ImageGear PDF

ImageGear PDF enables developers to add comprehensive PDF functionality into their applications.


Integrate an advanced PDF SDK into your application.

With ImageGear PDF, you can add annotation, conversion, compression, and PDF manipulation capabilities to your application. Integrate the ability to merge, insert or remove pages, reorder pages, and more.

ImageGear PDF supports hundreds of file types. No matter where the document originates, our PDF SDK allows developers to add conversion functionality from a myriad of different file types to PDF or vice versa, depending on the end-user’s need.


Improve the overall size of saved PDF documents by reducing or removing data structures in a PDF document. Compress original PDF files by up to 45 percent, saving valuable space in your storage. ImageGear PDF analyzes the elements to apply optimal compression operations.

PDF Manipulation

Give your application the ability to process PDF documents to meet users’ needs: 

  • Merge multiple PDFs.
  • Split a PDF into multiple PDFs.
  • Rearrange pages within a PDF. 
  • Add pages or remove pages on a PDF.


ImageGear PDF enables users to add annotations to PDF documents. These added annotations are useful for defining vector objects across multiple pages of a document or other non-interactive applications. ImageGear PDF also provides a WinForms tool that can be used to add annotation and redlining to other parts of your application.

PDF Security

Secure your PDF documents with encryption and password access.  ImageGear PDF allows developers to:

  • Set or change the PDF document’s access permissions.
  • Set or change the encryption used and decide what gets encrypted.
  • Set or change the content that gets encrypted or not.
  • Set, change, or remove the secure PDF document’s password.

PDF Signature

Developers can add binding digital signatures to PDF documents, allowing users to detect unauthorized changes to a document. The types of digital signature allowed in ImageGear PDF are:

  • Approval Signatures: These mark the integrity of the document at the time of signing and authenticate the signer. This signature marks the current state of the document for future verification.
  • Certification Signatures: These are added to a document to protect the integrity of a document after its first creation, as well as the authenticity of the signer. ImageGear PDF can validate these signatures.

PDF Compare

ImageGear PDF gives end-users of your application the capability to compare text and image contents of two documents, saving a new document with the changes highlighted as markup.

PDF Forms

Give your application the ability to read and extract data, add form fields to an existing form, and fill out form fields with known values. Forms can be flattened and exported by users into a static text document.
