FormForge

Turn any PDF into a fillable form in your browser

What is FormForge?

FormForge is a browser-based PDF form builder that turns flat PDFs into fillable forms without uploads, accounts, or installs. You can drop in a PDF, let local AI detect fields, or place them yourself with drag-and-drop tools. It supports text fields, checkboxes, radio buttons, dropdowns, signatures, dates, and numbers. The app also includes live preview, batch creation from CSV, and form repair tools that check AcroForm compatibility. Everything runs on your device, so files stay private and can work offline after loading. It exports standards-compliant fillable PDFs that open in common readers like Adobe Acrobat Reader, Preview, Chrome, and Firefox.
