Upload a scan, a photo, or a flat PDF of a paper form. We straighten it, find every blank line, box, and checkbox, and give you a PDF anyone can type into.
Free with an account. 3 forms a day. No credit card. More free tools: Scan or flatten to PDF
To create a fillable PDF for free, upload a scan, a photo, or a flat PDF of a paper form and select Find the fields. Every blank line, box, and checkbox becomes a field named after the words next to it. Fix anything on the page, then download a PDF anyone can type into. Free with an account: 3 forms a day, up to 5 pages each.

Both turn a paper form into a PDF anyone can type into. The difference is how the fields are found and named.
| Create a Fillable PDF (free) | Builder | |
|---|---|---|
| Finding the fields | Our field detection model | The same model. If it cannot read a page, AI (Claude) finds the fields itself |
| Naming the fields | From the words printed next to each field | AI reads the whole form and names each field, sets its type (date, phone, number) and marks required fields |
| Hard forms | May miss fields or give rough names on dense or unusual layouts | Built for dense forms and unusual layouts |
| Length | Up to 5 pages | Up to 100 pages |
| How often | 3 forms a day | Uses the pages in your plan |
