Fix a typo in a scanner apps PDF
A single wrong letter is the most common reason to edit a PDF. Fixing it should change that letter and nothing else. This works on the PDF scanner apps exported, so you do not need the original file.

How scanner apps writes PDFs
- • Scans are images of the page, sometimes with a hidden text layer from OCR.
- • The visible text is pixels, not letters.
What that means when you fix a typo
- • Scanned pages are pictures of text. Use OCR PDF to make them searchable; typing into a scan is a separate, image based process.
- • scanner apps often uses fonts that are not freely available. Letters already in the PDF are reused exactly; for a letter it never used, MythosPDF asks before using the closest open font and tells you which one.
What happens to the rest of the page
- • Only the words you touch are rewritten. The rest of the line keeps its exact position and spacing.
- • If the correct letter was never used anywhere in the file, MythosPDF loads the complete font so the letter matches.
Questions people ask
+Will fixing one letter move the rest of the paragraph?
Only if the word gets wider or narrower. Then the words after it on that line shift by exactly the difference, and nothing else moves.
+Is it better to edit in scanner apps?
If you have the original scanner apps file and a lot to change, yes. For quick changes to the PDF itself, editing the PDF is faster and keeps it exactly as sent.
