Complete any PDF form without printing it

If the form has fillable fields, they appear as boxes you can type into, tick or choose from, exactly where they sit on the page. Your answers are saved into the form's own fields, so the file stays a proper fillable form, which many online portals and HR systems expect. Tick Flatten before saving if you want to lock the answers so they can't be changed.

Many forms are just scanned or printed pages with lines to write on. For those, switch to Add text and click wherever you need to type, type an X in any boxes, and add your signature with Sign. Everything is in the same workspace.

Fill PDF Form: frequently asked questions

The PDF has no fillable fields. It's a flat form. Use Add text to type on the lines, or use Create PDF Form to add real fields.

Yes. Values are written into the fields with their appearance updated, so Acrobat, Preview and browsers show them. Flatten the form if a viewer still shows blank fields.

No. The form is filled and saved in your browser. Nothing you type is sent to us.

Download the PDF without flattening. Open it again later and your answers are still in the fields.

Forms made with Adobe's older XFA technology may not display their fields. Ask the sender for a standard PDF version, or type on the page with Add text.
