LuttieLUT Converter
Move a look between Lightroom and your video editor. Convert an .xmp profile to a .cube LUT, a .cube to an .xmp profile or a .3dl, or turn any preset into a .cube. See the result on a sample photo or your own picture before you download it.
This reads the 3D colour table stored inside a profile. Profiles built from a LUT hold nothing else, so they convert exactly. A develop preset (.xmp with slider settings and no table) can't be read this way.

Which conversion you need
| You have | You want | Use |
|---|---|---|
| A Lightroom profile made from a LUT (.xmp) | A .cube for Premiere, Resolve, Final Cut or CapCut | .xmp to .cube |
| A Lightroom develop preset (.xmp, sliders) | A .cube for video | Any preset to .cube |
| A .cube LUT | A profile for Lightroom or Camera Raw | .cube to .xmp |
| A .cube LUT | A .3dl for Flame, Lustre or Avid | .cube to .3dl |
| A 65-point .cube | A 33-point or 17-point version | .cube at another size |
| A preset from another photo app | A .cube | Any preset to .cube |
Why an .xmp is sometimes a LUT and sometimes not
Lightroom uses the .xmp extension for two different things. A preset is a list of slider positions. A profilecan carry a full 3D colour table, which is a LUT in everything but name, and that is how LUT sellers ship looks for Lightroom. This tool reads the table when there is one and tells you when there isn't.
Adobe's own profiles also hold a table, usually defined in Adobe RGB. The converter takes that into account, so the .cube it writes is meant for ordinary Rec.709 or sRGB footage. Other settings in the same file, such as a tone curve, are not part of the table and are left out.
The reference picture method
The reference picture is a 512 by 512 image containing 262,144 colours laid out in order, known as a HALD image. Whatever an editor does to those colours is the look. Reading them back in the same order gives a 64-point LUT, which the tool resamples to the size you pick. It works for any app that can open and export a PNG, not only Lightroom.
Making the look instead of converting it
If you are building a look from scratch for video, it is quicker to grade a frame of the footage itself. The Luttie editor plays your clip with the grade on and exports the result as a .cube. To check what a LUT does before using it, try the before and after slider.
Frequently asked questions
Can I convert a Lightroom preset (.xmp) to a .cube LUT?
Yes, but how depends on what the .xmp holds. A profile built from a LUT stores a 3D colour table, and this tool reads that table straight into a .cube. A develop preset stores slider settings instead, and only Lightroom can run those. For a preset, download the reference picture here, apply the preset to it in Lightroom, export it, and bring it back: the tool reads the colours and writes the .cube.
Why can't a slider preset be converted directly?
A preset is a list of settings such as exposure, tone curve and HSL, and the result depends on Adobe's own processing. Reproducing that outside Lightroom means guessing. Applying the preset to a picture that contains every colour, and reading what came out, records exactly what Lightroom did.
What gets lost when a preset becomes a LUT?
Anything that isn't a colour-for-colour change. A LUT maps each input colour to one output colour, so grain, sharpening, clarity, texture, dehaze, vignettes and masks can't be stored in it. Switch those off before exporting the reference picture, or they will be baked in as noise.
How do I use the .xmp profile in Lightroom?
In Lightroom Classic, open the Profile Browser in the Develop module, click the plus button and choose Import Profiles, then pick the .xmp. It appears in a group called Luttie with an Amount slider. Camera Raw in Photoshop has the same import option in its profile browser.
Is the conversion exact?
Between .cube and .3dl, and from a LUT-based profile to .cube, the colours are the same to within rounding. A .cube going into an .xmp is resampled to 32 points per side, the most a profile can hold, which is not visible on a normal look. The reference-picture route is exact for PNG and TIFF exports and very slightly soft for JPEG.
Is it free, and are my files uploaded?
It is free with no account, and the files never leave your computer: they are read and converted in the browser.
