Color-grade Images
# Apply a LUT to a Photo Online — Color Grade with Any .cube File Apply a LUT to a photo online: upload the image, add any 3D `.cube` file — a look from the catalog or one you exported from DaVinci Resolve, Premiere, or any grading tool — and download the graded result. An **intensity** slider blends the graded picture over the original, so 1 is the full look and 0.5 is half strength. The killer feature is consistency with video: the **same LUT produces the same colors as the video LUT tool**. Grade a thumbnail with the same `.cube` as its video and the still matches the footage exactly — the thing manual filter apps can't promise. ## How to apply a LUT to an image 1. **Upload** the photo (JPG, PNG, WebP — even an animated GIF, which grades every frame). 2. **Add the LUT** — any 3D `.cube` file up to 8 MB. 3. **Set intensity** and download; the output keeps your input format. ## FAQ **What is a LUT?** A look-up table — a portable color transform used across the film industry. `.cube` is the standard file format. **Where do I get LUTs?** Use the built-in catalog looks, buy or download from creators, export from a grading tool — or fit one from reference footage with the LUT extractor. **Can I make the effect subtler?** Yes — intensity 0.5 blends the grade at half strength over the original. **Why did my HEIC come back as PNG?** HEIC and AVIF inputs return PNG; all other formats keep their own.
