Upload your file and choose a password recipients need to open the PDF. Use a strong unique phrase — PDFTrusted cannot recover lost passwords.
Restrict printing and copying
Under More options, add an owner password and toggle printing, commenting, or form filling. Useful when reviewers may view but must not redistribute content.
Combine with watermark and unlock
Add a Watermark on sensitive drafts before encrypting. If you own the document and know the password, Unlock PDF removes restrictions before flattening or merging.
