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 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.

When to choose Create Fillable Pdf

This tool is for people preparing a PDF that others will complete — turning a static form layout into a document ready for data entry.

Worked example: You have a printed-style application laid out in a PDF and want recipients to type into it rather than print and handwrite. Prepare it for on-screen completion before you distribute.

Where the form-filler tools enter data, Create Fillable PDF is about getting a document ready for that step, so use it earlier in the workflow.

  • Lay out clear labels and enough space for answers before preparing the form.
  • Test the prepared file by completing it yourself before sending it out.

Who is this tool for?

It suits anyone distributing a form they want others to complete on a computer rather than by hand.

What should I prepare first?

For an existing PDF, finalise its layout and record the page numbers and field positions in PDF points from the bottom-left. For a blank form, plan within the 595 by 842 point A4 page and choose whether to draw visible labels.
