Summary

FormForge is a free browser-based PDF form builder for adding fillable fields to existing PDFs. Its AI detects fields in flat PDFs and scans, with detection running locally in the browser through WebAssembly. Users can add text, checkbox, radio button, dropdown, signature, date, and number fields. Form doctor performs 21 AcroForm checks and offers one-click fixes, while CSV input can be used to create batches of filled PDFs. Signatures can be drawn or typed in a handwritten style, and users can optionally add a cryptographic signature when exporting. PDF processing and drafts stay on the device in the browser. The installable PWA can work offline after resources are cached, but opening or reloading the page requires a connection. FormForge exports AcroForm PDFs and ZIPs of filled PDFs. It does not edit underlying page content or reorder, delete, rotate, or merge pages. There is no fixed page-count or file-size limit, though practical limits depend on available device memory. The free plan requires no account or credit card and has no page limit or watermark.

Who it is for

FormForge suits HR and recruiting teams, government administrators, legal professionals, small businesses, freelancers, and developers who need fillable PDF forms. It may also fit users who want to process forms in a browser while keeping drafts on their device.
