fastimage.app runs fully in your browser with Web Worker pixel acceleration. Supports color correction, curves, text overlays, masked edits, crop, history, presets, and before/after comparison.

You can also drag and drop an image file anywhere into the editor. Once an image is open, drop additional images to add them as moveable layers.
