Enhance a Scanned Document

Clean up a bad scan — shadows, specks and skew go; the document comes back the same, only cleaner.

FreeNo watermarkOffline

Why is it safe? Many sites upload your file to their servers. Not here: everything happens in your own browser. Your file is never sent to the internet and stored nowhere — because it is never received. It even works offline.

How it works (3 steps)

Add the badly scanned PDF or photo (an already-loaded document is picked up automatically).
Auto mode measures the page and applies only what it needs. Or pick a mode yourself.
Check the Before/After slider, then “Save & download” — you get a 300 DPI document.

Tips

Content never changes — text isn't rewritten, only the image quality improves.
A clean, readable page is left alone: enhancing shouldn't mean damaging.
Faded text is darkened only when it really is faded — already-dark letters aren't thickened.
