Fill PDF Form

Choose a PDF that has a fillable form (an application, a W-9, an intake sheet) and this tool reads its actual form fields, lets you fill them in right here, and hands back a completed PDF. No account, and the file never leaves your browser.

Your file is processed entirely in your browser. It is never uploaded to any server.

How to fill a PDF form: step by step

  1. Choose a PDF above. If it has real fillable fields (an AcroForm), they'll list automatically below the file picker.
  2. Fill in each field: text boxes, checkboxes, radio buttons, and dropdowns all render as the appropriate input.
  3. Click Fill & Download to save the completed PDF.
  4. Open the download to confirm every value landed where you expected.
  5. If no fields appear, the PDF likely doesn't have real form fields; see the FAQ below for what to do instead.

What counts as a "fillable" PDF

Some PDFs look like forms, with ruled boxes and underlined blanks, but are just flat text and images with no actual data fields behind them; those can't be auto-detected by any tool, this one included. A genuinely fillable PDF has an AcroForm: real named fields a program can read and set, the same technology Adobe Acrobat and Word's own "Prepare Form" feature create. This tool detects and fills exactly that kind of field.

Frequently Asked Questions

No fields showed up: what do I do?

That means the PDF doesn't have real form fields, just the visual appearance of a form. Convert it with the PDF to Word tool instead, type your answers directly into the text, then convert back or print to PDF.

Can the recipient still edit the fields after I fill them in?

Yes, this tool fills the fields but doesn't flatten or lock them, so anyone opening the PDF in a compatible viewer can still change your answers, the same as if you'd filled it in Acrobat without flattening.

Does this work with checkboxes and dropdowns, or just text fields?

All of the above: text fields, checkboxes, radio button groups, and dropdown/list fields each render as the matching input type automatically.

Can I add a signature?

Not a drawn or digital signature: this tool fills standard form fields (text, checkbox, radio, dropdown) only. For signature fields specifically, use a dedicated e-signature tool.

Is this free, unlike similar tools that gate form-filling behind an account?

Yes, no signup, no watermark, no page limit. It runs with the same open-source PDF library this whole site uses, entirely in your browser.
