Protect and Clean PDF Files
Security tools either protect a document (passwords and permissions) or clean it before sharing (metadata, hidden content, editable form fields). They run in your browser, so documents and passwords stay on your device.
None of these tools can open a PDF without its password; decryption needs the correct password.
Password Protect a PDF
Add a password to a PDF with 256-bit AES encryption and choose whether printing, copying or editing is allowed. Encryption runs in your browser.
Remove PDF Hidden Data
Remove hidden data from PDFs online. Clean metadata, scripts, and sensitive information to protect privacy and secure your documents.
Remove a Password from a PDF
Remove the open password and encryption from a PDF when you know the password. Unlocking runs in your browser, so the file and password stay on your device.
non-editable PDF
Flatten PDF forms and annotations online. Make content non-editable to secure layout, preserve data, and prepare documents for sharing.
Remove Metadata from a PDF
Clear the author, title, subject, keywords, creator, producer and dates stored in a PDF before you share it. Free standard tool that runs in your browser.
Change PDF Permissions
Modify PDF permissions online. Control printing, copying, and editing access to secure and manage your PDF documents easily.
