Got a LUT you love and no app to use it? Gotcha.
Drop in an image and a LUT. The grade happens right here in the tab. No upload, no server, no account, no subscription.
Formats accepted are .cube (1D and 3D), Autodesk .3dl, Cinespace .csp, HALD CLUT .png, and Lightroom presets as .xmp or .lrtemplate.
Lightroom presets are a close approximation. White balance, exposure, contrast, tone curves, HSL, vibrance, saturation, colour grading and embedded profile tables carry over. Highlights and shadows carry over only in part, since Lightroom applies them edge by edge and a LUT cannot. Clarity, texture, dehaze, grain, vignette and masks do not carry over at all. Those depend on where a pixel sits, not what colour it is.
Then tweak. Strength dials the LUT in or out. Light, Colour and Effects sliders run on top of it, in that order. Type a number, nudge with arrow keys (Shift for ×10), or hit to reset one control.
Read the scheme. Under the image, one swatch per hue family present in the graded result, plus darks, lights and neutrals, each with its hex and share of the frame. Hover a swatch to copy it, or take the whole set as comma-separated hex or an Adobe .ase swatch file.
Check your work. Press and hold the image, or hold \, to peek at the original. Compare opens a split you can drag across.
Et voilà! Download a full-resolution PNG, named after your image with the suffix -LHK. Or export a .cube that bakes the LUT and your Light and Colour settings into one file, ready for Resolve, Premiere, Photoshop or this page. Grain, vignette and sharpen stay out of it, since a LUT cannot hold them.
Your image, LUT and settings are kept in this browser so a reload does not lose them. Nothing is sent anywhere. Enjoy!
