How to fill out a PDF form online
Fill in forms without printing them
Tax forms, applications, registration sheets, and contracts often arrive as PDFs with fillable fields. Printing them, writing by hand, and scanning them back is slow and produces a messy result. Fill PDF Forms lets you enter the values directly and download a completed copy.
Which forms work
The form opens in the editor with its fields ready to type into. It works with PDFs that contain AcroForm fields, the standard interactive form format:
- Text fields such as names, addresses, and dates.
- Checkboxes, ticked or cleared.
- Dropdowns and radio buttons, set to one of the options the form offers.
Flat forms and scanned paper forms
Some PDFs only look like forms: they are scans or flat exports with no fields inside. For those, type text directly onto the page with the editor’s text tool, or add real fillable fields in the Form tab first.
Saving and printing
Filled values are saved in the PDF and print exactly as shown. You can download a partially completed form and continue later by uploading it again.
Sensitive data stays on your device
Forms hold personal details, from ID numbers to income. Form filling runs entirely in your browser, so neither the form nor the data you type is sent to a server. Once it is complete, you can sign it with the editor’s signature tool before sending it back.
