Does it support text in animations?

Yes, it includes a typography utility specifically designed for small GIFs that adds outlines to text, ensuring readability even at 128x128 emoji dimensions.

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

The skill applies aggressive color quantization (32-48 colors), reduces frame counts to 10-15 total, and uses duplicate frame removal to ensure animations stay under the strict limit.

What are the optimal settings for Slack message GIFs?

For standard messages, the skill defaults to 480x480 dimensions, 15-20 FPS, and a 256-color limit to balance visual quality with the 2MB file size cap.

Can I combine different animation effects?

Yes, the toolkit is built with composable primitives, allowing you to layer multiple effects—such as combining a bounce motion with a shake impact—on any object.

Design Tools

Generates and optimizes animated GIFs and custom emojis specifically tailored for Slack's strict file size and dimension constraints.

The Slack GIF Creator skill is a comprehensive toolkit designed to help users build expressive, high-performance animations directly within Slack's ecosystem. It provides specialized validators to ensure GIFs meet the challenging 64KB limit for custom emojis and the 2MB limit for standard messages, alongside a library of composable motion primitives like bounces, shakes, and morphs. By automating technical optimization—such as color quantization, frame rate management, and dimension scaling—it allows developers to focus on creative vision while guaranteeing the output is ready for immediate upload to Slack.
