How WhatsApp document scan scans

  • • WhatsApp can scan a document with the camera and send it as a PDF.
  • • Phone scanners photograph the page, straighten and crop it, and save the image into a PDF.
  • • Photos carry perspective, uneven light and JPEG compression, and some apps add a hidden OCR text layer.
  • • Camera foreshortening is fitted as a horizontal scale on each line, and the paper grain around the word is kept, so the new word sits in the photo like the old one.

Questions people ask

+Can I add a new dish?

Adding new lines is not available on scans; you can replace an existing line's words.

+What if a word cannot be changed invisibly?

You get the exact reason, such as a stamp in the way or a font that could not be identified, instead of a smudged page.
