LUT previewer: try many .cube LUTs on your own image
Drop in one frame from your footage and as many .cube LUTs as you like, and see every look side by side on your own shot.
Your image, video and LUT files are read on this device. Nothing is uploaded.
Your frame
PNG, JPG or WebP, or a video to pick a frame from. Or drop it here.
Saves the frame you picked at full resolution, without a LUT (frames over about 24 MP are scaled down).
Your LUTs
Choose several files, or drop files or a folder here.
Honest limits: the preview applies each LUT to the 8-bit sRGB pixels your browser decodes, with trilinear interpolation. It is close to what an editor shows for display-referred (Rec.709) footage, not a color-managed reference. Log-to-Rec.709 LUTs expect log footage and will look wrong on a normal photo. RAW and HEIC files are not supported. 3D and 1D .cube files are supported.
Looks
Choose a frame and add LUTs to see one tile per LUT. Select a tile to compare before and after.
Before and after
How to preview LUTs on your footage
- Click Choose image or video. Pick a still image such as a PNG or JPG, or a video your browser can play. For a video, move the slider to the frame you want to test.
- Click Add .cube LUTs and select your files. You can select many at once, and in browsers that support it you can pick a whole folder.
- Each LUT appears as a tile with its name, applied to your frame. Scroll the grid and note the looks that suit the shot.
- Click a tile to open it large with the Before/after slider. Drag the slider, or focus it and use the arrow keys, to compare the graded and original image.
- Click Download graded image (PNG) to save that look at full resolution, or Download grid (PNG) to save a contact sheet of every tile with its LUT name.
What this tool fixes
A new LUT pack usually means importing dozens of files into your editor and clicking through them one at a time. Adobe Community users have asked for something better for years. A thread started in 2020 asks how to "display a sample frame of every LUT in a directory/folder", and a 2023 feature request asks for "a grid preview of multiple LUTS along with the ability to group luts in folders". This page gives you that grid in a browser tab, with nothing to install.
DaVinci Resolve's LUT Browser can already preview a LUT on the current clip while you hover over it. The grid helps when you want to see a whole pack side by side, or check LUTs away from your editing machine.
Which LUTs this preview suits
The preview applies each LUT to the 8-bit sRGB pixels your browser decodes from the image. That suits creative LUTs made for normal, display-ready video (Rec.709), such as film looks, black and white, or warm and cool grades. It is not meant for log footage. Conversion LUTs from log to Rec.709 expect a flat log image as input, and on an ordinary photo they push contrast and saturation much too far. Judge those inside your editor, on the footage they were made for.
Using the LUT you picked
- Premiere Pro: Adobe's help page on installing custom LUTs, as indexed in October 2026, says files saved in the Creative subfolder of Adobe's shared LUTs folder appear in the Lumetri Color panel under Creative > Look, and that Basic Correction > Input LUT has a Browse option for a one-off file. The same page gives the folder location for Windows and macOS. Menu names can differ between Premiere versions, so check that page for yours.
- DaVinci Resolve: copy the file into Resolve's LUT folder and click Update Lists. The Lookup Tables section of Project Settings has an Open LUT Folder button for this. Then, on the Color page, drag the LUT from the LUT Browser onto a node, or right-click a node and choose it from the 3D LUT submenu.
- CapCut (desktop): CapCut's own guide says to open the Adjustment tab, choose LUT and click Import to load a .cube file.
To pull the main colors out of a frame as hex codes, for a mood board or to compare looks, use color palette from video.
Limits
- The preview approximates what an editor shows. It works on 8-bit sRGB pixels, while editors grade at higher bit depth with their own color management, so expect small differences, especially in smooth gradients like skies.
- LUTs are applied with trilinear interpolation, which is also DaVinci Resolve's default. If your Resolve project uses tetrahedral interpolation, the result can differ slightly.
- It reads .cube files with a 3D LUT of 2 to 65 points per side or a 1D LUT of 2 to 65,536 entries. Shaper LUTs, which combine a 1D and a 3D LUT in one .cube file, are refused with a message asking for a 3D-only file. DaVinci Resolve can use shaper LUTs, so a file that works there may still be refused here. Other formats such as .3dl aren't supported, and any file that can't be read gets a message naming it.
- RAW photos and HEIC images aren't supported. Convert them to PNG or JPG first.
- Video frames come from whatever your browser can decode, so some camera files won't open. Export a still from your editor instead.
- The grid uses a smaller copy of your image, up to 640 px on the long edge, so it stays fast. The graded download uses full resolution. Images above about 24 megapixels are scaled down for export, and the tool warns you first.
Your files stay on your device
Your image and your LUT files are read by the browser and processed on your computer. Nothing is uploaded. That matters when the LUTs are paid files you aren't allowed to share, or the frame comes from an unreleased project.
Questions
Can I preview a whole folder of LUTs at once?
Yes. Click Add .cube LUTs and select every file in the folder, or pick the folder itself if your browser offers that. Each LUT becomes a named tile showing your frame with that look applied.
Why does a LUT look wrong on my image?
Usually the LUT was made for a different kind of input. Conversion LUTs for camera log footage expect a flat, low-contrast image, so on a normal photo or phone clip they look harsh and oversaturated. Check the pack's notes for what each LUT was built for. Creative LUTs for Rec.709 footage are the ones this preview shows accurately.
Will the look match Premiere Pro or DaVinci Resolve exactly?
Close, but not exactly. This preview works on 8-bit sRGB pixels with trilinear interpolation. Your editor may use higher bit depth, color management and a different interpolation setting, which shows up as small differences in gradients and saturated colors. Use the grid to choose, then make the final call in your editor.
Are my LUT files uploaded anywhere?
No. The LUTs and the image are read and processed by your browser on your device, and the page sends nothing while you use it.
Is there a free LUT previewer for Windows?
This one runs in a web browser, so there is nothing to install on Windows or on a Mac. Open the page, choose your frame and add your .cube files.
