Frequently Asked Questions

PDF Forms FAQs

Answers to the questions people ask most about using PDF Forms.

How do I fill out a PDF form online?

Upload the fillable PDF to PDF Forms on MyPDFMate. It detects the form's fields, you type your answers, and you download the completed PDF.

Can I fill a PDF form for free?

Yes. No sign-up, no watermark and no limit.

How do I know if my PDF form is fillable?

Upload it: PDF Forms lists every field it finds. If it finds none, the form is flat, meaning it just looks like a form on the page.

How do I fill in a PDF that isn't fillable?

Use Edit PDF to type text anywhere on the page, such as next to each label.

Can I fill in checkboxes and dropdowns?

PDF Forms currently fills text fields. Checkboxes, radio buttons and dropdowns are left as they are.

Can the form still be edited after I fill it?

No. The completed form is flattened, so your answers become part of the page. That's ideal for submitting a final copy; keep the blank original if you need to fill it again.

How do I fill out a PDF form without Adobe?

Use PDF Forms in your browser. Chrome, Edge and Mac Preview can also fill most fillable forms directly.

Why can't I fill out a PDF form?

The form may be flat (no fields), restricted by security settings, or an older dynamic (XFA) form that only opens properly in Adobe Reader.

How do I fill out a PDF form and send it without printing?

Fill it in PDF Forms, download the completed PDF and attach it to your email or upload it to the portal. There's no need to print, write and scan.

How do I fill in a PDF form on my phone?

Save the form to your phone (for example, from the email it came in), open PDF Forms in Safari or Chrome, pick the file and type your answers. Then download the completed PDF and share it.

Can I sign a PDF form after filling it?

Yes. Fill it here, then add your signature with Sign PDF.

Is my form data private?

Yes. The form is filled in your browser, and neither the file nor your answers are sent to a server.
