Fill In a PDF Form

Open a fillable PDF, type straight into its real fields, and optionally flatten it so the answers cannot be changed afterwards.

Filling a PDF form online normally means one of three things: a desktop application you do not have, a monthly subscription for a handful of forms a year, or a website that wants your tax return or medical form uploaded to its servers first.

This tool reads the actual form structure out of the file and builds an input for every field it finds — text boxes, checkboxes, radio buttons and dropdowns. When you are done you can flatten the document, which bakes the answers into the page so the file can be printed or emailed without the fields shifting or being altered.

How to fill in a pdf form

  1. Add your PDFDrop a PDF that contains form fields. The tool lists every field it finds, with the label taken from the form itself.
  2. Type your answersFill in the text boxes, tick the check boxes and pick from the dropdowns. Nothing is submitted anywhere as you type.
  3. Choose whether to flattenFlattening locks the answers into the page so the document can no longer be edited. Leave it off if the recipient needs to add more.
  4. Save the filled PDFThe completed document is written locally and downloads straight to your device.

Frequently asked questions

What if my PDF has no form fields?
A PDF that was scanned or exported as an image has no fillable fields — there is nothing for the tool to type into. Use the Watermark PDF tool or the Sign PDF tool to place text or a signature on the page instead.
What does flattening do?
Flattening converts the form fields into ordinary page content. The answers stay visible and printable but can no longer be typed into or changed.
Will my answers be saved between sessions?
No. Everything exists in the browser tab you are working in. Close the tab and the data is gone, which is exactly why nothing needs to be trusted to a server.
Can I fill a form that is password-protected?
No. Encrypted PDFs cannot be opened by browser-side tooling. Remove the password first.
Do the font and layout change?
Text is drawn with an embedded standard font sized to the field, so the layout is preserved. Fields that specify a particular font fall back to the closest standard equivalent.
