Quick answer
Does Twitch auto-resize emotes?
Yes — Twitch can take one square image (for animated emotes, a GIF from 112 to 4096 px under 1 MB) and make the 112, 56 and 28 px sizes itself, though uploading your own three sizes gives you control over the 28 px one. Try the free Twitch emote resizer →
When to let Twitch resize
Bold, simple emotes with thick outlines survive automatic resizing well. Use auto-resize for those and save time.
When to upload three sizes
Emotes with text, thin lines or small details often turn muddy at 28 px when scaled automatically. Resize in halves with good smoothing, check the 28 px file at actual size, and upload all three. Our exports include the 512 px auto file and the three manual sizes so you can try both.
