1
Upload your protected PDF — or several at once — from your device, or pull them from Google Drive, Dropbox, or OneDrive. Only password-protected PDFs are accepted: the tool detects encryption and skips any file that isn't locked. Without an account: 1 file, up to 80 MB. With a free account: up to 3 files at once, 80 MB each (120 MB total).
2
Enter the password that opens each file. Unlocking several files that share one password? Turn on the master password to type it just once for the whole batch. If you only forgot an owner password (used for print or copy restrictions, not for opening), use the forgot-password option and confirm you own the file.
3
Click Unlock PDF. We verify the password and strip the encryption from each document.
4
The output is a normal PDF — or a ZIP when you unlock several — that opens straight away, with no password prompt and no editing restrictions.
5
Download your unlocked file, save it back to the cloud, or send it straight into another tool like Edit PDF or Merge — the unlocked PDF is carried across, so there's no re-upload.
Password removed cleanly
The encryption layer is stripped from the file, leaving a normal PDF you can open and edit anywhere.
Needs your current password
Enter the password you already use to open the file. We do not crack or guess - just remove what you authorise.
Unlock several at once
With a free account, unlock up to 3 protected PDFs in one batch. Files that share a password can be unlocked with a single master password, and the results come back as a ZIP.
Only protected PDFs
The tool detects encryption and accepts only password-protected files, so there is no confusion about what actually needs unlocking.
Restrictions lifted
Print, copy, and edit limits that were tied to the password are removed at the same time, so you get a fully usable PDF back.
Original quality preserved
Pages, text, images, and metadata are kept exactly as in the source. Only the lock is gone.
Opens anywhere
The unlocked file opens normally in Adobe Acrobat, browsers, mobile readers, and any standards-compliant PDF tool.
Cloud import & save
Pull files from Google Drive, Dropbox, or OneDrive, and save the unlocked PDF straight back - no local download step.
Workflow Ready
Send the unlocked PDF straight into Edit PDF, Merge, or any other tool - the file is carried across, so there is no need to re-upload.
Private and secure
Files are processed over HTTPS and deleted from our servers shortly after the job finishes. Your password is never stored.
Free, no watermark
No watermark on the PDF and no signup needed for a single file; a free account raises the batch to 3 files.
PDF 怎么去掉密码？
在上方添加 PDF，输入它的密码并解密，即可下载一份打开时不再需要密码的副本。完全免费，无水印，无需注册。
不知道密码能解密 PDF 吗？
要看是哪种锁。如果 PDF 能正常打开，只是禁止打印、复制或编辑，可以：不需要密码就能去除这些限制。如果打开 PDF 需要密码而你忘记了，就不行：我们绝不破解或猜测密码，请向发件人索要密码或未加密的副本。
PDF 怎么去除权限限制，解除禁止复制、打印？
添加 PDF。如果它不需要密码就能打开、只是设置了权限限制，系统会自动识别，无需输入任何内容。解密后下载的副本可以打印、复制文字和编辑；要修改文字，可再用 Editly 打开。
去除了权限限制，为什么手机上打开还要密码？
这说明文件还设置了打开密码。请在这里输入该密码进行解密，下载的新文件（文件名以 -unlocked.pdf 结尾）就能直接打开。注意要打开的是新下载的文件，原文件始终保留密码。
PDF 加密后忘记密码怎么解除？
忘记的打开密码无法在这里破解。请向文件发送方索要密码或未加密的副本。如果文件只限制了打印或复制，则无需密码即可解除。
手机上怎么给 PDF 解密？
在手机浏览器（Safari、Chrome 等）中打开本页，添加 PDF，有密码就输入密码，然后解密，无需安装 App。解密后的 PDF 保存到下载目录。
可以批量解密 PDF 吗？
免费账户一次最多 3 个 PDF（单个 80 MB，总计 120 MB），可以共用一个密码，也可以每个文件单独输入。解密后的文件打包成一个 ZIP 下载。
解密会改变 PDF 的内容吗？
不会。只去掉加密，页面、文字、字体、图片、链接、书签和表单域都保持原样。
怎么给 PDF 设置密码？
使用 加密 PDF。它用你设定的密码加密文件，还可以禁止打印、复制和编辑。
密码安全吗？
安全。密码通过 HTTPS 加密传输，只用于解密这个文件，用完即删除。文件在一小时内自动删除。在 浏览器模式 下，解密在你自己的设备上完成，文件和密码都不会上传。
