Custom EmojisMAX 256 KB

File Size: Under 256 KB

Official Discord guidelines require custom animated emojis to be under 256 KB. Discord recommends uploading images sized at 128×128 pixels, which Discord automatically scales down for chat rendering.

Our preset applies a 250,000-byte target (leaving safety margin) and 128×128 fit.

Why Might a Compressed GIF Still Fail to Upload to Discord?

  • Server Permissions: You must have the "Manage Emojis and Stickers" permission on the Discord server to add custom emojis.
  • Emoji Slot Limits: Unboosted servers have a limit of 50 animated emoji slots. If all slots are full, new uploads will fail regardless of file size.
  • File Name Restrictions: Discord emoji names must be at least 2 characters long and only contain alphanumeric characters and underscores.
  • Transparency Issues: Emojis with corrupted color tables may render with black artifacts. Check transparent edges and animation transitions in the preview.
