Why use Unlock PDF?
Password-protected PDFs stop casual opening, but legitimate workflows still need an unencrypted copy for editing or archival. PDFBaba unlocks files when you already know the document open password—there is no password cracking or recovery service. This respects both ethics and practicality. Uploads are deleted after about one hour, and you do not need an account. After unlocking, you can edit, split, or compress the decrypted file with other tools. If you only have permissions passwords, read the tool hints for owner-password edge cases.
Supported files & limits
One encrypted PDF plus the known open password. The default upload limit is 100MB per file; administrators can raise or lower this via server configuration. We do not crack passwords; you must already have access.
Privacy & data retention
PDFBaba is built for quick tasks: your uploads and generated downloads are kept only long enough to process your request and are automatically deleted after about one hour. We do not require signup for these tools, and we do not use your documents to train AI models. For full details on cookies, analytics, and legal terms, read our Privacy Policy.

Frequently Asked Questions
What password should I use?
Use the same password you use to open the PDF in a reader app (document open password). If you only know an owner or permissions password, leave the first field empty and enter it in the optional second field.
Can PDFBaba recover a forgotten password?
No. Unlocking only works when you already know a valid password. We cannot crack or guess passwords.
How long are files kept?
Uploaded and generated files are automatically deleted after one hour.
Do I need an account or signup?
No. PDFBaba does not require signup for these tools. Upload, process, and download without creating an account.
Is there a watermark on the output?
Output from this tool is not watermarked by PDFBaba. You get a clean file suitable for work and sharing.
What is the maximum file upload size?
The default limit is 100MB per file on the server. Your host or administrator can change this via environment configuration. If a file fails to upload, try compressing or splitting it first.
Can I use this tool on my phone or tablet?
Yes. PDFBaba works in modern mobile browsers. Very large files or complex previews may be smoother on a desktop with a stable connection.
Is there a daily usage limit?
To keep the service fast for everyone, rate limits may apply per IP. Typical personal use is rarely affected. If you hit a limit, wait briefly and try again.
