What is the difference between Message and Emoji modes?

Message mode optimizes for 480x480 resolution and a ~2MB limit, while Emoji mode optimizes for 128x128 resolution and a strict 64KB limit with reduced color depth.

How does it handle Slack's 64KB emoji limit?

The skill uses aggressive optimization strategies including reducing the color palette (typically 32-48 colors), limiting frame counts, and utilizing specialized saving methods to ensure emojis meet strict Slack upload requirements.

Can I combine multiple animation effects?

Yes, the animation primitives are designed to be composable. You can apply multiple effects, such as combining a bounce motion with a shake effect, to create unique and complex animations.

Does it support text in GIFs?

Yes, it includes typography helpers specifically designed for small GIFs, featuring text-with-outline rendering to maintain readability on dark and light Slack backgrounds.

设计工具

Generates and optimizes animated GIFs and emojis tailored specifically for Slack's size constraints and formatting requirements.

关于

The Slack GIF Creator is a specialized toolkit designed to help developers and designers produce high-quality, lightweight animations for Slack. It features built-in validators to ensure GIFs meet strict file size limits—particularly the challenging 64KB emoji limit—and provides a library of composable animation primitives like shaking, bouncing, and spinning. This skill streamlines the creative process by handling technical optimizations like color quantization, frame rate management, and dimension validation automatically.
