Questions

Is my PDF uploaded?

No. Files are processed entirely in your browser with local technology and are never sent to a server.

Is there a file size or usage limit?

There is no account and no quota; the practical limit is the memory of this device.

Is the processed file identical to the original?

Merge, split, rotate and password operations keep page content intact; compression is a lossy re-render and reduces quality according to the chosen level.

What is PDF Tools?

PDF Tools is a set of local PDF tools — merge, split, page management, passwords, image export, watermarks, compression and form filling — usable offline.
