BetterViewer

BetterViewer 3.0 replaces your browser's built-in image viewer. Open any image in a tab and it opens in BetterViewer, ready to zoom, annotate and edit. Crop, straighten, adjust colors, use levels & curves, remove backgrounds with AI, extract text (OCR) and scan QR codes. Add arrows, text, emoji, blur and spotlights. Everything runs on your device, and it's free and open source. Available for Chrome, Firefox and Edge, or try the web version with no install.
