How to Unlock a PDF Online Free — 3 Steps
Upload your protected PDF
Drag and drop your password-protected PDF into the unlocker. The tool accepts all types of encrypted PDFs — owner passwords, user passwords, and permission-restricted documents.
Enter the password (if known)
Type the PDF's password to authorize removal. If you don't have the password but have permission to access the file, the tool attempts permission-based unlocking. All processing stays in your browser.
Download the unlocked PDF
Click Unlock and download your PDF immediately — now fully editable, printable, and copyable. The original file quality is preserved, and no watermarks are added.
Why Use PDFBro to Unlock PDFs
Frequently Asked Questions
Can I unlock a PDF without knowing the password?
PDFBro can remove owner-level protection (printing, copying, editing restrictions) even without the password. However, removing a user/open password requires you to enter it. PDFBro never attempts to crack or brute-force passwords.
Is it safe to unlock PDFs online?
Yes. PDFBro processes files entirely in your browser — your PDF never leaves your device. No file is uploaded, stored, or accessible by anyone else. This is safer than server-based unlockers that upload your sensitive documents.
What types of PDF protection can be removed?
PDFBro removes both owner passwords (restrictions on printing, copying, editing) and user/open passwords (the password to open the file). It works with PDF 1.0 through 2.0 and AES-128/256 encryption.
Will unlocking affect my PDF's formatting or content?
No. Unlocking only removes the encryption layer and permission restrictions. Your PDF's text, images, fonts, and layout remain completely unchanged. The file is structurally identical — just no longer locked.
Are there any file size or daily usage limits?
No. PDFBro accepts PDFs up to 100 MB and has zero daily limits. Unlock as many PDFs as you need — no account required, no throttling, no premium tier.
Does the unlock tool work on mobile?
Yes. The unlock PDF tool is fully functional on mobile browsers including Safari on iPhone and Chrome on Android. Upload, unlock, and download directly to your phone.
