Scan a Paper Form, Get a Fillable PDF: OCR Form Detection Explained
· How Formtly turns a scan or phone photo of a paper form into a fillable PDF: what the OCR reads, how fields, checkboxes and tables are detected, and what the result looks like.
From Paper to a Fillable PDF in One Step
Paper forms are the hardest to digitize. There are no fields inside a scan, no metadata, no structure, just ink on a page. Formtly's scan path does two things in one pass:
- OCR (built on AWS Textract) reads every line of text, pairs labels with their blank areas, detects tables, and finds checkboxes
- Field building turns that into real form fields, placed on your original page
The result is a fillable PDF that looks exactly like the document you uploaded, with fields that work in Acrobat, Preview, or any browser. The same conversion can be downloaded as a web form (HTML) if you want to host it.
How It Works
- Go to formtly.com/ocr-scan-to-form
- Upload a scan, a phone photo, or an image-only PDF
- The page is straightened if needed, read by OCR, and every field is placed
- Download the fillable PDF, or the web-form bundle
Multi-page scans become one multi-page PDF; you see the page count and the credit cost before anything runs.
What the OCR Detects
- Labels and their blanks: "Name:", "Date:", "Phone:" are matched to the input area next to or below them
- Checkboxes and radio choices: a "Yes / No" pair becomes a radio group; a list of options becomes checkboxes
- Tables: rows and columns are kept, and every empty cell becomes a field named by its headers
- Signature lines: become signature fields
- Handwritten answers: kept as the field's value when legible; printed text is left as print so it is never mistaken for an answer
What the Result Looks Like
Your page is the background. Fields sit exactly where the blanks and boxes are, lightly tinted so they are easy to find. Nothing is redrawn, so logos, instructions and layout survive untouched. Open it, type, tick, sign, save, send.
Photos from a Phone
Phone photos are fine. The image is straightened and resized before OCR, so sideways or slightly skewed shots still come out upright. Good light and a flat page matter more than resolution.
Accuracy
- Printed text: better than 99% on clean prints
- Handwriting: captured when legible, best treated as a draft to check
- Field placement: automatic and usually right; open the PDF once before sending it out
Best Use Cases
- Medical offices: intake, insurance and consent forms that only exist on paper
- Government: applications and permits issued as scans or faxes
- Schools: enrollment forms, permission slips, evaluation sheets
- Field work: inspection checklists and daily reports photographed on site
- HR: legacy onboarding packets
