LUT Generator
Pull the colour grade out of a reference image and export it as a .cube LUT you can reuse across a whole shoot.

How the LUT Generator works
- Optionally upload a reference photo to preview your grade on, or work against the built-in sample image.
- Adjust exposure, contrast, and saturation, white balance (temperature, tint, red/green/blue balance), and shadows, highlights, and vibrance — the before/after preview updates live.
- Pick a LUT size (17, 25, or 33) and download the result as a .cube file, or import an existing .cube to preview and tweak it further.
FAQ
What software can I use the exported .cube file in?
The .cube format is a standard 3D LUT supported by DaVinci Resolve, Adobe Premiere Pro, Photoshop, Lightroom, Final Cut Pro, and most other color grading and photo software.
Can I import an existing LUT to edit it?
Yes. Use the "Import .cube" control to load an existing LUT — it previews immediately on your reference image so you can compare it or use it as a starting point.
What LUT sizes can I export?
Choose 17x17x17, 25x25x25, or 33x33x33. Larger sizes capture finer color transitions at the cost of a bigger file; 33-point is the common choice for professional grading tools.
Does this tool upload my photo anywhere?
No. Any reference image you upload, and the generated LUT itself, are processed entirely in your browser and never leave your device.
Can I use it without an account?
Yes. The page is designed as a no-sign-up browser workspace.
