Edit and sign contract PDFs — privately
Edit, sign, and redact contract PDFs without uploading them to a third-party server. Built-in PII auto-redact catches accidental leaks.
Editing happens client-side
Contracts are sensitive. FileHook edits in your browser, files are auto-deleted in 2 hours, and we don't run analytics on your document content.
Sign and redact in one tool
Type, draw, or upload a signature. Drag a black box over anything you want redacted — the redacted text is permanently removed on save.
PII auto-detect
One click and we scan for emails, phone numbers, SSNs, and credit card patterns. Useful when sharing a contract excerpt without exposing client details.
FAQ
Is it safe to edit a contract online?+
It depends on the tool. FileHook processes the file in your browser and auto-deletes the short-term storage copy after 2 hours. Your contract never sits on a long-term server.
