Make a scanned form fillable
An old paper form, scanned once, made typeable for good.
The form that gets photocopied every year and has no original file left is a common problem. A scan of it is just a picture: there is no text to read and no lines to measure, so field detection has nothing to work with. The fix is to give the scan a text layer first with OCR, which recognises the words and the rules on the page. After that the form behaves like any other PDF and the blanks can be turned into fields.
How to make a scanned form fillable
- 1
Scan the form cleanly
Straight, in good light, at a decent resolution. A crooked scan reads badly and detects badly.
- 2
Run OCR on it
OCR PDF adds an invisible text layer without changing how the page looks. It runs in your browser like everything else here.
- 3
Add the fields
Bring the OCR version here. The blanks are found, named from the recognised labels, and saved as real form fields.
Why rescuing the old form is worth it
Rebuilding a form nobody has the original of means retyping it and hoping the wording is right. Scanning it once and adding fields keeps the exact document everyone already recognises.
Start with the text layer
OCR adds a searchable text layer to a scan without changing how it looks.
Frequently asked questions
Why does it say my page looks scanned?+
Because the page has no text at all, which means there is nothing to read the labels from. That message is telling you to run OCR first rather than letting you download an empty result.
How good does the scan need to be?+
Good enough for OCR to read the labels. Straight, evenly lit and at 300 dpi is comfortable. A phone photo at an angle usually is not.
Will the field names be right?+
They are only as good as the OCR. Check them in the review step and rename any that came out garbled before you save.
Does the scan get uploaded for OCR?+
No. OCR runs in your browser too, which is unusual and is the reason a form with personal details on it can be processed here at all.
