About this PDF Forms
Create a fillable PDF form from scratch (or add fields to an uploaded PDF) with our pdf forms tool. Define text, checkbox, dropdown and radio fields with one comma-separated record per line: type,name,page,x,y,width,height. Coordinates and dimensions use PDF points from the bottom-left; page numbering starts at 1. For dropdown or radio fields, append a comma and pipe-separated options. Use distinct names for different fields and leave room below a radio group for its stacked options.
The output is a PDF form (AcroForm). Blank mode creates A4 pages sized 595 by 842 PDF points, up to the highest page number in the definitions. With an uploaded PDF, choose page numbers that exist in that document. Download the result and check field positions and behavior in the PDF viewer your recipients will use.
Your privacy is the default. Your selected files are processed in your browser and are not uploaded to our server; field creation happens client-side using pdf-lib. 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.
