I made a tiny (~8MB) photo editor for AI images with batch editing, LUTs, and ComfyUI workflow preservation [Free & Open Source]

I was tired of opening heavy photo editors just to tweak lighting or color-grade a folder of AI generations. So I built TinyLuma - an instant, lightweight photo editor designed specifically for finishing AI artwork and photo sets. No installation required, no subscriptions, and the whole app is only ~8 MB. What’s inside: - All essential controls: Clean sliders for Light (Exposure, Contrast, Highlights, Shadows, Whites, Blacks), Color (Temp, Tint, Vibrance, Saturation), plus Dehaze and natural Film Grain. - Crisp details & texture: Custom Clarity, Texture, and Sharpen sliders to enhance overall sharpness and bring out skin texture, hair strands, and fabric weave without harsh white halos. - Cinematic & Film styles (LUTs): Give your images an analog, cinematic, or vintage film look, or drop in any trending .cube LUT for instant color grading. Includes a smooth intensity slider (0–100%) to blend the effect subtly or strongly. - Doesn't break your ComfyUI workflow: When saving as PNG, it keeps your prompt, seed, and node setup intact. You can drag and drop the edited image right back into ComfyUI. (Optional — you can toggle it off to export completely clean images). - Batch editing & Before/After: Browse your entire folder with the filmstrip at the bottom, compare changes with an interactive Before/After split screen (``), and use "Preset to All" to apply your favorite look to the whole batch at once. - Fast and portable: Starts in under a second, runs smooth at 60 FPS, and barely uses your RAM.
