Add real, fillable form fields (text, checkbox, options, lists, signature) to a PDF — they work in any PDF reader, not just here.
The fields created here are real PDF form fields (AcroForm) — they open as fillable in Adobe Acrobat, Preview and this site's "Fill form" tool, not just in a preview. The "Signature" field creates a signature field recognized by PDF readers, but this tool doesn't apply any digital signature — use "Sign digitally" or "Fill and sign" for that once it's filled in. Shortcuts: V selects, Delete removes, arrow keys move the selected field.
Choose the document you want to build the form on (for example, a template that's already been designed visually).
Draw text fields, checkboxes, radio buttons, dropdown lists or signature fields wherever you need them, and set each field's name and properties.
The resulting PDF contains real interactive fields that any PDF reader (or the "Fill form" tool) can fill in.
Text fields (single-line or multi-line), checkboxes, radio buttons (one choice among several), dropdown lists and signature fields, among other common form field types.
Yes — the fields you create follow the standard PDF form format (AcroForm), so they work in any compatible PDF reader, including directly in the browser or in programs like Adobe Acrobat Reader.
Depending on each field's options, you can mark certain fields as required, so it's clear which ones must be filled in.
