Luma Image Viewer

Luma turns images opened directly in Chrome into a focused, responsive viewing workspace. Zoom smoothly toward the pointer, drag to pan, fit an image to the window, inspect it at actual size, rotate or flip it, and choose a background that works for the image. The original image URL and browser history stay intact. When you need more than viewing, open Luma's local editor to crop, resize, draw, add arrows or rectangles, and place editable text directly on the image. Export the result as PNG, JPEG, or WebP, or copy a PNG to the clipboard. Highlights: - Smooth pointer-centered wheel zoom - Click-and-drag panning - Fit, actual size, rotation, and flips - Blurred, checkerboard, black, and white backgrounds - Fullscreen, image details, download, and color picker - Full-resolution crop and resize - Freehand, rectangle, proportional arrow, and persistent text annotations - Multi-step undo and redo - PNG, JPEG, and WebP export - Keyboard shortcuts for the complete workflow Privacy is part of the product, not an optional mode. Luma has no analytics, ads, account, tracking, backend, or remote code. Images and edits remain on the device. The only named Chrome permission is storage, used for viewer preferences. Luma activates only when an image is opened directly in its own tab. Although Chrome grants page access so Luma can recognize direct images on different sites, the extension exits immediately on ordinary web pages and does not collect page content or browsing history. Local images work after the user enables Allow access to file URLs on Luma's extension details page.
