Questions
How do I make a fillable PDF?
Save your worksheet as a PDF, open it in a PDF form editor, run automatic field detection (Recognize Form in PDFelement), then fix any wrong fields and fill it in once to test. That is the method we used in this guide.
Can I make a fillable PDF for free?
With the PDFelement free trial you can create, fix and fill every field, but the saved file gets a Wondershare PDFelement watermark across the page. The paid version saves without it.
Can I turn a Word or Google Docs worksheet into a fillable PDF?
Yes. Save or download it as a PDF first, then follow the 4 steps above. Our test worksheet was a normal PDF with lines and boxes, not a form.
Why is my answer box only one line?
Multi-line is off. Open the field’s Properties, go to Options and tick Multi-line. Recognize Form also split our big lined box into three one-line fields, so we replaced them with one field.
Do students need special software to fill it in?
They need a PDF reader that supports forms. The file we saved kept every typed answer when we opened it with PDFium, the PDF engine used by Chrome. Test your file on the device your students use before you send it.
