How to fill a PDF form

Upload a PDF that contains interactive form fields. The tool detects all fields automatically and displays them. Fill in the values, then click Save to download a flattened PDF with your entries permanently embedded.

What types of fields are supported?

  • Text fields — any field where you type a value.
  • Checkboxes — tick or untick.
  • Dropdowns — select from a list of options.

What does flattening mean?

Flattening merges the form fields into the page content, making the values permanent and the form no longer editable. This is the standard way to submit a filled PDF form.

Privacy

All processing is in your browser. No file is sent to any server.

Frequently asked questions

Common questions about this tool.

What if no fields are detected?

The PDF may not have interactive form fields — it could be a scanned form or a static document. This tool cannot fill scanned forms.

Can I save and come back later?

No — download the filled form immediately. If you close the tab, your entries are lost.

Can the recipient still edit the form?

No — the output is flattened, meaning the fields are merged into the page and cannot be changed.
