Remove Password Protection from PDF
Once you enter the correct password, our tool strips all protection parameters from your PDF file. This includes removing the document open password as well as all restriction permissions.
The resulting output PDF will have no security locks, meaning you can open it on any device without entering a password, print it, copy text, or edit it freely.
When Should You Unlock a PDF?
Securing files is excellent for transmission, but having to type a password every time you open a receipt, statement, or contract can be tedious. Unlocking a PDF is ideal when:
- You need to archive files in a folder where you require quick previews without password prompts.
- You want to combine multiple separate files into one single PDF using our Merge tool.
- You need to send the document to a platform or portal that does not support encrypted uploads.
Only Unlock PDFs You Own or Have Permission to Access
MarsPDF respects intellectual property and privacy laws. You must only upload and unlock PDF files that you own, that you created, or for which you have explicit authorization and legal permission from the owner to decrypt.
Using online tools to bypass security parameters on files you do not own or are not authorized to access is illegal and violates our Terms of Use.

Your privacy and document security are fully guaranteed. All files uploaded to MarsPDF are transferred and processed securely over encrypted HTTPS connections.
