About Stirling-PDF

Stirling PDF plans to drop LibreOffice for its own converter within two weeks

Stirling PDF 3.0 in late September added the PDF Processor for bulk jobs, optional AI and free OAuth SSO. Releases since have come about every two weeks: group signing by default in 3.1.0, a Page Editor in 3.2.0, viewer and annotation work in 3.2.x. 3.3.0 lets users pick the beta Stirling Office Convert in many more tools and adds Windows ARM64, lighter mobile scanning and caching.
