About this PDF Forms

Create a fillable PDF form from scratch (or add fields to an uploaded PDF) with our pdf forms 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.

When to choose Pdf Forms

This tool is for anyone weighing up the PDF form tools and deciding whether they need to fill, prepare, or process a form.

Worked example: You receive a PDF form and are not sure whether to simply type into it or prepare a fresh fillable version — this overview points you to the right tool for the task.

PDF Forms is the jumping-off point; from here, Fill PDF Form completes an existing form while Create Fillable PDF readies one for others.

  • Decide first whether you are completing a form or building one — that picks your tool.
  • Keep originals and completed copies in separate folders to avoid confusion.

What is the difference between filling and creating a form?

Filling enters data into an existing form; creating prepares a document so that it can be completed by someone else.

Are these form tools free?

Yes, the PDF form tools here are free to use in your browser with no signup required.
