How to fill a PDF form
- Open the form
Drop a PDF with fillable (AcroForm) fields.
- Fill it in
Every field is listed with the right input: text, checkboxes, radio buttons, dropdowns and lists. The preview updates as you type.
- Download
Save it with editable fields, or tick Flatten so the values become part of the page and cannot be changed.
Frequently asked questions
What if the PDF has no form fields?
The tool tells you. Use Sign PDF instead, which places a signature, initials or a date anywhere on a flat page.
Is my data uploaded?
No. Field values are written into the PDF entirely in your browser.
Can I save a partially filled form?
Yes. Download without flattening and open it again later to continue.
Which fields are supported?
Text, multiline text, checkboxes, radio groups, dropdowns and option lists. Push buttons and signature fields are listed but not editable. XFA-only forms are not supported.
