How to Create Custom Slack Emojis

This practical guide shows how to turn any idea or image into an emoji‑style PNG with a transparent background, then add it to Slack as a custom emoji. You can either ask an AI to generate an emoji‑style graphic from a prompt or upload an image and ask it to edit it into emoji style with background removed.

File guidelines

Slack recommends square images under 128 KB with transparent backgrounds. PNG, JPG, and GIF are supported (GIFs up to 50 frames).

What you will need

Slack on desktop or web
An image generator or editor that can export transparent PNG
Square output (128 × 128 px recommended), ideally under 128 KB
A short, memorable emoji name (for example, :team‑logo:)

Step 1: Create or transform your image into emoji style

Option A: Prompt an AI to create an emoji‑style asset from scratch. Option B: Upload an existing image and request an edit that converts it into emoji style, removes the background, centers the subject, and outputs a transparent PNG.

Example: prompt to emoji style and resulting transparent PNG

Ask for a centered, emoji‑style illustration with no background
Prefer a bold outline and simple shading for legibility at small sizes
Export transparent PNG, square, ideally 128 × 128 px

Pro tip

Keep backgrounds transparent and subjects centered. Preview at small size to ensure edges are clean.

Step 2: Download the transparent PNG

Download the generated or edited image to your device. Confirm it is square, transparent, and under 128 KB. If needed, resize to 128 × 128 px and compress lightly to meet Slack guidance.

Step 3: Upload your custom emoji to Slack

On desktop: open the emoji picker, choose Add Emoji, upload the PNG, give it a short name, then Save. Your emoji will appear in the Custom section of the picker.

Slack Add Emoji button in the emoji picker

Click the smiley icon in the message field to open the emoji menu
Select Add Emoji
Click Upload Image and select your PNG
Enter a short name (for example, :team‑logo:)
Click Save and test it in a message

Your custom emoji visible and ready to use in Slack

Naming tip

Name your emoji clearly so teammates can find it by typing a colon and the name in the message box.

Troubleshooting and tips

If edges look jagged, add a subtle outline and export again
If the background appears white, ensure PNG transparency is enabled
If the image is larger than 128 KB, resize to 128 × 128 px and compress
Keep details simple so the emoji reads well at small sizes

Square images under 128 KB and with transparent backgrounds work best.
