Discord custom emoji requirements
Discord publishes clear guidelines for custom emoji. EmoteTools follows those specs so your export is ready to upload.
"Dimensions: 128x128. Bigger or smaller will work, but 128x128 is juuuust right."— Discord — How to Make and Use Custom Emoji
Discord also notes a practical file-size ceiling for custom emoji. Keeping exports at 128×128 and under 256 KB is the most reliable path for crisp chat display.
FAQ
What size should Discord emoji be?
Discord recommends 128×128 pixels for custom emoji. Larger or smaller images can be uploaded, but 128×128 is the optimal source size for crisp display in chat.
What is the Discord emoji file size limit?
Custom emoji must be 256 KiB (256 KB) or smaller. This tool tries to compress oversized outputs while keeping 128×128 dimensions.
Which formats does Discord accept?
Discord accepts JPEG, PNG, GIF, WebP, and AVIF. Animated emoji typically use GIF or WebP and require server boosts or Nitro for animated slots.
Are my files uploaded to a server?
No. EmoteTools resizes images entirely in your browser. Nothing is sent to our servers.
Should I use a transparent background?
Yes for most emoji. PNG with transparency blends cleanly into Discord’s chat backgrounds. This tool preserves transparency when you upload PNG, GIF, or WebP with an alpha channel.
