Bellevue: Image Viewer & Hover Zoom

Bellevue is a free extension for Chrome, Edge and Firefox that replaces the browser's bare image viewer with one built for looking closely. Zoom with the wheel toward the cursor, click for actual size, drag to pan, rotate, flip, or switch to crisp pixels.

Hold Alt over any thumbnail to see it at full size beside the cursor, or tap Ctrl to open it in the viewer. Bellevue knows where the original file lives on hundreds of sites, so you get the real image, not the preview. On Reddit, X, Pixiv, Instagram and Pinterest it works inside the site itself, and image hosts go straight to the file.
