Slack recommends small square custom emoji files, ideally under 128KB, with transparent backgrounds for the cleanest result. Use Custom mode to create a square emoji export, then upload it through your Slack workspace emoji settings.

How to Resize Slack Custom Emojis
Prepare compact square emoji files for Slack workspace uploads.
Start with a Simple Image
Slack custom emoji display inline and small, so choose a bold face, symbol, logo mark, or reaction.
Set a Square Custom Size
Use Custom mode to create a square output suitable for Slack-style emoji use.
Preserve Transparent Edges
Use PNG when the emoji should not have a visible square background.
Keep the File Light
Simpler images compress better and are less likely to hit workspace upload limits.
Upload to Slack
Add the downloaded file through your workspace's custom emoji settings if you have permission.
💡 A Slack emoji should read instantly at inline size. If it depends on small text, simplify the artwork before uploading.
Slack Emoji Tips
Use Bold Shapes
Slack emoji display inline, so faces, icons, and simple marks work better than detailed screenshots.
Keep Files Small
Simpler PNGs are easier to upload and render quickly in workspace conversations.
Use Transparency for Cutouts
Transparent backgrounds make custom emoji feel native beside text.
Avoid Tiny Words
Most text becomes unreadable at Slack emoji size unless it is a very short, bold mark.
