Know the boundary
What this tool does—and what it does not.
This tool fills existing fields; it does not create fields on a flat scan. Not all form technologies or field types are supported. XFA, scripted forms and digital-signature fields may not work as expected.
Fill PDF Forms FAQ
Before you start.
Why can I not type into my scanned form?
A scanned page is an image and may have no interactive form fields. This tool is designed for existing AcroForm fields.
Does this support every PDF form?
No. Test the actual document and verify its exported values. Complex, scripted or unsupported forms can require another workflow.
Can I create new form fields?
The current tool fills existing fields; it is not a form-field designer.
How can I test this Pro feature?
See the Founding Beta page for current availability and rules. Beta access requires a verified account and is temporary.
