About

Every PDF tool in one place. Merge, split, compress, rotate, sign, convert, OCR, remove pages, all in the browser and all on your device.

Notes

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.

Single container using the official multi-arch image. Mostly stateless; custom settings persist under the mounted configs directory.

Alternative to: Adobe Acrobat, iLovePDF, Smallpdf
