About Unlock PDF
Some PDFs ship with owner-password restrictions that block printing, copying text, or editing — even when you have full read access. SnapToolz' Unlock PDF removes those owner-level restrictions locally in your browser. The result is a fresh PDF with the exact same content but no permissions flags, so you can print it, copy text out of it, and annotate it in any reader. Important scope note: this works on owner-password protections only (the kind set by PDF generators to discourage editing). PDFs that need a user password to open are NOT cracked — opening those requires the password. Everything runs client-side; your file never leaves your device.

How it works
- 1
Drop the locked PDF
Drag the PDF that you can open but can't print, copy from, or edit.
- 2
Run unlock
SnapToolz reads the file with pdf-lib, strips the permissions dictionary, and rebuilds the document.
- 3
Download the open PDF
The new file has no restrictions — printing, copying, editing all work as expected.

Are my files uploaded to a server?
No. Every tool on SnapToolz runs entirely inside your browser using JavaScript and WebAssembly. Your file is read locally, processed in memory, and the result is offered as a download. Nothing is sent to a server — there isn't one to send to.
Can SnapToolz unlock a password-protected PDF?
Only owner-password restrictions (the kind that limit printing, copying or editing once the PDF is open). PDFs that require a user password to open even read-only are not crackable — you need the password. This is a hard cryptographic limit, not a SnapToolz limitation.
Is it legal to unlock a PDF?
Generally yes if you own the PDF or have permission to use its content (e.g. you scanned a document yourself and forgot the restrictions you applied). Removing protections from documents you don't have rights to is a legal grey area in many jurisdictions — use your judgement.
Will the unlocked PDF look any different?
No — only the permissions metadata is removed. Pages, text, images, annotations, bookmarks, signatures and form fields are all preserved.
Does it work offline?
Yes. SnapToolz is a Progressive Web App. After your first visit, the app is cached on your device and every tool keeps working without an internet connection.
Is SnapToolz free?
Yes — every tool is 100% free with no sign-up, no watermark, no hidden tier. The whole platform is open source and we have no plan to gate features.
