If a PDF asks for a password every time you open it — or won't let you print, copy, or edit it even though you know the password — you don't have to keep typing it in forever. You can remove the password from the file itself, once, and have a normal PDF afterward. Here's how to unlock a PDF online with pdfCraft's unlock tool.
What does it mean to unlock a PDF?
This tool removes a password you already know from a PDF — it doesn't crack, guess, or bypass one you don't. If you've genuinely forgotten the password, pdfCraft can't recover it for you; that's true of any legitimate tool, since PDF passwords are enforced with real encryption, not just a UI lock.
What it does solve: you have the password (maybe it came from your bank, your employer, or a contract you signed), and you're tired of entering it every time, or you need to share the file with someone else without also sharing the password.
Can you remove a PDF password without knowing it?
No. There's no legitimate way to remove a PDF's encryption without the correct password — pdfCraft (or any real tool) can't guess, brute-force, or bypass it. If you've lost the password entirely, your options are to track it down from whoever sent you the file, or recreate the document from an unprotected source if you have one.
Step 1: Upload your password-protected PDF
Go to Unlock PDF and drop in your document. No account is needed. On the free plan you can unlock files up to 50 MB and 50 pages, with 25 exports a day per device.
Step 2: Enter the password
Type in the PDF's current password. This is the same password you'd normally enter to open the file — pdfCraft uses it to decrypt the document, not to guess or brute-force anything.
Step 3: Download your unlocked PDF
Once the password's verified, pdfCraft gives you back the same PDF with the encryption removed. Open it, print it, copy from it — no password prompt, no restrictions.
Which PDF encryption types can be removed?
PDF password protection comes in a few different flavors depending on what software created it, and not every tool supports every flavor. Here's exactly what pdfCraft's unlock tool can remove:
| Encryption | PDF version | Key length | Supported |
|---|---|---|---|
| RC4 40-bit (V=1, R=2) | PDF 1.1+ | 40-bit | ✅ Yes |
| RC4 128-bit (V=2, R=3) | PDF 1.4+ | 128-bit | ✅ Yes |
| AES-128 (V=4, R=4) | PDF 1.6+ | 128-bit | ✅ Yes |
| AES-256 (V=5, R=6) | PDF 2.0 | 256-bit | ✅ Yes |
That's every encryption method defined by the PDF spec's standard security handler — whatever produced your protected PDF (Adobe Acrobat, macOS Preview, or any other "protect this PDF" tool), pdfCraft can remove it.
If you're not sure which type your file uses, you don't need to figure it out yourself — just try uploading it.
What happens to your file
Your PDF is uploaded over an encrypted (HTTPS) connection so pdfCraft can decrypt it with the password you provide, and it's deleted after you download the unlocked copy. pdfCraft doesn't store or share your documents or passwords.
How to remove print and copy restrictions from a PDF
Some PDFs don't ask for a password to open at all, but still block printing, copying, or editing — that's an "owner password" restriction rather than an "open" password. The same unlock flow handles both: pdfCraft detects any password protecting the file (open or owner-level) and removes it along with the encryption, so you get back a fully unrestricted PDF either way.
When to remove a PDF password
- Removing a password from a bank statement or bill so you can forward it without sharing the password too
- Unlocking a contract or report you need to edit, annotate, or merge with other files
- Clearing print/copy restrictions on a document you have every right to use freely
- Prepping a file for an automated workflow that can't handle a password prompt
Once a file's unlocked, you might want to merge it with other documents, sign it, or add your own password protection with permissions you actually choose.
Frequently asked questions
Can pdfCraft crack or recover a forgotten PDF password?
No. This tool removes a password you already know — it isn't a password-cracking or brute-force tool. If you don't have the password, pdfCraft (like any legitimate tool) can't open the file for you.
What encryption types does the unlock tool support?
RC4 (40-bit and 128-bit), AES-128 (V=4, R=4), and AES-256 (V=5, R=6) — every encryption method defined by the PDF spec's standard security handler, including everything Adobe Acrobat and macOS Preview produce by default.
Is it free to unlock a PDF?
Yes. Unlocking is free with no account needed, within the free limits: 50 MB per file, up to 50 pages, and 25 exports per day per device.
How do I remove a password from a PDF for free?
Go to pdfCraft's unlock tool, upload your PDF, and enter the password. Then download the unlocked copy — no account or payment needed, as long as your file is within the free plan's limits (50 MB, 50 pages, 25 exports a day per device).
Does pdfCraft store my file or password?
No. Your file is sent over an encrypted connection to be decrypted with the password you provide, and it's deleted after you download the result. Passwords aren't stored either.
Will unlocking remove print or edit restrictions too?
Yes. Removing the encryption removes both the open password and any owner-level restrictions (printing, copying, editing) set on the file — you get back a normal, unrestricted PDF.
Is it safe to unlock a PDF online?
Yes — your document is sent over an encrypted (HTTPS) connection, decrypted to produce the unlocked copy, and then deleted (see "What happens to your file" above). Nothing is stored or shared.
Can I unlock a PDF on my phone?
Yes. pdfCraft runs in your mobile browser the same way it does on desktop — no app to install. Upload the file, enter the password, and download the unlocked copy.
