably by older viewers, but files making extensive use of transparency could be viewed incorrectly by an older viewer. The transparency extensions are based on the key concepts of transparency groups , blending modes , shape , and alpha. The model is closely aligned with the features of Adobe Illustrator version 9. The blend modes were based on those used by Adobe Photoshop at the time.

When the PDF 1. They have since been published. The concept of a transparency group in PDF specification is independent of existing notions of “group” or “layer” in applications such as Adobe Illustrator. Those groupings reflect logical relationships among objects that are meaningful when editing those objects, but they are not part of the imaging model.

A “tagged” PDF see clause Technically speaking, tagged PDF is a stylized use of the format that builds on the logical structure framework introduced in PDF 1. Tagged PDF defines a set of standard structure types and attributes that allow page content text, graphics, and images to be extracted and reused for other purposes.

With the introduction of PDF version, 1. Layers, or as they are more formally known Optional Content Groups OCGs , refer to sections of content in a PDF document that can be selectively viewed or hidden by document authors or viewers.

This capability is useful in CAD drawings, layered artwork, maps, multi-language documents, etc. Basically, it consists of an Optional Content Properties Dictionary added to the document root.

This dictionary contains an array of Optional Content Groups OCGs , each describing a set of information and each of which may be individually displayed or suppressed, plus a set of Optional Content Configuration Dictionaries, which give the status Displayed or Suppressed of the given OCGs.

A PDF file may be encrypted , for security, in which case a password is needed to view or edit the contents. PDF 2. PDF files may be digitally signed, to provide secure authentication; complete details on implementing digital signatures in PDF is provided in ISO PDF files may also contain embedded DRM restrictions that provide further controls that limit copying, editing or printing.

These restrictions depend on the reader software to obey them, so the security they provide is limited. The standard security provided by PDF consists of two different methods and two different passwords: a user password , which encrypts the file and prevents opening, and an owner password , which specifies operations that should be restricted even when the document is decrypted, which can include modifying, printing, or copying text and graphics out of the document, or adding or modifying text notes and AcroForm fields.

The user password encrypts the file, while the owner password does not, instead relying on client software to respect these restrictions. An owner password can easily be removed by software, including some free online services. Even without removing the password, most freeware or open source PDF readers ignore the permission “protections” and allow the user to print or make copy of excerpts of the text as if the document were not limited by password protection.

The signature is used to validate that the permissions have been granted by a bona fide granting authority. For example, it can be used to allow a user [32]. For example, Adobe Systems grants permissions to enable additional features in Adobe Reader, using public-key cryptography.

Adobe Reader verifies that the signature uses a certificate from an Adobe-authorized certificate authority. Any PDF application can use this same mechanism for its own purposes.

For example, Adobe Systems grants permissions to enable additional features in Adobe Reader, using public-key cryptography. Adobe Reader verifies that the signature uses a certificate from an Adobe-authorized certificate authority.

Any PDF application can use this same mechanism for its own purposes. Under specific circumstances including non- patched systems of the receiver, the information the receiver of a digital signed document sees can be manipulated by the sender after the document has been signed by the signer. PDF files can have file attachments which processors may access and open or save to a local filesystem.

PDF files can contain two types of metadata. This is optional and is referenced from Info key in the trailer of the file. A small set of fields is defined and can be extended with additional text values if required. This method is deprecated in PDF 2. PDF documents can also contain display settings, including the page display layout and zoom level in a Viewer Preferences object.

Adobe Reader uses these settings to override the user’s default settings when opening the document. PDF files can be created specifically to be accessible for people with disabilities. Some software can automatically produce tagged PDFs , but this feature is not always enabled by default. Adding tags to older PDFs and those that are generated from scanned documents can present some challenges.

One of the significant challenges with PDF accessibility is that PDF documents have three distinct views, which, depending on the document’s creation, can be inconsistent with each other. The three views are i the physical view, ii the tags view, and iii the content view. The physical view is displayed and printed what most people consider a PDF document. The tags view is what screen readers and other assistive technologies use to deliver high-quality navigation and reading experience to users with disabilities.

The content view is based on the physical order of objects within the PDF’s content stream and may be displayed by software that does not fully support the tags’ view, such as the Reflow feature in Adobe’s Reader. Interactive Forms is a mechanism to add forms to the PDF file format. Both formats today coexist in the PDF specification: [32] [48] [49] [50]. AcroForms were introduced in the PDF 1.

AcroForms permit using objects e. Alongside the standard PDF action types, interactive forms AcroForms support submitting, resetting, and importing data. The “submit” action transmits the names and values of selected interactive form fields to a specified uniform resource locator URL. The entire document can be submitted rather than individual fields and values, as was defined in PDF 1. AcroForms can keep form field values in external stand-alone files containing key-value pairs.

Anyone may create applications that can read and write PDF files without having to pay royalties to Adobe Systems ; Adobe holds patents to PDF, but licenses them for royalty-free use in developing software complying with its PDF specification.

At the same conference, they additionally showed how to exfiltrate the plaintext of encrypted content in PDFs. PDF attachments carrying viruses were first discovered in It was activated with Adobe Acrobat, but not with Acrobat Reader. From time to time, new vulnerabilities are discovered in various versions of Adobe Reader, [63] prompting the company to issue security fixes. Other PDF readers are also susceptible. One aggravating factor is that a PDF reader can be configured to start automatically if a web page has an embedded PDF file, providing a vector for attack.

If a malicious web page contains an infected PDF file that takes advantage of a vulnerability in the PDF reader, the system may be compromised even if the browser is secure. Disabling JavaScript execution in the PDF reader can help mitigate such future exploits, although it does not protect against exploits in other parts of the PDF viewing software. Security experts say that JavaScript is not essential for a PDF reader and that the security benefit that comes from disabling JavaScript outweighs any compatibility issues caused.

Long gone are the days where you have to print a PDF, sign it, scan it, and email it back. There is also an option to add your personal information to an autofill collection, so you can save time when a form requires you to add your name, age, address, etc. Acrobat Pro DC also has tools that can help you organize documents that you send out for signatures.

The document tracker will show you which files are still waiting for a signature, and then it will automatically store the document once it is signed. The first is the Acrobat Reader, which has nearly the same level of functionality as the desktop version. You can make edits, comments, share, sign, track documents, and access your files. The second app is Adobe Scan.

Use your camera to capture any document, receipt, or picture, and Adobe will upload it to your cloud storage. The scan app has some editing options, such as rotating, cropping, and straightening the image. It uses Adobe Sensei to enhance lines, handwriting, and printed text and removes unnecessary shadows and glares. Acrobat Pro DC uses a modern tabbed interface that makes it easy to navigate and work on multiple files at once.

This is where you see the most recently viewed documents and files uploaded from the Adobe Scan app. You can also quickly load documents that are stored on your computer, Adobe Document Cloud, or connect it with other cloud storage services like Google Drive, OneDrive, SharePoint, and Dropbox. You can also open a tab to see which documents have been sent out and are still waiting for a signature.

Now, I take advantage of the digital signature tool and get all forms back in on time. What I found really cool is the OCR feature.

It finds the font used in the PDF, so the edits look natural. It was quick and easy, with just a few clicks of the mouse or taps on the tablet, and within seconds I had the files in the format I needed. While I found the features and tools to be fairly straightforward, I was happy to see that Adobe has an excellent help section.

It goes through each tool, with both video and text tutorials, to ensure that all users will get the most out of each feature. Follow this step-by-step guide to cancel your account. Adobe Acrobat Pro DC has a free trial for seven days.
