Frequently asked Questions

How do I modify fillable fields in a PDF?

Open the PDF in Xodo's online editor. Select the field and adjust its size, type, value, or formatting from the properties panel.

How can I edit a fillable PDF for free online?

Upload your form to Xodo Web. You can add or remove fields in your browser for free.

What’s the difference between editing the form structure vs. filling it out?

Editing the structure changes how the form works. You add, move, or adjust fields. Filling out the form only adds your responses. The layout stays the same.

Why can’t I edit a fillable PDF?

The file might be locked, flattened, or built from a scan. Your viewer may also only support filling, not editing. Uploading the PDF to Xodo usually solves this, because you can rebuild fields even if the original ones can’t be edited.

Can I edit forms that are not already fillable?

Yes. You can add fields to scanned or static PDFs by placing text boxes, checkboxes, dropdowns, and more.
