LUT Generator

Start with a source photo and a reference showing your desired colors. The LUT generator accepts JPEG, PNG and WebP images up to 20 MB and 24 megapixels each. Use a source that represents the material you plan to grade, so the preview helps you make a useful decision.

Choose similar lighting and subject matter, with visible detail in shadows and highlights. For image to LUT matching, a balanced reference usually gives you a more useful starting point than a heavily filtered image. Compare skin tones or neutral objects, then reduce strength if the borrowed color style overwhelms your source.

No. You can approximate the global color style, but you cannot extract a LUT from an image and recover the original editing decisions exactly. The LUT generator creates a new transform from your source and reference. Grain, blur, masks and selective retouching are not stored in a 3D LUT.

Upload an SDR H.264 MP4 up to 100 MB and 60 seconds. Choose a frame that represents the clip, match it to your reference, then refine the preview. Export a .cube or PNG from the LUT generator; apply the LUT and render the finished video in your editing software.

Normalize camera Log, HLG or PQ material to Rec.709 in your editor first. The online LUT creator’s Rec.709 option produces a Gamma 2.4 creative look for normalized SDR footage. It is not a camera conversion LUT, and choosing that option does not automatically normalize an uploaded Log image.

Start with 33 points when you want a smaller file and broad editor support. Both grid options in this LUT generator sample the same color transform; 65 points gives a denser table and a larger file. Check your editor’s import requirements rather than assuming a larger grid always improves the look.

Import the downloaded file as a 3D LUT or custom look in your editor. Match the color-space settings used for export and compare against your PNG preview. If the imported grade differs, check input tags, gamma and interpolation. The software logos above link to vendor information about LUT support.

The core LUT generator matches references locally in your browser. If you are looking for an AI LUT generator, the optional assistant adds a different role: it suggests adjustments from your request and reduced previews. Review the suggested colors yourself; AI assistance does not guarantee an exact reference match.

Local matching keeps original photos and videos in your browser. A custom export sends the .cube text for server verification. If you request AI assistance, reduced previews up to 768px, adjustment parameters and your text are sent to the AI provider; original files, filenames and EXIF are not sent.

Try a sample or add your own images to the online LUT creator. Matching, fine-tuning, PNG downloads and library presets are free. Custom workbench exports and successful AI requests use credits. Check the pricing page for allowances and trial-pack details; real payments are not active yet.
