Frequently Asked Questions
How do I fill out a PDF form online?
Upload the PDF; its fields are listed for you to fill. Click Fill to download the completed form.
Which kinds of fields are supported?
Text boxes, multi-line text, checkboxes, dropdowns, list boxes and radio buttons.
Why does it say my PDF has no form fields?
The PDF isn’t a fillable form — its boxes are just drawn lines. Use Edit PDF to type text onto it instead.
What does flattening a form do?
It turns your answers into regular page content so they can’t be changed.
Should I flatten a form before sending it?
Flatten if you want the answers locked; leave it unflattened if someone else must still edit it.
Can I sign the form too?
Fill it here, then use Sign PDF to add your signature.
How do I fill a PDF form on iPhone or Android?
Open this page in your mobile browser and fill the fields there.
Will my answers be saved if I close the page?
No — download the filled PDF before leaving.
Can I fill a protected form?
If it has an opening password, unlock it first with Unlock PDF.
Does the Fill PDF Form tool store my form data?
No, the PDF and your answers are deleted immediately after processing.
