Slack Emojis for Every Workspace

Workspace Culture & Branding

Build your team's unique culture with custom Slack emojis. Create reactions that represent inside jokes, company values, or memorable moments. Design emojis featuring your company logo, mascot, or team traditions. Help remote teams feel connected through shared visual language.

Team Communication & Reactions

Enhance async communication with expressive custom reactions. Create emojis for common responses like "reviewing", "deployed", "approved", or "need coffee". Replace text-heavy replies with quick emoji reactions that keep conversations flowing. Perfect for standups, feedback, and celebrations.

Department & Channel Identity

Give each department or channel its own emoji identity. Design custom emojis for engineering, design, sales, marketing, and support teams. Create channel-specific reactions for announcements, wins, or blockers. Help new team members understand workspace dynamics through visual cues.

Slack Emoji Maker FAQs

What size do Slack emojis need to be?+

Slack asks for square images under 128KB, and 128×128 is the size that renders cleanly. Animated GIFs are capped at 50 frames. EmojiCreator.ai exports at 128×128 by default.

How do I add a custom emoji to Slack?+

In Slack, click your workspace name → Settings & Administration → Customize your Workspace → Add Custom Emoji. Upload your PNG or GIF file and give it a name. You need admin or the "Add Custom Emoji" permission.

What format do Slack emojis need to be?+

Slack accepts PNG, JPEG, and GIF formats. PNG with a transparent background is recommended for the best display. GIF files support animation — Slack will display the animation when the emoji is used in messages.

Can free Slack workspaces add custom emojis?+

Yes. Every Slack workspace, free plans included, can add unlimited custom emoji. The constraint is per file rather than per workspace: each one has to come in under 128KB.

How many custom emojis can a Slack workspace have?+

There is no cap on how many custom emoji a workspace can hold, on any plan. The limit is per file: under 128KB each.

Can I use animated GIFs as Slack emojis?+

Yes. Upload a GIF under 128KB and no longer than 50 frames, give it a name, and Slack animates it wherever the emoji appears. Shorter loops read better at emoji size.

Upload limits, platform by platform

The ceilings differ enough that a file which works on Discord can bounce off Teams. These are the numbers each platform publishes.

Platform	Max size	Dimensions	Formats
Slack	128 KB	square, 128×128 recommended	PNG, JPG, GIF (up to 50 frames)

Slack: Transparent backgrounds render best against both themes.
