How to Create a Fillable PDF Form for Free
⏱ Takes less than 1 minute
Turn a static PDF into a form anyone can fill in. PDFredo's free online form builder lets you add text fields, checkboxes, and radio buttons to any page. No account, no watermarks, and your file is deleted from our EU servers after 30 minutes.
Upload your PDF
Drag your PDF or click "Select File". The document loads in the form editor with a field toolbar.

Add fields
Pick Text, Checkbox, Radio, Dropdown, or Signature. Click on the page to place each field and drag to resize.

Configure properties
Set field names, placeholders, required flags, and default values in the side panel. Group radios so only one can be selected.

Download the fillable PDF
Click "Save Form". PDFredo writes the form into the PDF on secure EU servers and offers it for download.

Pro Tips
- Use clear field names. They become default labels in most PDF readers.
- Mark sensitive fields as required so users cannot skip them.
- Use our Flatten tool once the form is filled in to lock the answers permanently.
