PALETTE FORGE GUIDE

Image and video color redesign

PaletteForge is a browser tool that transforms images and videos with limited palettes and pixel styling. Lock exact colors when they matter, then let the remaining palette follow the source mood or favor broader color variety.

HOW TO USE

Core features and workflow

Edit and batch-export images in detail, or convert video with one consistent palette or a scene-responsive palette generated for each frame. The example images provided on the site were generated with AI.

01

Media import

Load multiple PNG, JPEG, or WebP images, or paste one with Ctrl+V. The video converter accepts one MP4 or WebM file at a time.

Alpha in transparent PNG and WebM is preserved where the browser and output support it.
02

Color adjustments and pixel style

Tune brightness, contrast, saturation, and hue. Enable pixelation when needed, then choose block size and alpha behavior.

Adjustments never accumulate; every result is recalculated from the source.
03

Palette size and character

Set the final color count and move the automatic palette between dominant colors, source balance, and broader color diversity. Ready-made presets are also available.

Transparent pixels are excluded from representative-color analysis.
04

Fixed colors and weights

Use HEX, RGB, or the image eyedropper to lock exact colors, then control their matching range with per-slot weights.

Automatic palette-per-frame video mode generates colors for each scene instead of using fixed slots.
05

Video palette strategy

Common mode samples the full timeline and applies one palette throughout. Per-frame mode updates the palette with scene-change detection and temporal stabilization.

Common mode favors consistency; per-frame mode follows the colors of each scene.
06

Review and export

Save images as PNG, JPEG, or WebP and videos as MP4 or WebM to match the input container. Compatible source audio is preserved without re-encoding.

Long or high-resolution videos may take substantial time depending on the device.
