Add text watermarks to protect your PDFs
Add your signature to PDF documents. Draw, type, or upload your signature, then position it anywhere on the page. Perfect for contracts, agreements, and official documents.
Combine multiple PDF files into one document
Control who can open, print, or edit your PDF by setting a password. This tool applies encryption to your document so it cannot be accessed without the correct credentials. You can set an open password (required to view the file) and optionally restrict printing and editing separately.
The tool supports both user passwords (needed to open the document) and owner passwords (which control permissions like printing, copying text, and modifying the file). Encryption is applied client-side, meaning your document and password never leave your browser. The resulting file is compatible with all standard PDF readers.
Protect financial reports, contracts, or strategic plans before sending them over email.
Prevent unauthorized editing of proposals or design files delivered to clients.
Add a password to tax returns, medical records, or other sensitive personal documents stored in the cloud.
Allow viewing and printing but block editing and text extraction for published materials.
The open password is required to view the document at all. The owner password controls what actions (print, edit, copy) are allowed once the document is open.
Yes, if you know the current password. Upload the protected file, enter the existing password, and save it without a new password.
The tool uses standard PDF encryption. For highly sensitive documents, consider additional measures like encrypted email or secure file transfer.
All processing happens directly in your browser. Your files never leave your device and are never uploaded to any server.
