PDFgear
Edit, convert and ask questions about PDFs
Edit PDFs and automate document workflows on your own infrastructure

Stirling brings PDF reading, editing, and repeatable document processing into one workspace. Users can merge files, rearrange pages, compress documents, convert formats, and make scanned text searchable with OCR. Annotation, form filling, signing, and redaction tools support reviewing documents and preparing them for sharing. It is available in a browser, as a desktop application, or on a self-hosted server.
For recurring work, teams can build pipelines that apply a sequence of operations to batches of PDFs or newly arriving files. APIs and MCP connections let other systems call PDF operations, while processing views help teams investigate failed runs. Organizations can choose their deployment and configure the tools available to users; individual features depend on the selected setup.
