Fillable PDF forms, free: filling them and making them.

Filling a PDF form is free and takes a 4.6 MB reader. Creating a fillable form is also free, with LibreOffice Writer's form controls. Neither needs a subscription or an upload. Here are both walkthroughs.

Filling

How to fill out a PDF form for free

  1. Open the form in No Bloat PDF. Real form fields light up as you click: type in text boxes, tick check boxes, pick from dropdowns.
  2. No real fields? It is a scan. Plenty of "forms" are just pictures of forms. Use the text annotation tool to type your answers over the lines. Same result, nobody will know the difference.
  3. Sign it if needed. The signature tool handles that in the same sitting: one-minute walkthrough here.
  4. Save the filled copy. Everything happened on your machine. The app makes zero network calls, so the form with your personal details in it could not have gone anywhere.
Creating

How to create a fillable PDF form at no charge

The best free form-authoring tool is not a PDF tool at all. LibreOffice Writer (free, open source, offline) exports genuine fillable PDFs:

  1. Design the document in Writer like any other: labels, sections, instructions, your logo.
  2. Turn on Design Mode in the Form menu, then insert text boxes, check boxes, list boxes, and option buttons where the answers should go.
  3. Export As, Export as PDF, and keep Create PDF form checked in the export dialog.
  4. Test the result in No Bloat PDF: fill a few fields, save a copy, confirm it behaves. What you made is a standard AcroForm PDF that works in every mainstream reader.

Skip the "free online form builder" sites for anything real: your form templates and your respondents' filled data both deserve better than a mystery server, and the offline route above is genuinely free with no page limits or watermarks.

Honest note

The limits, stated plainly

No Bloat PDF fills and signs forms but does not author them; authoring is an editing feature and it stays a viewer on purpose. And one format caveat: XFA forms, an Adobe-specific enterprise format some government and insurance portals use, need Adobe's own tools on both ends. If a portal says "requires Adobe Acrobat," that is the one time it means it. Everything else on this page is the open standard, free end to end.

Forms filled, signed, and never uploaded.
