Protect PDF locks a document with an open password and optional limits on printing or copying. Share the password through a different channel than the file. Standard protection runs in your browser so the document stays on your device for that step.
Control PDF access with clear, reliable encryption tools with clear text and sharp details. We balance file size against readability so your result stays usable for email, portals, and print.
Files transfer over encrypted connections. We never sell your documents. Working copies are wiped from our secure infrastructure within two hours.
Works in Chrome, Safari, Firefox, and Edge on Mac, Windows, iOS, and Android — no app install for the standard flow.
Drag and drop your file, or choose it from your device.
Pick your settings, or keep the recommended defaults.
Save the finished file to your device in seconds.
Zero long-term retention. Encrypted transfer and automatic deletion after processing.
Optimized for quick browser runs so you spend less time waiting on uploads.
No desktop software. Open the page, upload, and download from any modern browser.
When a job needs more power, secure remote processing kicks in without changing your steps.
Predictable outputs for the formats we support — ready for email, portals, and sharing.
Your files are not used for ads. See our Privacy Policy for retention and security details.
Passwords cannot be recovered — store them securely. Only use Unlock PDF if you know the password.
Send the PDF and password through different channels — not in the same email.
When the tool runs in your browser, your file stays on your device for that step and is not uploaded to our servers. Cloud-assisted steps use encrypted transfer; those uploads are deleted within two hours after processing. We do not sell your documents or use them for advertising — see our Privacy Policy.
Yes. Protect PDF is optimized for mobile browsers. Upload from your camera roll or files app, configure options in the side panel, and download the result. Very large files may process faster on desktop.
