Emotes are rejected for one reason more than any other: the wrong pixel dimensions. Platforms require exact sizes and will not scale for you, so an emote that is 100 pixels instead of 112 simply fails to upload.
What the Emote & Sticker Resizer does
Resizes a single image into the exact set of sizes a platform requires, in one pass — because you need all of them, not one.
Twitch requires three: 112, 56 and 28 pixels square. Discord uses 128. Missing any one of the Twitch sizes means the emote cannot be submitted.
Open the Emote & Sticker Resizer and follow the settings and checks below.
Required sizes
| Setting | What it means |
|---|---|
| Twitch | 112 × 112, 56 × 56, 28 × 28 — all three required |
| Discord | 128 × 128 |
| Format | PNG with transparency |
| Source should be | Square, and at least 112 px |
| Why three sizes | Chat renders the smallest one |
| Scaling | Down only — never upscale an emote |
| Privacy | Processed in your browser — never uploaded |
How to use it
- Start from a square image at least 112 px, ideally larger.
- Choose the platform pack.
- Download every size and upload the full set.
A practical quality check
Design for the 28-pixel version, because that is the one people actually see in chat. Fine detail, thin outlines and small text all disappear at that size — an emote that reads perfectly at 112 can be an unrecognisable smudge in a fast-moving chat. Check the smallest export before submitting.
Common questions
Why does Twitch need three sizes?
Different contexts render at different scales — chat uses the smallest, the emote picker and hover previews use the larger ones. Twitch does not scale on your behalf, so all three must be uploaded.
My emote was rejected for the wrong size.
The dimensions must be exact. 112 × 112 means precisely that, not 110 or 115, and the image must be square. This produces exact sizes, which is the point of using it rather than resizing by hand.
Can I upload a small image and let this enlarge it?
You can, but do not. Upscaling invents pixels and produces a soft, blocky emote. Start at 112 or larger — ideally draw at 512 and let everything scale down.
Does it keep transparency?
Yes, PNG transparency is preserved. That matters because emotes appear on both light and dark chat backgrounds, and one with a baked-in white square looks broken on half of them.
