Does PDFWix send my password to a server?

No. The decryption runs entirely in your browser using JavaScript and WebAssembly — your password and PDF stay on your iPhone. Verify in Safari DevTools (no upload requests during the unlock).

What's the difference between an open password and an owner password?

An open (user) password is required to view the document. An owner password restricts what you can do with the document (print, copy, edit) without restricting opening it. Unlock PDF removes either type when you supply the matching password.

How to Unlock a PDF on iPhone

A simple step-by-step guide to unlock a pdf on iPhone using PDFWix's free online tools.

How to Unlock a PDF on iPhone

Unlock a PDF on iPhone in Safari with PDFWix — remove a known password, files stay on your device. Free, no app install, no signup, no watermark, iOS 16+.

Tip: unlock then compress for sharing

If a colleague sends you a password-protected PDF and you need to forward it to someone else without the password header (e.g. uploading to a school portal that doesn't accept encrypted PDFs), unlock first in Safari with PDFWix Unlock, then optionally compress before uploading. Both tools run in Safari with no app install and no upload to our servers. Re-encrypt with Protect PDF if you still want the forwarded copy password-locked, this time with a password the recipient can use.

How it works

Open PDFWix Unlock PDF — Open Safari on your iPhone and go to pdfwix.com/unlock-pdf.
Add the protected PDF — Tap Select file and choose the password-protected PDF from Files or iCloud Drive.
Enter the current password — Type the password you'd normally use to open the document.
Decrypt — Tap Unlock PDF — decryption runs locally in your browser on your iPhone.
Save the unprotected PDF — Tap Download, then 'Save to Files' — the unencrypted PDF lands in your Files app.

Frequently asked questions

Can PDFWix unlock a PDF if I don't know the password?

No — and this is the most important thing to understand about every legitimate 'unlock PDF' tool. PDFWix decrypts using the password you supply; it does not crack, brute-force, or recover unknown passwords. If you've lost a password you set yourself, the file may be unrecoverable — that's by design with strong PDF…

Is unlocking a PDF I own legal?

Yes. Removing a password from a PDF you own (or have explicit permission to modify) is legal in most jurisdictions. Removing protection from a file you don't own is generally illegal under computer-misuse laws and violates our terms of service.

Can I unlock a PDF on iPhone without an app?

Yes — in Safari at pdfwix.com/unlock-pdf. No app install, no signup, no Apple ID required. The decryption runs entirely in your browser on iOS 16 and later.
