Perkforge
How it works
Choose an unencrypted PDF, review the compatibility warning and open a temporary browser copy. Add text, dates, marks, initials, a typed, drawn or uploaded visual signature, then export a new PDF. Nothing is uploaded and no account is required.
Useful to know
The selected source file is never overwritten. This tool does not remove passwords or permissions, verify identity or create an advanced or qualified electronic signature. Editing is expected to invalidate existing digital signatures; keep the original and review the exported copy.
Private by design
Inputs, selected files and results stay inside your browser. Perkforge does not receive the content you process with this tool.
