How It Works

Professional color correction in three steps.

1

Upload Your Video

Drag and drop or click to browse. Any format your browser can decode is supported — MP4, MOV, WebM, AVI, MKV and more.

2

Correct & Grade

Use Tone, Color, Curves, RGB, FX and LUT tabs to dial in your grade. Watch the live histogram and canvas preview update in real time as you adjust.

3

Export & Download

Click Export to render the full video with every correction baked into every frame. Download as WebM, MP4, or MKV instantly.

Professional Tools, Zero Cost

Everything a colorist needs — running entirely in your browser.

Full Tone Panel

Exposure, contrast, highlights, shadows, midtones, whites and blacks — the same 7-parameter tone panel found in professional grading software.

Live RGB Histogram

A real-time RGB histogram updates with every frame and every slider move, showing you exactly where your tones are distributed across shadows, midtones and highlights.

Interactive Tone Curves

Click to add control points, drag to reshape the RGB or individual R, G, B curves. The curve is applied as a pixel-level lookup table over the Canvas pixel data.

RGB Channel Control

Independently adjust the Red, Green and Blue channels. One-click cast removal buttons instantly neutralise warm, cool, green or magenta colour casts.

12 Cinematic LUT Presets

Cinematic, Golden Hour, Teal & Orange, B&W Film, Sepia, Cool Blue, Sunset, Matte, Moody, Vivid, Vintage — applied on top of your manual corrections.

100% Private

Every correction runs inside your browser using Canvas 2D pixel manipulation and CSS filters. Your video never leaves your device — no uploads, no accounts.

Frequently Asked Questions

What is the difference between color correction and color grading?
Color correction fixes technical problems — exposure, white balance, shadow and highlight clipping — to make footage look natural and neutral. Color grading is a creative step that gives footage a specific mood or cinematic look using LUTs, hue shifts or stylistic choices. This tool does both: use the Tone and Color tabs to correct, then the LUT tab to grade.
How do I fix overexposed or underexposed video?
For overexposed footage, reduce the Exposure slider and pull down the Highlights and Whites sliders in the Tone tab. For underexposed footage, raise Exposure, then bring up Shadows and lift the Blacks slider slightly. Watch the live histogram to ensure you are not clipping at either end.
How does the tone curve work?
The tone curve maps input pixel values (x axis) to output values (y axis). A straight diagonal line means no change. Click to add control points, then drag them to reshape the curve. Pulling the upper portion up brightens highlights; pulling the lower portion down crushes shadows. You can edit the RGB master curve or individual Red, Green and Blue channels separately.
What is vibrance and how is it different from saturation?
Saturation boosts all colours equally — increasing it can push already-vivid colours into clipping. Vibrance is a smarter boost that targets muted, undersaturated colours more than already-vivid ones, giving a more natural and balanced result. For skin tones, vibrance is almost always preferable to saturation.
Is my video uploaded to a server?
No. All color correction is done in your browser using the HTML5 Canvas 2D getImageData and putImageData APIs for pixel-level adjustments, and CSS filter strings for accelerated effects. Nothing is uploaded — your video stays on your device.
Can I export a still frame with corrections applied?
Yes. Scrub to any moment using the timeline, adjust your corrections, then click Snapshot in the controls panel. The current canvas frame with all corrections applied is saved as a PNG file.

How Pixel-Level Color Correction Works in the Browser

Each video frame is drawn onto an HTML5 Canvas. The 2D context's getImageData() method extracts raw RGBA pixel data as a flat array. Tone adjustments like exposure, shadows, highlights, and the custom curve are implemented as lookup tables — a 256-entry array mapping each input value (0–255) to an output value. RGB channel adjustments apply independent multipliers per channel. This approach is fast enough for real-time preview at reduced canvas resolution and produces accurate results for full exports.

LUT Presets Explained

LUT stands for Look-Up Table — a pre-built set of colour mappings that transform flat or neutral footage into a specific cinematic style. The 12 built-in LUT presets are simulated using combinations of saturation, hue shift, contrast, RGB channel mixing, and overlay compositing on the Canvas. They are applied after all manual adjustments, giving you a foundation grade that you can then fine-tune further.
