Discord Sticker Maker

Stickers must be exactly 320x320 pixels and at most 512 KB. Unlike emoji, where the dimensions are a recommendation, the sticker size is enforced - an image of any other dimensions is rejected outright.

Accepted formats are PNG for static stickers and APNG or Lottie for animated ones. Lottie is a JSON-based vector format and is restricted to servers with boost level 2 or higher; GIF is not accepted at all, which surprises people coming from emoji.

Every sticker needs a name and at least one related standard emoji, which is what Discord uses to suggest it in the picker. That tag is required rather than optional.

A sticker is sent as its own message rather than inline with text, and it renders far larger than an emoji. That makes them reaction pieces rather than punctuation - a sticker interrupts a conversation where an emoji decorates it.

Server sticker slots are separate from emoji slots and are considerably scarcer, starting at five and increasing with boost level. Because of the fixed 320x320 canvas and the size on screen, sticker artwork needs to work as a standalone image rather than a 32-pixel icon.

Emoji work inline inside a message; stickers replace the message. That makes stickers better for reactions with personality and emoji better for quick annotation.

A matching set of three or four stickers in one style does more for a server's identity than a dozen unrelated images.
