What this tool is for
Unlock PDF saves an unencrypted copy of a document you are authorized to access, using its known open or owner password. Processing happens in a local browser worker. Text and graphics stay in PDF form; pages are not converted into images. Your original is unchanged.
How to remove a password from PDF
- Choose or drop one PDF. We check its encryption locally.
- Enter the password you know and choose Unlock PDF. If it is incorrect, you can try again.
- Review the result and choose Download unlocked PDF. Keep your original and check the new copy before sharing.
A few things to know
Can I unlock a PDF without knowing its password?
No. This tool does not guess, crack or recover passwords. It attempts only the password you submit. For a document with an empty open password, explicitly submit an empty field.
Are my PDF or password uploaded?
No. Both stay in browser memory during local processing. The password field clears when you submit, replace the file or reset. Download links are released when you reset or leave the page.
Which encryption methods work?
Tested Standard Security Handler variants are RC4-40 revision 2, RC4-128 revision 3, AES-128 revision 4 and AES-256 revision 6, with open and owner passwords. Revision 5, certificate encryption, custom security handlers and unusual crypt filters are not supported.
Will the content and signatures stay the same?
Page order, size, rotation, selectable text, vectors and image streams are retained. Standard forms, annotations, links, outlines and metadata are kept where supported. Rewriting invalidates digital signatures. Dynamic XFA forms and specialized interactive features are not supported or guaranteed; always check important documents.
What if my PDF has no password?
We tell you it is not password protected. No unnecessary replacement file is generated.
Why might a large PDF fail?
Decryption and saving need more memory than the file itself. We check an estimated memory budget, page and object counts, and stop jobs that take too long. Complex files may need a desktop PDF application, especially on low-memory devices.
