Discord Emoji Resizer
Custom Discord emojis are uploaded at 128×128 pixels but spend their lives rendered around 32 pixels in chat — and even smaller in reactions. That gap is why detailed images turn to mush as emojis: the design has to survive a 4× shrink. This tool resizes your art to 128×128, preserves PNG transparency, and keeps the file under Discord's 256 KB cap.

Common uses
- Server admins building a custom emoji set for their community
- Artists preparing commissioned emoji packs for delivery
- Communities turning inside jokes and memes into reaction emojis
- Streamers adapting their Twitch emote art for a Discord server
- Moderators replacing oversized uploads that Discord rejected
Good to know
- Emojis display at about 32 pixels in chat — bold shapes and high contrast survive; fine linework and small text do not.
- Export PNG with a transparent background so the emoji sits cleanly on both dark and light Discord themes.
- Discord caps emoji uploads at 256 KB. A static 128×128 PNG almost never exceeds it; large animated GIFs are the usual offenders.
- Preview your emoji against a dark background before uploading — most Discord users run the dark theme.
- Animated emojis are GIF uploads and need Nitro to use; this tool exports static PNGs.

Frequently asked questions
What size should a Discord emoji be?
128×128 pixels — the upload size Discord has used for custom emojis as of our July 2026 verification. Discord scales it down to roughly 32 pixels for display in chat, so design for the small size.
Why does my emoji look muddy in chat?
At 32 pixels, intricate details blur together. Simplify the design: thicker outlines, fewer elements, stronger contrast. A good test is shrinking the image to 32×32 yourself and checking whether it still reads at arm's length.
What is the file size limit for Discord emojis?
256 KB per emoji when we last verified in July 2026. Static PNGs at 128×128 are typically 10–50 KB, so the limit mainly bites on animated GIFs with many frames.
Do Discord emojis need a transparent background?
It is not required, but strongly recommended. A solid background shows as a visible box around your emoji on whichever theme it does not match. PNG transparency makes the emoji blend into any chat background.
How many custom emojis can a server have?
Servers start with 50 static emoji slots, and server boosts unlock more tiers — that structure was current as of July 2026, though Discord adjusts perks from time to time. Animated emoji slots are counted separately.
