Fillable vs. scanned forms
This tool works with fillable PDF forms, which contain real form fields. A scanned paper form is just an image, so it has no fields to fill; for those, use our Add Watermark or Sign PDF tools to place text and signatures.
What does "flatten" mean?
Flattening turns the filled fields into normal page content, so the answers can no longer be changed and display the same in every PDF reader. Flatten before sending a final copy; keep an unflattened copy if you may need to edit it.
Frequently asked questions
Why does it say my PDF has no fields?
The form is not fillable; it is probably a scan or was exported without form fields.
Which characters can I type?
Latin letters, numbers and common symbols, including accents. Other alphabets may not display in the standard PDF fonts used by most forms.
Is it safe for forms with personal details?
Yes. The PDF is filled in your browser and is never uploaded.
