LUT Generator is a free, browser-based LUT generator that turns a reference image into a downloadable .cube LUT file for color grading in video and photo editing software.
What is LUT Generator?
LUT Generator is a free online tool that creates LUT (Look-Up Table) files from two images. It takes a flat or ungraded frame as the source and a graded reference still whose colors you want to copy, then generates a .cube LUT you can download and use in editing software. It runs in the browser—no installation required.
Key Features
- Two-image LUT creation — Accepts a "Your frame" slot for the flat or ungraded shot you want to transform and a "Reference look" slot for the graded still whose colors you want to copy.
- Downloadable .cube output — Generates a .cube LUT file that can be imported into editing software for reuse.
- Browser-based, no install — Runs online; you add images by drag-and-drop or clicking, with no desktop application required.
- Fast generation — Create your own LUTs from an image in seconds.
- Free to use — Free online LUT generator.
- Drag-and-drop or click upload — Both image slots support dropping an image or clicking to select a file.
Who should use LUT Generator?
- Video editors and colorists — quickly build a custom LUT that matches a reference grade, then apply it to footage in an NLE or grading app.
- Photographers — copy the color look from a graded still onto ungraded photos by exporting a .cube LUT for use in photo editors that support LUTs.
- Content creators — create a reusable color preset from a reference image to keep a consistent look across YouTube videos, reels, or other projects.
- Beginner color graders — generate a LUT without manually building curves or color wheels, using two images as the only input.
What can you do with LUT Generator?
- Match a film or creator look: Upload an ungraded frame and a still from a movie or creator whose color grade you like, then download a .cube LUT to apply that look to your own footage.
- Build a reusable LUT from a photo: Use a graded photo as the reference and a flat frame as the source to produce a LUT you can save and reuse across multiple clips or images.
- Create a consistent color base: Generate a LUT once, then apply it in editing software to keep color consistent across a series of shots or a photo set.
How does LUT Generator work?
LUT Generator uses two image inputs: a "Your frame" slot for the flat or ungraded shot you want to transform, and a "Reference look" slot for the graded still whose colors you want to copy. After you add both images, the tool generates a LUT that you can download as a .cube file for use in your editing software.
