Telerik Document Processing

PDF Processing


  • Overview

    The API contains two different editors, enabling you to choose between editing in a flow-like manner, or using the much more powerful and flexible fixed document structure and drawing on the page.
  • The document model of the library provides support for:


    Adding, modifying or removing of pages in a document. The properties enable you to change the size of the page, its rotation and more.

    Automatic layout

    Although the PDF format is fixed, sometimes you will need to insert the content in a way that flows on the page. RadPdfProcessing enables to achieve this easily by using blocks, tables and lists.


    Decoded on demand to achieve better performance. The API enables you to obtain the encoded image data. You can also control the image quality when saving the document.


    Enable you to describe the geometry of a 2D shape.

    Form XObjects

    The Form XObjects enables you to describe composite objects (consisting of text, images, vector elements, etc.) within a PDF file and reuse this content among the document, for smaller document size and better rendering performance.
  • Interactive Forms

    Create PDF files containing textboxes, radio-buttons, listboxes and other interactive controls making available for the PDF file user to interactively fill some data in the PDF document and/or digitally sign the filled document.
  • Digital signature

    The digital signature feature enables you to sign and validate PDF document.


    You can define the outline of other content elements like images and paths.


    Associate an object with a location on a page of the PDF document.


    Defines a particular view of a document.

    Colors and Color Spaces

    Support for different types of both.


    Support for the standard PDF fonts, Type0, Type1, CIDFontType2, TrueType and more.

    Text and Graphic properties:

    Provide options for changing the properties of the different elements in the document elements so you can achieve a unique look.


    Provides ability to protect your PDF content with or without using a password.

    Merge documents

    You may combine the pages of multiple PDF documents into a single PDF file.


    The API exposes a functionality that provides option for exporting PDF files with unmatched performance and minimized memory footprint. Extremely useful when you need to add some content to existing document, merge or split documents.

    Export to PDF and plain text

    Converting to plain text is very useful for indexing purposes, e.g. if you want “search” function in a bunch of PDFs.
