About this Create Fillable PDF

Create a fillable PDF form from scratch (or add fields to an uploaded PDF) with our create fillable pdf tool. Define your fields — text inputs, checkboxes, dropdowns, radio buttons — one per line, and we build a clean PDF form with proper field objects.

The output is a real PDF form (AcroForm), fillable in Adobe Acrobat, Preview, Foxit, Chrome’s built-in PDF viewer, and any other AcroForm-compatible application.

Your privacy is the default. Your selected files are processed in your browser and are not uploaded to our server; all processing happens client-side using pdf-lib for browser-side AcroForm creation, filling, and extraction. Closing the tab clears the working session from this page; downloaded files remain on your device.

This tool is free to use with no signup required. Large files may be limited by your browser’s memory and device performance. Part of PDF Tools Base, a privacy-first collection of 161 PDF utilities. Bookmark the page for next time, and explore related tools in the footer below.
