Download or keep working
Download the protected PDF and store the password separately. Use Unlock PDF later if you need an editable copy.

Encrypt a PDF with an open password, owner password, or permission controls for printing, copying, and editing.
Free for daily work
No signup, no watermark, no daily caps. The free tier isn't a trial — it's the actual product.
Browser-first
Most operations stay on your device. We tell you exactly which ones don't, with a small label on every tool.
Cloud when it helps
Heavy AI, OCR, signing, and very large jobs use a one-time encrypted server session that's deleted as soon as the result is ready.
Chains, not exports
The output of one operation is offered as input to the next. No re-uploading the same file four times in a row.
