How does the tool ensure text is readable in small emojis?

The skill includes a typography helper that automatically applies high-contrast outlines to text, ensuring legibility even at the 128x128 pixel dimensions required for emojis.

Do I need to manually optimize the GIF file size?

No, the built-in GIFBuilder automatically handles color quantization, duplicate frame removal, and provides real-time size warnings based on Slack's specific requirements.

Does this skill handle Slack's strict 64KB emoji limit?

Yes, it includes specialized optimization strategies such as reducing frame counts to 10-15 and limiting color palettes to 32-48 colors to ensure compliance with the 64KB limit.

Can I layer multiple animation effects?

Absolutely. The toolkit is designed with composability in mind, allowing you to combine primitives like 'bounce' and 'shake' to create complex, customized animations.

What animation types are included?

The toolkit features a wide range of primitives including Shake, Bounce, Spin, Pulse, Fade, Zoom, Explode, Wiggle, Slide, Flip, Morph, and Kaleidoscope effects.

Generates and optimizes animated GIFs and custom emoji animations tailored specifically for Slack's technical file size and dimension constraints.

关于

Slack GIF Creator is a comprehensive toolkit designed to help developers and designers build perfectly optimized animated content for the Slack ecosystem. It provides a suite of composable animation primitives—including shakes, bounces, morphs, and kaleidoscopes—alongside strict validation tools to ensure assets meet Slack's message size (2MB) and emoji size (64KB) limits. By automating complex tasks like color quantization, frame management, and typography outlining, this skill allows users to transform simple descriptions into high-quality, platform-ready visual assets while maintaining complete creative control.
