Resize static or GIF emoji to 128×128, or static stickers to 320×320 PNG. Check each output’s file size before uploading. Free; your images stay on your device.
Need a crop, background cleanup or outline? Use the Discord Sticker Maker. GIF input stays an animated emoji; it is not converted to an APNG sticker.

Discord recommends uploading emoji at 128×128 with a 256KB file cap. In chat they render small, so bold shapes and clean outlines win — check the preview above at a squint before uploading. Slack uses the same 128px box on a tighter 128KB budget, so a Discord-ready file may need trimming first — see the Slack emoji spec. This 128px figure is an emoji rule only; it gets misquoted constantly as the avatar size, which Discord never publishes — see Discord PFP size.
Stickers are bigger: 320×320 with a 512KB cap. Static stickers are PNG; animated stickers use APNG. This tool exports a static PNG from a static source and skips the Sticker preset for GIF input. It does not create APNG or silently flatten GIF animation.
If the artwork still needs a crop, simple background cleanup or outline, use the Discord Sticker Maker first.
Drop a GIF and every frame is resized to 128×128 with the original timing, re-encoded and size-checked against the 256KB cap. Nitro users can use animated emoji in any server that has slots free.
The same art usually works on both platforms — toggle the Twitch preset too and get the 112/56/28 ladder in the same download. The main emote resizer handles the full multi-platform pass.
File size is one possible cause: Discord lists a 256KB custom emoji limit. The size badge above flags an oversized export. For a static image, try the Discord emoji compressor to produce and measure a file below that limit.
Yes — drop the original art (ideally the largest version you have) and export the 128×128 Discord preset. Upscaling a 28×28 Twitch export will look blurry; always start from the biggest source.
Working across platforms? The hub compares all seven specs side by side and resizes them from a single upload.
