立即试用常见问题
Upload the password-protected PDF, enter the password you normally type to open it, and click Unlock PDF. The tool decrypts the file and gives you a copy that opens instantly with no password prompt. The original stays untouched on your device, so you can keep a protected version too.
usageNo, and that is deliberate. This tool removes encryption using the correct password you supply — it never cracks, guesses, or bypasses passwords. If the password you enter is wrong, decryption fails and you will see a wrong-password error. For a PDF whose password is truly lost, contact whoever created the document.
limitationsYes, completely free — no signup, no watermark, and no file limit beyond the standard upload size. Upload the PDF, enter its password, and download the decrypted copy without paying anything.
pricingYour PDF and password travel over an encrypted HTTPS connection, the file is decrypted on our secure servers, and both the upload and the unlocked result are automatically deleted. The password is used only to decrypt your file during processing and is never stored.
privacyThe tool removes the open (user) password — the one a reader must type before the document displays — including PDFs protected with AES encryption. As long as you can open the file with the password you have, the unlocked copy will open freely and print, copy, and edit normally in any PDF reader.
formatsYes. Our PDF Password tool does both directions: it can encrypt a PDF with a new AES-128 password or remove one you know. Use it whenever you want to re-protect the unlocked file before sharing it.
usage解锁 PDF 如何助您完成任务
它每天都在解决真实的问题——服务企业、创作者和日常任务。找到适合您的用例，几秒即可开始。
Stop typing the password on files you use daily
Bank statements, payslips, and insurance documents often arrive locked with a known password. Unlock your own copies once so they open instantly in any reader without the password prompt every time.
Prepare documents for printing and merging
Many printers, merge tools, and document systems refuse encrypted PDFs. Remove the password first so the file can be printed, merged, compressed, or archived like any normal PDF.
Archive unlocked copies of records you own
Password-protected archives become a problem years later when the password is half-forgotten. Store decrypted copies of your own records in your secure backup so they stay readable forever.
Share a document with people who should not need the password
When a supplier sends you a protected file that your whole team needs, unlock it once (with permission) instead of distributing the password to everyone.
