Create Fillable PDF Form

Create Fillable PDF Form turns a flat PDF — a form you typed in Word, a scanned application, a printed sign-up sheet — into one people can fill in on a screen. Open the PDF, pick a field type and drag on the page where the answer goes. Each field gets a name, a hint, a text size, a letter limit and a “required” mark if you want one.

Detect fields does the tedious part for you. It reads each page’s text and drawing and suggests a field wherever a form expects an answer: runs of underscores like “Name: ______”, empty drawn boxes, small squares and ☐ symbols for ticks, lines to write on, and labels such as “Email:” with nothing after them. Each suggestion is named after the words beside it, and you add or skip them one by one or all at once.

The fields are saved as a standard PDF form (AcroForm), the kind Adobe Acrobat Reader, Apple Preview, Chrome, Edge and phone PDF apps fill in. Fields already in the PDF show in green, ready to move, rename, change or delete. Everything happens in your browser; the PDF is never uploaded.

1. Tap “Choose a PDF” and pick the document. Any fields it already has appear in green.
2. Press “Detect fields” to get suggestions, then tap ✓ to add the ones you want, or “Add all”.
3. To add a field by hand, pick its type in the toolbar (Text box, Tick box, Drop-down…) and drag on the page, or just click to drop one.
4. Click a field to name it and set its options in the Field panel. Shift-click several to line them up or make them the same size.
5. Open “All fields” to check the tab order, then press “Save fillable PDF” and “Download fillable PDF”.

• Eight field types: text box, multi-line text, date (with Acrobat’s date-format check), tick box, radio button group, drop-down (optionally with your own answer), list of choices (optionally several), and a real signature field.
• Detect fields: suggestions from underscores, dotted lines, empty boxes, drawn lines, ☐ symbols and labels ending in a colon, named after nearby words.
• Move, resize, duplicate and delete with the mouse, a finger or the keyboard; arrow keys nudge by one point, Shift+arrow by ten.
• Line up several fields by their edges or centres, give them the same width, height or size, or space them evenly.
• A tab order list you can drag, sort by position, or change with the arrow buttons.
• Edits the fields a PDF already has, and leaves untouched ones exactly as they were.
• Undo and redo, page thumbnails and zoom.

• For a set of answers where only one may be picked, use radio buttons: place the first, then press “Add another button to this group” for each other answer.
• Pick “No border” in the action bar when the page already prints its own boxes or lines, so the fields don’t draw a second outline.
• Detect fields needs real text and drawing. A scan is only a picture of the page: draw those fields by hand.
• A signature box is a proper signature field. Acrobat Reader lets people sign it; Preview and browsers show the box and its line. To sign it yourself now, save and carry the form on to Sign PDF.
