Steps
Step-by-step instructions for creating and uploading Slack emojis.
FAQ
Slack recommends 128×128 px images under 128 KB. PNG works for static emojis, and animated GIFs are fully supported as long as they stay under the size limit.
Yes! Upload GIF files under 128 KB to Slack’s custom emoji page. MakeEmoji can export optimized GIFs or WebP files—use GIF when uploading to Slack.
Reduce the export size to 128px, shorten the animation, or simplify colors. Our exporter also offers WebP previews—convert to GIF after optimizing for the best balance of quality and file size.
Slack uses colon-wrapped names (e.g., :party-parrot:). Pick a short, descriptive name when you upload so your team can search for it quickly.
