How to do it

  1. 1.Drop your scanned PDF into MythosPDF. The words on each page become clickable boxes.
  2. 2.Click the first word, Shift+click to extend along the line, then double click or press Enter and type the new text.
  3. 3.Press Enter to apply the change, then Export PDF.

How it works

  • • Words are found from the ink on the page with OCR, not from a scanner's hidden text layer, which often drifts.
  • • The font of the line is identified from the letter shapes, together with size, stroke weight and slant of the photo.
  • • Only the pixels of the words you change are redrawn, in the page's own ink tone, with the surrounding paper grain kept.
  • • The rest of the page image stays byte for byte the same, and any hidden OCR layer is updated so search finds the new words.
  • • Each edit is read back by OCR and checked for ghosts of the old ink before you see it.

Good to know

  • • Changes replace words within one line. A longer replacement moves the rest of that line along; adding new lines or deleting words is not available on scans.
  • • Handwriting, and print in a font that cannot be identified, cannot be redrawn, so the edit is refused.
  • • If the new text would touch a stamp, signature or line, MythosPDF refuses instead of smudging it.
  • • Text is read in English, so other scripts are not editable on scans yet.

Questions people ask

+Can I edit a scanned PDF without converting it?

Yes. MythosPDF edits the scanned page itself. The words you change are redrawn in the page's own font and ink; everything else in the image stays exactly the same.

+Does it use OCR?

Yes, to find the words and their shapes. The page is never turned into a text document, so the scan keeps its look.

+Is the hidden text layer updated?

Yes. If the scan has an OCR layer, like Adobe Scan files, the edited words are updated in it so search finds the new text.

+What if a change cannot be made invisibly?

MythosPDF refuses and tells you why, for example a stamp in the way, handwriting, or a font it could not identify. It never hands back a smudged page.

+Can I just make my scan searchable?

Yes. OCR PDF adds an invisible text layer and leaves the scan untouched.

+Can I edit scanned IDs or certificates?

No. Only change documents you own or may change. Altering official records is fraud.
