  • Available on any desktop, server, mobile, or web platform supported by PDFTron SDK.
  • Simple to use and deploy.

linkPDF/A Add-on

PDF/A component allows developers to convert generic PDF documents to PDF/A (ISO 19005-1).

  • Checks if a PDF file is compliant with PDF/A (ISO 19005-1) specification.
  • Converts any PDF to a PDF/A compliant document.
  • Supports PDF/A-1a PDF/A-1b, PDF/A-2a PDF/A-2b, PDF/A-2u, PDF/A-3a PDF/A-3b, PDF/A-3u.

  • Allows user to customize compliance checks or omit specific changes during the conversion process.
  • Supports user-defined color profiles.
  • Offers automatic font substitution, embedding, and subsetting options.

linkPDF Redaction Add-on

PDF Redaction component offers options to remove (not just covering or obscuring) content within a region of PDF. With printed pages, redaction involves blacking-out or cutting-out areas of the printed page. With electronic documents that use formats such as PDF, redaction typically involves removing sensitive content within documents for safe distribution to courts, patent and government institutions, the media, customers, vendors or any other audience with restricted access to the content. The redaction process in PDFTron SDK consists of two steps:

  • Content identification: A user applies redact annotations that specify the pieces or regions of content that should be removed. The content for redaction can be identified either interactively (e.g. using ‘pdftron.PDF.PDFViewCtrl’ as shown in PDFView sample) or programmatically (e.g. using ‘pdftron.PDF.TextSearch’ or ‘pdftron.PDF.TextExtractor’). Up until the next step is performed, the user can see, move and redefine these annotations.
  • Content removal: Using ‘pdftron.PDF.Redactor.Redact()’ the user instructs PDFTron SDK to apply the redact regions, after which the content in the area specified by the redact annotations is removed. The redaction function includes number of options to control the style of the redaction overlay (including color, text, font, border, transparency, etc.).

PDFTron Redactor makes sure that if a portion of an image, text, or vector graphics is contained in a redaction region, that portion of the image or path data is destroyed and is not hidden with clipping or image masks. PDFTron SDK API can also be used to review and remove metadata and other content that can exist in a PDF document, including XML Forms Architecture (XFA) content and Extensible Metadata Platform (XMP) content.

linkPDF Optimizer Add-on

PDF Optimizer component optimizes PDF documents by reducing the file size, removing redundant information, and compressing data streams using the latest in image compression technology. PDF Optimizer can compress and shrink PDF file size with the following operations:

  • Remove duplicated fonts, images, ICC profiles, and any other data stream.
  • Optionally convert high-quality or print-ready PDF files to small, efficient and web-ready PDF.
  • Optionally down-sample large images to a given resolution.
  • Optionally compress or recompress PDF images using JBIG2 and JPEG2000 compression formats.
  • Compress uncompressed streams and remove unused PDF objects.

linkPDF Flattener (Mobile PDF Optimizer) Add-on

PDF Flattener component (pdftron.PDF.Flattener) can be used to speed-up PDF rendering on mobile devices and on the Web.

PDF documents can frequently contain very complex page description (e.g. thousands of paths, different shadings, color spaces, blend modes, large images etc.) that may not be suitable for interactive viewing on mobile devices.

Flattener can be used to speed-up PDF rendering on mobile devices and on the Web by simplifying page content (e.g. flattening complex graphics into images) while maintaining vector text whenever possible.

A quick way to try Flattener is by using DocPub CLI (e.g. docpub -f pdf my.pdf). If you prefer working with code, please take a look at the last code snippet in the Optimizer sample (which is included part of PDFNet).
