A powerful, locally-hosted web toolkit for working with PDFs: merge, split, compress, convert, rotate, watermark, OCR, sign and more — all in your browser, with files never leaving your device.
Notes
Single container using the official multi-arch image. Mostly stateless; custom settings persist under the mounted configs directory.
Open-source contribution
A fixed amount per install goes to Stirling PDF, forwarded via GitHub Sponsors.
