Overview

Reduce the color palette of your GIF files to optimize file size while maintaining visual integrity and animation playback.

When to use

Compressing large GIF files for faster web loading speeds.
Preparing animated assets for platforms with strict file size limits.
Standardizing color palettes across multiple frames for consistent visual output.

How it works

1Upload your GIF file to the tool.
2Select a color reduction method like Quantization or Median Cut to define how colors are sampled.
3Adjust the target color count and dithering settings to balance file size against image quality.
4Process the file to generate an optimized version that preserves your original animation frames.

Use cases

Optimizing animated banners for email marketing campaigns.
Reducing the footprint of UI icons and small animations on websites.
Batch-processing social media assets to meet upload size requirements.

Examples

1. Optimizing Web Banner for Performance

Web Developer

Background

A marketing team provided a 5MB animated GIF banner that is slowing down the landing page load time.

Problem

The file size is too large for optimal web performance.

How to use

Upload the banner, set the target color count to 64, and use the 'Wu' quantization method.

targetColors: 64, colorReductionMethod: 'wu', ditheringMethod: 'floyd-steinberg'

Outcome

The file size is reduced by over 60% while maintaining clear text and smooth animation.

2. Preparing Assets for Mobile App

UI/UX Designer

Background

An animated loading spinner needs to be included in a mobile app, but the current file is too heavy.

Problem

Need to reduce file size without losing the transparency of the spinner background.

How to use

Upload the spinner GIF, enable 'Preserve Transparency', and use the 'Median Cut' algorithm.

preserveTransparency: true, colorReductionMethod: 'median-cut', targetColors: 32

FAQ

Will reducing colors affect the animation?

No, the tool is designed to preserve animation frames while optimizing the color palette used within those frames.

What is the best method for high-quality results?

Quantization or Wu Quantization generally provide the best balance between color accuracy and file size reduction.

Can I keep the background transparent?

Yes, enable the 'Preserve Transparency' option to ensure transparent areas remain intact during the color reduction process.

How many colors should I target?

Standard GIFs use up to 256 colors. Reducing this to 64 or 128 can significantly decrease file size with minimal visual impact.

What does dithering do?

Dithering simulates colors that are not in the reduced palette by creating patterns of pixels, which helps prevent banding in gradients.
