Frequently asked questions

Do I need to know the current password?+

Yes. You must know the existing password to decrypt a file you own; this tool removes protection, it does not crack unknown passwords.

Is this only for PDFs I created myself?+

This tool is intended for PDFs you own or have the right to unlock, such as your own encrypted documents or files a colleague protected for you.

Will unlocking change the PDF content?+

No. Only the password protection is removed, all pages, text, and images stay exactly as they were.

Is my password sent to a server?+

No. Decryption runs in your browser, so your password and file never leave your device.

Is Unlock PDF free?+

Yes. Unlock PDF is free to use with a light hourly limit. Upgrade to Pro for unlimited use, larger files and batch processing.

Do I need to create an account?+

No. You can use the tool right away without signing up. An account is only needed if you want to save files to your NativeDoc cloud.

Are my files safe?+

Yes. Files are processed securely and are never shared. Most tools run right in your browser, so your document doesn't leave your device unless you choose to save it.

Will there be a watermark?+

No. NativeDoc never adds a watermark to your files, on the free tier or Pro.
