Catch blank required fields before submission
Interactive PDF forms can contain text boxes, checkboxes, radio buttons and selection lists. FileFit checks the fields that the PDF exposes and flags required fields that appear empty.
FAQ
Why does my PDF show no fields?
The form may be a scan, flattened PDF, XFA form, or a document whose fields are not standard AcroForm fields.
Does FileFit change my form?
No. This checker is read-only and generates only an optional CSV report.
Are optional blank fields treated as errors?
No. Required blank fields are the main warning. Optional blank fields are listed for review but do not automatically fail the form.

More questions about this tool
Can it check handwritten forms?
No. Handwriting on a scanned page is not an interactive field.
Are optional blank fields a rejection?
Not necessarily. The checker marks them for review rather than automatically failing the whole form.
Can this detect missing attachments?
No. Check the submission instructions for separate required files.
Check interactive form fields before sending a PDF
A required field can be easy to miss in a long interactive PDF. This checker inspects standard AcroForm fields and identifies required fields that appear blank. It also reports optional empty fields so you can decide whether they apply to your situation.
A PDF may look like a form without containing any real interactive fields. Scanned, flattened or XFA-based forms can be invisible to this checker even though they have boxes and lines on screen.
Step-by-step workflow
- Fill the form using a reliable PDF editor, save a copy and open the saved PDF here.
- Click Check Form, then look at field names, types, required flags and statuses.
- If a required field is marked FAIL, open the original editable form, correct it and save again. Review optional blanks instead of filling inapplicable fields blindly.
- Export the optional CSV checklist if you need a record of fields to review. Visually inspect signatures, dates, attachments and the whole document before submission.
Common problems and what to check
| What you notice | What to check |
|---|---|
| Zero interactive fields | The document may be flattened, scanned or an unsupported XFA form. Manual review is necessary. |
| Required checkbox is blank | Check whether it requires a tick or whether a grouped choice must be selected in the original form. |
| All required fields filled | Still verify accuracy, dates, signed pages and required attachments outside the form fields. |
Important limitation
This checker never fills or changes the PDF. It cannot verify truthfulness, identity, legal validity, handwriting, electronic signature acceptance or the completeness of fields not represented as standard AcroForm fields.
