🧷 Step-by-Step: Upload a GIF Emoji to Slack

  1. Convert Your GIF to a Compatible Size:

    • Slack supports GIF uploads as custom emoji, but it must be:

      • Square (e.g., 128x128 pixels).
      • Maximum 128KB.
      • Animated GIFs are supported (though Slack may trim or compress them).

    ✅ Tip: Use a tool like AnimGifMofji.com to resize and compress your GIF.

  2. Open Slack in a Browser:

    • Go to your Slack workspace at https://<your-workspace>.slack.com.
    • Click on your workspace name in the top left.
    • Select "Customize Slack" from the menu. This will open the emoji customization page in a browser.

    Alternatively, go directly to: https://slack.com/customize/emoji

  3. Upload Your Custom GIF Emoji:

    • Click the "Add Custom Emoji" button.
    • Name your emoji (e.g., party_dino). You’ll use :party_dino: to insert it.
    • Click "Upload Image" and select your resized GIF file.
    • Click "Save".

  4. Use the Emoji in Slack:

    • Type :<emoji_name>: to use it.
    • For the above example: :party_dino: 🎉

🔁 Replacing or Removing a Custom Emoji

  • On the same customization page, you can edit or delete your uploaded emojis.
  • Only workspace admins or those with permission can remove or rename emojis uploaded by others.
