Unlock PDF
Unlock PDF is a free browser tool that lets you remove password from a pdf you own. Pages are read and rewritten inside your browser with the PDF-lib engine, so the document never travels to a server and nothing is stored after you close the tab. It is used most by small firms handling client paperwork without a paid Acrobat licence. Handles standard PDF 1.4–1.7 files, including ones produced by Word, Google Docs, Canva and scanner apps. It stays free with unlimited use, and there is no watermark on anything it produces.

- Built to do one job properly rather than twenty jobs badly.
How to use Unlock PDF
- Add your PDF: Drag the file onto the drop area, or click it to browse your device. Several files can be added at once where the tool supports it.
- Set the options: Choose page ranges, order or output settings. The preview updates so you can confirm before committing.
- Download the result: Press the action button and the finished PDF saves straight to your downloads folder.
Frequently asked questions
- Will Unlock PDF reduce the quality of my pages? — No. Unlock PDF copies pages at their original resolution and keeps embedded fonts and images untouched, unless you deliberately choose a compression option.
- What is the largest file Unlock PDF can handle? — There is no hard limit set by us — the practical ceiling is your device's memory. Documents up to about 100 MB are routine; several-hundred-megabyte scans may be slow on an older phone.
- Can Unlock PDF open a password-protected PDF? — Not while it is encrypted. Remove the password in the app that created the file first, then the tool can read it normally.
- Does Unlock PDF add a watermark? — Never. Unlock PDF produces a clean file with no branding, stamp or trial marking of any kind.
