LUT Generator

LUT Generator is a browser-based colour matching tool for photographers, video editors and creators working with source photographs or SDR video frames. Choose a source image and a reference, compare the colour direction, and refine strength, exposure, contrast and saturation before exporting a result. It can help explore a consistent creative look while preserving an untouched original for comparison. Core matching and previews run locally in the browser. Matching, manual fine-tuning, PNG previews and library presets are free; custom 33- or 65-point .cube exports and successful optional AI requests use credits. Optional AI processing uses a reduced image preview, while export validation sends a colour table. Test exported LUTs in the actual destination editor and check skin tones, neutral surfaces, gradients and highlights rather than relying only on a thumbnail. This is an image-reference creative workflow, not camera calibration, automatic log conversion or a guarantee of identical results across displays. Use images you own or have permission to process and review the current product terms before handling sensitive material.
