How to make a fillable PDF without Acrobat

Written November 11, 2026, from the tools on this site.

Open the PDF here, press Find blanks to turn the blank lines and squares we find into fillable boxes, check and adjust the boxes, and download with “Lock the answers” turned off. The boxes are standard PDF form fields, which most PDF apps let people type into.

Make the form fillable

  1. Open your PDF with the button above.
  2. Place the $1.99 hold when you're ready. Nothing is charged until you download.
  3. Press Find blanks. We add a fillable box above each blank line and in each empty square we find, and tell you how many we added.
  4. Check each box. Drag it to line it up, pull the yellow corner dot to resize it, press Name to rename it, or Delete to remove it.
  5. Add anything we missed. Text box: drag to draw a box people can type in. Checkbox: click to place a tickable box.
  6. Press Download and leave “Lock the answers” off, so the boxes stay fillable.

Get the box sizes right

Make a box about as tall as one line of typing for names, dates and phone numbers. Make it taller than about two lines of text (30 points) for addresses and comments; a box that tall accepts several lines of typing. Leave a little space at the right end of each box so long answers fit.

Test it before you send it

Open the downloaded PDF, type into every box and tick every checkbox. If something is off, open your original PDF again in the same browser within 24 hours, fix it and download again. You won't be charged twice for the same PDF.

Questions about fillable PDFs

Can I start from a Word document?

Yes. In Word, save the document as a PDF (File, Save As, PDF), then open the PDF here. Find blanks looks for printed lines and empty squares, so underscore lines and table cells are worth a try. Draw boxes by hand wherever it misses.

Can I make a scanned paper form fillable?

It can. Find blanks looks at the picture of the page, so a scan with dark, straight lines can work. A crooked or faint scan works less well; draw boxes by hand for those.

Will the boxes work on a phone?

Send a test copy to your own phone and type into each box before you send it out.

How do I name the boxes?

Click a box and press Name. Find blanks names each box after the words next to it, such as “Name” or “Date”, and you can change any of them.
