Unlock PDF
Unlock PDF removes passwords and permission restrictions (print/copy blocking) from PDF files you own or are authorized to access — 100% free with no usage limits. The entire decryption runs right in your browser: your file is never uploaded to any server.
When do you need it?
- Reopen old PDFs you password-protected yourself and now want to strip.
- Remove print restrictions on documents you are allowed to print.
- Re-enable content copying for quoting or re-entering data.
- Process files shared by colleagues or partners when you know the password.
- Batch-unlock internal archives so they are easier to manage.
Key features
- Removes open-password encryption when you enter the current password.
- Restores print, copy and edit permissions that were restricted.
- Runs 100% in your browser via WebAssembly — no uploads.
- Keeps all content, images and formatting exactly intact.

How to use
- Upload or drag & drop your file — everything runs right in your browser.
- Pick your options and hit the process button.
- Download the result — fast, free, no account required.
Safety & privacy
Your file is decrypted directly on your device using JavaScript and WebAssembly — never uploaded, stored or logged. Even the password you type stays in browser memory and is discarded when the tab closes. That is the biggest difference versus tools that force you to upload files to their cloud.
Genuinely free — no limits
KitsyApp is 100% free — no signup, no daily limits, no watermarks. Processing quality is on par with paid tools like Smallpdf or iLovePDF, and your files are processed on your own device instead of someone else's server.
Frequently asked questions
Can it open a PDF when I don't know the password?
No. The tool only unlocks files you are authorized to access — meaning you know the open password, or the file only has permission restrictions (print/copy) without an open password. That is both a technical and a proper legal boundary.
Are my files uploaded to a server?
No. Decryption happens in your own browser. You can even turn off Wi-Fi after loading the page and the tool still works.
Does the content change or lose quality?
No. Unlocking only removes the protection layer — all text, images, fonts and layout stay 100% identical to the original file.
Are there file size or usage limits?
No usage limits and no signup. File size only depends on your device's memory, since everything is processed locally.
