Everything you keep needing on Discord, one link. Pick what you want to do — all free, no account, no watermark.
Custom emoji: 128×128, max 256KB (animated emoji hit this limit fast — use fewer frames or a shorter loop). Sticker: 320×320, under 500KB. Server icon: 512×512. Role icon: 64×64. Profile banner: 600×240. Server banner: 960×540 or larger. Upload limit for video: keep clips short and 720p if you don't have Nitro.
What size is a Discord emoji? Custom Discord emoji are 128×128 pixels, with a 256KB file limit — that limit is what usually breaks animated emoji first, since every extra frame adds to the file size. Stickers are 320×320 pixels under 500KB, server icons 512×512, profile banners 600×240 and server banners at least 960×540.
How do I get a video under Discord's upload limit? Compress it before uploading. The "under 10 MB" mode above takes any clip, lets you pick a 10 or 25 MB target, and returns an MP4 guaranteed under that size — free, no watermark, no account. It keeps the resolution as high as the target allows.
How long can a Discord soundboard clip be? Discord soundboard clips are capped at 5 seconds. Trim your clip first and clean up the noise so it still reads clearly once it's short — the audio cleanup mode plus the soundboard-clip mode above cover both steps.
The seven jobs above split across three places, and it's worth knowing which before you drop a big file in. Resizing to every Discord size and shrinking an emoji or sticker under the limit both happen on your device, in the browser tab you're looking at right now — nothing is uploaded, so there's no file-size ceiling beyond what your phone or laptop can hold in memory. Cutting a subject out and turning a clip into an animated emoji use a GPU on our side, because that kind of image work needs more compute than a browser can offer; those come back once the queue clears. Compressing a clip under the upload limit and cleaning up audio run on a regular server rather than a GPU, since both are closer to file conversion than to image generation. None of the three is "better" — they're different jobs, and the toolkit routes each one to wherever it actually gets done.
