FormForge is a free, browser-based tool for turning existing PDFs into fillable forms. 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, then run Form doctor’s 21 AcroForm checks with one-click fixes. The app can generate batches of completed PDFs from CSV data. Signatures can be drawn or typed in a handwritten style, with an optional cryptographic signature at export. PDF processing and drafts stay on the device in the browser; optional analytics require consent and exclude PDF contents and form answers. The installable PWA can work offline after its resources are cached, though opening or reloading the page requires a connection. Exports are AcroForm PDFs that the site says open in several desktop and mobile readers. FormForge does not edit PDF page content or reorder, delete, rotate, or merge pages. There is no fixed file-size or page-count limit, but practical limits depend on device memory.
Who it is for
It suits HR teams, government administrators, legal professionals, small businesses, freelancers, and developers who need fillable PDFs. It is less suited to users who need to edit or rearrange PDF pages.
