Turn ReShade PNG LUTs into Photoshop .cube files, right in the browser.
ReShade color grades live in PNG LUTs, but Photoshop's Color Lookup layer wants .cube files — and there's no built-in way across. Most converters are a CLI you have to install first; this is the no-install version: open a page, drop the PNG, download the .cube.
It all runs in the browser with the Canvas API, so a LUT never leaves your machine and the tool works offline. It auto-detects the layout — strip, MultiLUT atlas, or HALD — and previews the look on a sample or your own screenshot before you export.
- Auto-detects the input layout — ReShade strip, MultiLUT atlas, or HALD CLUT
- Runs entirely client-side via the Canvas API — nothing is uploaded, works offline
- Live before/after preview with a strength slider that never touches the exported file
- Maps each LUT pixel straight to its 3D cube coordinate, normalizing 8-bit values to 0–1 floats — a direct transcription, no resampling or interpolation
- Framework-free core, cross-checked byte-for-byte across formats in tests
