Fifty PDF tools you can also run on your own machine in Docker.
An open-source PDF workbench with more than fifty operations — split, merge, OCR, redact, sign, convert, repair, compare — laid out as a dashboard rather than as fifty separate landing pages. The hosted version is the convenient one; the point of the project is that you can run the identical thing in a Docker container so no document ever reaches a third party. Enterprise features sit behind a paid tier.
AltFTool does this too
If you would rather not leave the site, PDF Password Remover covers the same job here — free, no account, and it runs in your browser.
