The PDF is one of the most popular formats to distribute documents. It allows users to view embedded documents within applications online, without the use of a third party tool. Applications looking to support PDF documents should not rely on third party tools (Adobe Acrobat, MS Tools etc.) to view these documents. Currently there are minimal tools that support standard PDF specifications-based documents in their viewers.
The Viewer supports popular PDF Features you can use while viewing PDF documents. Have a look on the features below:
GcDocs PDF Viewer supports both Page-level and Document-level attachments. You can view the attachments in the left pane's Attachment panel and open the attachments from within the viewer by double-clicking on the attachment files.
Visit Our Demo (Open the Attachments panel from top left menu of the viewer.)
The viewer supports filling forms, submitting it, and resetting the filled form within the viewer. With some coding, you can also save the filled form using GrapeCity Documents for PDF API on the server.
Once you fill the form, you can directly print from the "print option" in the viewer or save as a PDF.
The viewer provides the option to rotate the document pages clockwise. The rotated document can be printed directly from the viewer through the Print option.
Page labels in PDF documents allow users to subdivide the document into sequences of logically related page ranges (e.g., preface, main body, postface). The viewer supports displaying page labels titles, allowing you to distinguish the content topic while scrolling through the document.
Visit Our Demo (Open the Thumbnails panel from top left menu of the viewer. Observe the Page Labels.)
An article thread is a sequence of related pages or page areas that can be navigated sequentially (forward or backward) in a PDF viewer. The GcDocs PDF Viewer supports navigating through article threads in a PDF document through a separate panel for Article Threads in the sidebar. The example below shows navigating through article threads of a PDF document that arranges pictures associated (via known file names) with a specific subject (buildings, art, etc.) put into subject-specific article threads. The article thread navigation UI is similar to that in Adobe Acrobat.

Users can now listen to sound messages in PDF documents using GcDocs Pdf Viewer.
In addition, the viewer supports most annotations in the PDF document, such as:
These display with full support, without loss of any properties

PDF documents also include Outlines (bookmarks) to jump to specific locations in the document. The GcDocs PDF Viewer supports the Outline panel that can list the outlines and navigate to different positions in the document.

To directly select text in a PDF document and copy paste to some other document, you can use the Text selection caret, available by default in the GcDocs PDF Viewer. The Viewer also supports selecting vertical and RTL text.
Password-protected documents are fully supported in the GcDocs PDF Viewer. If your documents are password protected, open the document through the password input dialog supported in the viewer.
GcDocs PDF Viewer supports all standard viewer features:
See Help for more description on these features.
You can easily embed the PDF Viewer in any of the major web frameworks:
GcDocs PDF Viewer together with the GcPdf API, can load several real-time PDFs based on Adobe PDF specification 1.7.
With the power of a server-side API and a client-side viewer, you can achieve the full-fledged PDF needs of your application. From displaying annotations, password protected documents, page labels, and article threads, PDF attachments offers full form handling like filling and submitting PDF forms on server. You can implement a full application workflow to collect user inputs and store them as PDF documents.
The GcDocs PDF Viewer is available with a GcPdf license, so you get two powerful components: server-side and client-side to develop full PDF applications.
The image above shows a PDF document with Japanese text created with GcPdf and then loaded into the GcDocs PDF Viewer, as well as the Image Links that use LinkAnnotation to jump from one location to another from within the viewer.
