About this tool
Documents you share often carry author names, software fingerprints and timestamps you did not intend to share. Strip them in one click. Flatten form fields to lock them into the page so reviewers cannot edit them. For password encryption use the Clip PDF native app — encryption keys must be handled on-device for real safety.

Frequently asked questions
Can I password-protect a PDF here?
Not in the web tool. Encryption keys need to live on-device; the native app handles this safely.
What does "flatten" do?
It bakes form-field values into the page so reviewers cannot edit them after the fact.
Will images or text be lost?
No — only metadata fields or form widgets are affected.
Is my file uploaded?
No, pdf-lib runs in your browser.
Free?
Yes.
