A photograph color-graded in Kalar

GPU-accelerated

A WebGL2 engine renders every adjustment in real time.

Private by design

Images are decoded and processed locally — nothing is uploaded.

Install once and keep editing without a connection.

Inside the editor

A pro grading desk, in a browser tab.

Live scopes, tone curves and color controls all update in real time as you grade — the desktop experience, with nothing to install.

Film grading features

Everything needed to build, match, and export cinematic looks

True RAW decoding

Open camera RAW, HEIC and TIFF with a high-bit-depth pipeline that protects highlight and shadow detail.

Cinematic color

Curves, color wheels, HSL and live scopes give you precise, filmic control over tone and mood.

Presets & LUTs

Build, import and share looks. Apply 3D LUTs and one-click presets across an entire shoot.

Reference matching

Match the palette of any reference image and let Kalar rebuild the grade for you.

Studio-grade export

Export high-resolution images with your color science baked in, ready to deliver.

Installable & offline

A progressive web app that installs to your desktop and keeps working offline.

The grading stack

Sixteen image adjustment panels for color grading

The Kalar editor stacks sixteen GPU-accelerated panels for photo color adjustment and film grading — from AI reference matching and tone curves to scattering, refraction, halation, bloom, diffusion, and film grain. Panels marked “Included in LUT Exports” bake into your 3D LUT; FX panels are real-time, render-only optical effects.

Presets

Start from curated film looks and preset packs, then refine every panel to taste.

Adjustment panel

Color Match^AI

Match the color, brightness and contrast of a reference image to your current image. Ideal for replicating film looks or kickstarting a grade.

Included in LUT Exports

Balance

Adjust global exposure, saturation, temperature and tint with the 2-axis controls.

Included in LUT Exports

Exposure Curve

Shape brightness across shadows, midtones and highlights with precise control over luminance ranges.

Included in LUT Exports

Contrast Curve

Adjust contrast distribution across tonal zones with film-density modeling and full control over curve shape.

Included in LUT Exports

Scattering

Add physically accurate shadow and highlight tinting based on natural light behavior using the two color wheels.

Included in LUT Exports

Refraction

Filmic HSL. Change hue and saturation in shadows and highlights independently for all color vectors.

Included in LUT Exports

Density Curve

Control color richness and saturation hue-by-hue, based on analog film density behavior.

Included in LUT Exports

Chroma Curve

Adjust saturation based on how colorful pixels already are. Boost muted tones or protect vibrant highlights.

Included in LUT Exports

Radiance Curve

Adjust brightness per hue for subtle tonal balancing and natural color contrast without masking.

Included in LUT Exports

Saturation Curve

Control saturation across brightness ranges. Boost shadows or reduce highlights to avoid color clipping.

Included in LUT Exports

Shadow Highlight

Adjust brightness and introduce subtle hue shifts separately in the shadows and highlights of your image.

Included in LUT Exports

Spotlight^FX

Dynamic re-illumination with localized exposure and pop. Drag the point on the image to position the light; double-click it to recenter.

Render-Only (Not Included in LUTs)

Halation^FX

Simulate the iconic red-orange glow around highlights seen in analog film photography.

Render-Only (Not Included in LUTs)

Diffusion^FX

Real-time optical diffusion that softens highlights while maintaining subject focus. Drag the point on the image to position the protected area; double-click it to recenter.

Render-Only (Not Included in LUTs)

Texture^FX

Re-texture every pixel with volumetric film grain and localized micro-contrast, from fine 35mm to gritty ISO 800.

Render-Only (Not Included in LUTs)

Film emulation presets

Start from cinematic film looks, then make them yours

Use print film, night street, editorial, vintage negative, and modern cinema looks as flexible starting points. Refine density, curves, saturation, halation, bloom, grain, and export the final grade as a reusable look.

FAQ

Browser-based film grading answers

Short answers for photographers, filmmakers, and creators comparing web grading, film emulation, RAW editing, and LUT export workflows.

Is Kalar an online image editor?

Yes. Kalar is a browser-based image editor focused on color. It opens RAW photos and video frames and gives you sixteen adjustment panels for exposure, contrast, curves, color balance, and film grading — with no installation and no upload.

Is Kalar a browser-based alternative to Lightroom for color grading?

Yes. Kalar runs entirely in your browser and is focused on cinematic color grading — exposure, curves, film looks, halation, bloom, grain, AI reference matching, and 3D LUT export. You can build Lightroom-style looks without installing desktop software, managing a catalog, or uploading your photos.

Is Kalar faster and simpler than desktop photo editors?

For color work, usually yes. Kalar opens in a browser tab with no install, sync, or catalog setup, and keeps the toolset focused on color and film grading. That makes building a cinematic look and exporting a 3D LUT faster and simpler than learning a full desktop suite.

What image adjustments can I make in Kalar?

Kalar covers exposure and contrast curves, color balance, saturation, density, chroma, and radiance curves, shadow and highlight tinting, and AI color matching, plus film effects like scattering, refraction, halation, bloom, diffusion, and grain.

What is browser-based film color grading?

Browser-based film color grading is the process of shaping color, contrast, density, highlight rolloff, grain, halation, and cinematic looks directly in a web app without installing a full desktop grading suite.

Can I grade RAW photos in Kalar?

Yes. Kalar is designed for RAW photo grading workflows, giving photographers a browser-based space for exposure, contrast, curves, color matching, film texture, and reusable look creation.

Can I create and export a 3D LUT online?

Yes. Kalar lets you build a cinematic look in the browser and export it as a 3D LUT for use in compatible video editors, photo editors, and color-managed creative workflows.

Who is Kalar for?

Kalar is for photographers, filmmakers, creators, and color-focused teams who want a fast web workflow for film looks, reference matching, scopes, presets, and LUT export.
