About the tool

What is Fill PDF Form?

Many official PDFs are fillable: tax forms like the W-9 and W-4, job and rental applications, school forms and medical intake sheets. This tool finds every text field, checkbox, radio button and drop-down list and lets you complete them without printing anything. Answers you type on the page appear exactly where the form expects them.

Choose “Flatten the form” if the recipient should not be able to change your answers; leave it off to keep the fields editable. If a form has no fillable fields, for example a scanned paper form, use Add Text to PDF to type anywhere on the page, and Sign PDF to add your signature.

Your files stay with you. This tool works inside your browser tab. Nothing you select is uploaded, stored or seen by us.

FAQ

Frequently asked questions

How do I know if my PDF is fillable?

Upload it. We list every fillable field we find. If there are none, the form is “flat” and you can type on it with Add Text to PDF instead.

Can I fill out IRS forms like the W-9?

Yes. Current IRS forms such as the W-9 and W-4 are fillable PDFs. Download the latest version from irs.gov, fill it here, then sign and send it as instructed.

What does flattening a form do?

It turns your answers into regular page content, so they display the same everywhere and can no longer be edited as fields.

Are my answers sent anywhere?

No. The form is filled in your browser, so personal details such as your SSN or address never leave your device.
