v3.0.0

2026-09-24

Stirling PDF V3.0 is live! With this update we are introducing a lot of exciting new changes, A brand new automation system, Free OAuth SSO for all, brand new text editor and a ton of new features, bug fixes and security fixes

We have a new system along side the “PDF Editor” called the “PDF Processor” The PDF Processor takes the tools you already use in Stirling PDF and lets you run them across a large numbers of files with a variety of sources (Folders/FTP/S3 etc) The idea is, If you need to OCR 10,000 files, Compress a whole folder or convert a whole document library this should be a tool which can help with that and allow it to listen and run for future files as they arrive This is the first major release of Processor and we will be improving it quickly based on how people use it. Full Processor guide with examples AI is also available as an optional part of Processor. You can use AI to understand documents, classify them, extract information, and help automate processing. AI is fully optional (and off by default) and can use various models including locally/self-hosted models depending on your setup. Automation now includes 1,000 PDFs per month free. This allowance applies to automated processing through Processor, API, and AI features. Linking your server to stirling.com gives you an additional 500 PDFs per month and access to our hosted AI (If you dont want to host your own). Normal PDF Editor usage remains free and unlimited. In addition, we are also making OAuth SSO free for all users.

V3.0 also includes major improvements to the PDF Editor side of things:

  • The already mentioned free OAuth SSO
  • Brand new Text Editor, now out of alpha you should expect drastic better UI, performance and compatibility
  • Improved Form Editor and form creation
  • Auto form detection
  • New Quick access bar
  • Auto rotate
  • Major redaction improvements
  • PDF/UA conversion (WIP)
  • PDF Portfolio support

  • Sign from your phone using a QR code
  • RFC3161 timestamps
  • Search across all Stirling PDF
  • Mobile UI improvements
  • File handling and file history improved for desktop so deleted files delete in stirling UI
  • Brand new Files Library
  • New desktop folders to mount folders from disk into stirling to run automation on (Will be expanded on in future updates)
  • Brand new Settings Page
  • Smarter tool suggestions based on previous tool usage
  • General UI improvements and bug fixes
  • Several bug fixes and security improvements!

Please try V3.0 and let us know what you think. We will be shipping fixes, improvements, and new Processor and editor capabilities over the next few weeks with releases expected to be near weekly, with a greater focus on community PRs going forward.
