Tips

1. Check if the form is fillable — if fields don't highlight when you click, it's a flat (non-fillable) PDF. Use PDF Annotate to type on it instead
2. Save before closing — your filled data isn't saved until you download
3. Flatten after filling — use Flatten PDF to lock your entries so they can't be changed
4. Print-ready — the downloaded form prints with all your entries filled in

Frequently Asked Questions

Is my data secure?

Yes — the form is filled in your browser. The completed form is processed securely and deleted after download.
