About
TextRetouch is a free browser-based editor for making small text corrections in PNG and JPG screenshots. It recognizes Chinese and English text and lets you edit a selected region directly on the image or through a linked text box.
Automatic font matching estimates available fonts, size, weight, color and spacing. Matches are approximate, so review the preview, especially small text, punctuation and numbers. It works best with clear, horizontal text on plain backgrounds. Longer replacements keep the matched font size and show a warning if they cannot fit.
Use it to correct a word in a chat screenshot or update a value in a spreadsheet screenshot. Detected straight grid lines and cell boundaries are protected. Images and recognized text stay in your browser. Supports files up to 10 MB and images up to 20 million pixels, with PNG export at the original image dimensions. PDF editing is not available online.
