★ LUT Color Grading
Free online LUT color grading tool
Upload a photo, pick a color look — or upload your own .cube LUT file — and download the graded result. Runs entirely in your browser.
Upload an image to start applying a color LUT
Want the teal-and-orange blockbuster look, a warm cinematic tone, or a faded vintage-film feel on a photo or thumbnail — without installing Premiere or DaVinci Resolve? This tool applies a real 3D LUT color transform directly in your browser, with 5 built-in looks to start from, or your own .cube LUT file if you already have one you like.
Everything is processed on your device's canvas — your photo is never uploaded anywhere — and you can dial the effect intensity up or down before downloading the result as a PNG.
Why use this LUT tool?
Real 3D LUT math
Uses proper trilinear interpolation on a real 3D lookup table — the same technique professional color grading tools use.
Bring your own .cube
Already have a favorite LUT from DaVinci Resolve or elsewhere? Upload the .cube file directly.
100% private
Your photo is processed on your own device's canvas — nothing is uploaded to a server.
Frequently asked questions
What is a LUT?
A LUT (Look-Up Table) is a 3D color mapping that transforms every color in an image to a new one, used to create consistent, professional color looks — the same technology used in film and video color grading.
Can I use my own .cube file?
Yes. Click "Upload Your Own .cube" and select a standard .cube LUT file — the same format exported by DaVinci Resolve, Premiere, and Lightroom.
Does this work on video?
Not yet — this tool currently applies LUTs to still images (photos, thumbnails, cover art). Applying a LUT frame-by-frame to video requires much heavier browser processing, which we may add later.
Is my photo uploaded anywhere?
No. The color transform runs entirely on your device using your browser's Canvas — nothing is sent to a server.
