FormForge

FormForge is a PDF form editor that runs entirely in your browser. Open any PDF and place text, checkbox, radio, dropdown, signature, date and number fields on the page, or let a neural network running locally on your device detect the fields on a flat form. Exports are standard AcroForm PDFs that open in Adobe Reader, macOS Preview, Chrome and Firefox. It also fills and flattens forms, mail-merges a CSV into a ZIP of personalised PDFs, runs 21 AcroForm compliance checks with 16 one-click fixes, and can seal an export with a certificate whose private key never leaves the device. Built for HR, public administration, legal practices, small businesses and developers who need AcroForm fixtures. Nothing is uploaded and no account is needed.
