How to fill a PDF form online, no fields needed

Quick answer: To fill a PDF form online, upload it to PDFPro, open Forms and choose Fill mode, type into the fields and tick the boxes, then apply changes and download. If the PDF has no clickable fields, use the Text tool to type anywhere and the Sign menu for check marks and the date.

PDF forms come in two kinds, and they need different approaches. Knowing which one you have saves a lot of time.

How do I know if my PDF form is fillable?

Open the PDF and click a blank box. If a cursor appears and you can type, the PDF has real form fields. If nothing happens, or the form is a photo or print-to-PDF export, it is a flat form. Scanned forms are always flat.

How do I fill a fillable PDF form?

1. Upload the form to Fill PDF form.
2. Open Forms and choose Fill mode.
3. Click each field and type. Tick checkboxes, pick radio buttons and choose from drop-downs.
4. Add your signature if the form asks for one (see below).
5. Press Apply changes and download.

Fields you filled keep their entries in the downloaded PDF.

How do I fill a PDF with no form fields?

Flat forms have nothing to click, but you can still complete them:

1. Upload the PDF.
2. Choose the Text tool, click where the answer goes and type. Pick a font size that fits the line.
3. Open the Sign menu for the quick marks: check, cross, dot and today’s date. Click once per mark and press Esc when finished.
4. Zoom in and nudge anything that sits on a line instead of above it.
5. Apply changes and download.

This also works on scanned forms. For better placement, read Add text to PDF for font, size and colour options.

How do I sign the form in the same session?

Open the Sign menu, create a signature by drawing, typing or uploading an image, and click where it belongs. It is an image of your signature, so it counts as a simple electronic signature. Certificate-based digital signatures are not supported. The full steps are in How to sign a PDF online and on the Sign PDF page.

Which method fits my form?

Your form	Best approach
Clickable fields	Forms → Fill mode
No fields, clean digital PDF	Text tool plus quick marks
Scanned or photographed	Text tool, whiteout if you need to cover something
You want others to fill it	Create fields first

Can I make my own fillable form?

Yes. Use Create PDF form or Forms → Add new form fields. You can add text fields, checkboxes, radio buttons, drop-downs and signature boxes, and set the tab order so people move through them sensibly. Detect fields can suggest likely blanks on a flat page, and you can fix or delete any it gets wrong. You can also publish a link for others to fill the form in.

Tips for a clean result

• Fill the form from top to bottom, then review the whole page.
• Use the same font size across a section so answers line up.
• Use the date quick mark instead of typing, to avoid format errors.
• Zoom in and check long answers do not run past the edge of the box.
• Download and open the file in another viewer to confirm all entries appear.

What if I made a mistake?

Press Undo (Ctrl+Z) before you apply changes. After you download, fix it by uploading the downloaded file again and editing it. Your original is never altered, so keep it as a clean copy.

Is it free and private?

Yes. Filling and downloading forms up to 50 MB is free, with no sign up or login. Your file is deleted from our servers automatically after 2 hours. Forms often contain personal data, so download the result, and avoid using shared computers for sensitive documents.

For background on how interactive forms are defined in PDF files, the PDF Association publishes information about the standard.
