Try ShrinkFile FreeOnline 3D LUT Previewer
Preview, inspect and convert .cube/.3dl/.lut/HALD files instantly.
Free Online 3D LUT Viewer & Tester
Instantly visualize standard Look Up Tables (LUTs) like .cube, .3dl, .lut (3D and 1D) and HALD CLUT .png on your own images and video clips. No need to launch heavy software like Adobe Premiere Pro, DaVinci Resolve, or Final Cut Pro just to check a color grade. This tool is perfect for video editors, colorists, and photographers who want a quick, lightweight workbench for their LUT libraries.
Real-time WebGL Rendering
We use your device's graphics card (GPU) to apply standard 3D LUT mathematics instantly. Whether it's a 16pt, 33pt, or 65pt LUT, the preview is instant and accurate.
100% Private & Secure
Unlike other online converters, this tool runs entirely in your browser. Your personal photos and proprietary LUT files are never uploaded to any server.
Intensity Control
Many LUTs are too strong by default. Use the built-in Intensity Slider (linear or smooth curve) to blend the LUT with the original image, just like the "Opacity" or "Gain" controls in professional video editing software.
Compare, Exposure & Contrast
Use the Compare Split to check original vs. graded side-by-side, plus quick Exposure and Contrast adjustments to dial in your preview.
Batch LUT Preview with Thumbnails
Load your whole LUT library at once — every LUT renders as a live thumbnail of your image, so you can compare dozens of looks at a glance. Export the whole comparison as a single contact sheet JPG, and your library is saved locally in the browser for next time. Built-in test charts (color checker, gradient ramps, color bars, skin tones) let you evaluate LUTs even without your own footage.
Video Preview & LUT Export
Drop in a short video clip to see your LUT on moving footage with play/pause and scrubbing. Dialed in the intensity? Export a new .cube with the strength baked in — this also converts .3dl, .lut, and 1D LUTs to .cube format.
Built-in Scopes
Judge grades like a colorist: a live histogram, RGB parade waveform and vectorscope (with 75% targets and skin-tone line) update in real time — even during video playback — so you can spot clipping, casts and skin-tone shifts instantly.
Log Footage LUT Support
Testing a camera LUT designed for S-Log3, V-Log, or ARRI LogC? Pick the input color space and the previewer converts your image into log before applying the LUT — so conversion LUTs look right instead of washed out.
