Frequently Asked Questions

Is my form data sent to a server?

No. All processing happens entirely in your browser. Your form data never leaves your device, making it safe for sensitive information.

What types of form fields are supported?

The tool supports text fields, checkboxes, radio buttons, and dropdown menus. These are the standard interactive field types in PDF forms.

Can I fill forms created in standard PDF readers?

Yes. The tool works with any PDF that contains standard AcroForm fields, including forms created in standard PDF readers, office editors, and other PDF editors.

What if my PDF has no form fields?

If the PDF does not contain interactive form fields, the tool will let you know. You may need to use a PDF editor to add form fields first.

Can I save and edit the filled form later?

Yes. The filled PDF retains its form fields, so you can reopen it and modify the values later in any PDF reader that supports forms.

Does filling the form flatten it?

No. The form fields remain interactive in the downloaded PDF. If you want to flatten the form, use our Flatten PDF tool afterward.

Does this work on my phone?

Yes. The tool runs in any modern browser on any device. Fill forms on your phone or tablet just as easily as on desktop.

Is there a file size limit?

There is no fixed limit. Since processing happens in your browser, the maximum depends on your device's available memory. Most devices handle files up to 100 MB.

Can I fill a PDF form on my phone?

Yes. The tool works on any device with a modern browser. Fill out forms on your phone, tablet, or computer — all processing is local.

Will the filled PDF look the same in all PDF readers?

Yes. The form values are written using standard PDF form APIs, ensuring compatibility with standard PDF readers, Chrome PDF viewer, Preview, and other readers.

Can I fill the same form multiple times with different data?

Yes. Upload the blank form each time to fill it with different values. Each filled copy is independent.

Does this support XFA forms?

This tool supports standard AcroForm fields. XFA forms (used in some legacy form generators forms) may not be fully supported. Most modern PDF forms use AcroForms.
