A LUT (look-up table) is a colour grade stored as a table rather than as a list of settings. Instead of recalculating contrast, saturation and colour balance for every pixel, the table already says which output colour each input colour becomes, so applying it is a lookup. That is why one file grades identically in DaVinci Resolve, Premiere Pro, Final Cut Pro, Photoshop and on this page.

Why does my LUT look wrong on this photo?

Almost always because it was built for a different kind of input. LUTs come in two sorts: technical ones that convert flat camera Log footage (S-Log3, V-Log, Apple Log) into normal colour, and creative ones that lay a look over an ordinary photo. A Log conversion applied to a normal photograph blows out the contrast and saturation; a creative look applied to Log footage comes out washed out. Nothing inside a .cube file says which it expects, so the filename or the seller's description is the only clue. The other cause is simply strength - a look built against one reference photo is usually too strong on yours, which is what the slider is for.

Is my photo or my LUT uploaded to a server?

No. Both are read straight from your device, and every lookup happens on a canvas inside this browser tab. Nothing is sent to YouArt or to any third party, which also means there is no stored copy for anyone to access later. If you turn off your network after the page loads, the tool still works.

Do 1D LUTs work, or only 3D?

Both. A 1D LUT is three separate curves, one per channel, so it can change brightness, contrast and gamma but not saturation or a hue shift, because those depend on all three channels at once. A 3D LUT is a cube of colours and can do all of it. This page reads both, and converts a 1D file onto a 65-point cube so it grades the same way either path.

Can this add film grain, halation or a vignette?

No, and the reason is worth knowing because it applies to every LUT everywhere. A look-up table answers one question per pixel: given this colour, what colour should it become. It never learns where the pixel is, so it cannot add anything that depends on position - grain, halation, bloom, vignetting, dust, scratches or light leaks. A film emulation LUT gives you the colour half of a film look and nothing else. If you want grain as well, add it afterwards in an editor that does spatial effects.

Can I apply a LUT at less than full strength?

Yes, at any percentage. The slider mixes the graded result back toward your original picture and the preview follows as you drag. A .cube you download afterwards carries that strength baked into the table, so it lands the same way in your editor as it looked here.

How is this different from Photoshop's Color Lookup layer or a LUT plugin for Lightroom?

The arithmetic is the same - a 3D LUT applied with trilinear interpolation - so a .cube grades the same way here as it does there. The difference is what you have to have open. This runs in a browser tab with nothing installed, nothing uploaded and no subscription, and it draws every look on your own photograph before you choose one, which a plugin's list of names cannot. Photoshop and Lightroom win where you need the rest of an editor: masks, local adjustments, curves, raw files, or a whole folder at once. This page grades one photo and hands it back. It also exports the look as a .cube, so anything you set here can be taken into Resolve, Premiere, Final Cut or Photoshop - including onto footage, which this page does not touch.

Can I download the looks as .cube files?

Yes. Any look active on this page can be saved as a .cube and used in DaVinci Resolve, Premiere Pro, Final Cut Pro, Photoshop or anything else that reads LUTs. The ten built-in looks are ours - written as arithmetic rather than borrowed from a pack - so they are free to use and free to keep.

Can a LUT make a photo black and white?

Yes. Mono Contrast converts the picture to greyscale using the standard Rec.709 luma weights and then adds contrast, and Sepia does the same conversion with a warm tint over it. Because it is a LUT, the strength slider works on it too, so you can stop halfway and keep a trace of the original colour. What you do not get is a black-and-white workshop: there is no channel mixer and no simulated red or yellow lens filter, so you cannot darken a blue sky independently of the rest of the frame. It is one conversion, done well, with a dial.

Where do I get LUTs to use here?

The ten built into this page are a start, and any .cube file works: packs you have bought, free packs you have downloaded, or a LUT you exported from your own grade in Resolve or Lightroom. This page does not host anyone else's pack.

How do I make my own LUT?

Download the base grid from the panel above. It is a 512 x 512 PNG holding all 262,144 colours of a 64-point cube, one per pixel, so grading it records what your grade does to every colour there is. Open it in any editor, grade it however you like, and save it as a PNG - the graded grid IS a LUT, and RawTherapee, G'MIC and ImageMagick read that file directly. Two rules matter. Save as PNG and never JPG, because every pixel is a table entry and lossy compression corrupts the table itself. And use colour adjustments only: curves, white balance, saturation, a look you already own. Grain, blur, vignetting and sharpening destroy the grid rather than being recorded in it, because neighbouring pixels here are unrelated colours rather than neighbouring parts of a picture. This page itself reads .cube files, so take the graded grid to an app that accepts Hald PNGs, or convert it to .cube and load that here.

Free photo tool

Apply a LUT to a Photo

Drop in a picture and see every look on it at once - ten film and cinematic grades, drawn on your own photo rather than on a stock thumbnail. Bring your own .cube file if you have one, dial the strength to taste, then download the image or the look. It all happens in this tab, and your photo is never uploaded.

Examples

Three Looks on One Photograph

Golden Hour
Golden Hour at full strength. A warm cast and a lift in saturation, on light that was already coming through a window.
Moody Blue
Moody Blue. The golden-hour warmth is pulled out of the whole frame, cobbles and sky together, leaving the pastel facades in cold light.
Cross Process
Cross Process. The channels are pulled against each other the way crossing film chemistry does: gold in the sky and the peaks, green through the water.

How it works

Grade a Photo in Three Steps

Step 1
Open your photo
Drag a JPG, PNG or WebP onto the page, or pick one from your device. No photo to hand? Take one of ours. Either way it loads straight into the editor without being sent anywhere.
Step 2
Pick a look, or drop a .cube
Every look is drawn on your own picture, so you choose by looking rather than by name. Load any 1D or 3D .cube file if you have one, and set the strength anywhere from a hint to the full grade.
Step 3
Download the result
Save the graded photo as PNG, JPG or WebP - or save the look itself as a .cube, with the strength baked in, for Resolve, Premiere, Final Cut or Photoshop.

What you can do

Four Ways to Colour Grade a Photo

Ten looks, on your photo

Film-look, cinematic, faded, warm tone and black-and-white grades, each one rendered on the picture you loaded rather than on someone else's sample, so you can see what it does to your skin tones and your sky before you commit.

Any .cube you own

A .cube previewer as much as a grader: drop in a LUT from a pack you bought, downloaded or exported yourself and it is drawn on your own photo, not on a stock thumbnail. Both 1D and 3D .cube files are read, up to 65 points per axis, and a 1D file is converted so it grades the same way.

Strength, not all or nothing

Most LUTs were built against a different photo than yours and land too strong. The slider mixes the grade back toward your original, live, at any percentage.

Export the look as a .cube

Take the look with you: download it as a .cube file with the strength you chose baked in, and it grades the same way in any editor that reads LUTs.

Where your photo goes

The Grade Happens in Your Browser

Most online photo tools upload your file, process it on a server and send it back. This one does not have a server to send it to.

Nothing is uploaded

Your picture and your LUT are read from your device and used on a canvas in this tab. Neither is ever sent to us or to anyone else, and there is no copy of either to delete afterwards.

No account, no credits

There is nothing to sign up for and nothing to spend. Open the page, grade the photo, close the tab.

No watermark, no queue

Because the work happens on your own machine there is no job to wait behind and nothing stamped on the result. Grade as many photos as you like.

What people use this for

Where a LUT Earns Its Keep

One look across a set

A LUT is a fixed function of colour, so it does the same thing to every picture. That is what makes a shoot, a product set or a feed read as one body of work rather than a folder.

Match stills to your footage

Apply the same .cube you graded a clip with to the photographs from the same shoot, so the thumbnails and the video agree.

A recognisable feed

Pick one look and keep it. Consistent colour is most of what makes a set of posts look like a brand rather than a collection of pictures.

Try a LUT before you use it

Drop a .cube from a pack onto a real photo and see what it does to skin and sky, at full size, before it goes anywhere near a timeline.
