Discord Banner Size Resizer

Discord has two kinds of banner: the server banner at the top of the channel list, shown at 16:9, and the profile banner behind your avatar, which needs Nitro. Discord asks for at least 960 × 540 pixels for a server banner and suggests 1920 × 1080 or larger. This resizer crops or fits your image to those sizes, keeps the part you choose, and draws a guide marking where the server name or your avatar covers the picture.

How to use this tool

1. Choose your image or several images.
2. Pick the server banner (minimum or recommended size) or the profile banner.
3. Crop to fill and set the position, or show the whole image on a colour or blurred background.
4. Check the guide preview: keep text out of the red areas.
5. Download and upload it in Server Settings → Server Banner, or User Settings → Profiles.

Formula

scale = max(target width ÷ width, target height ÷ height) × zoom

The kept window is target ÷ scale, centred on the chosen position. The guide shades the top 30% of a server banner, where the server name is drawn, and a disc around the avatar position of a profile banner. Both are approximate, because Discord's layout differs between desktop and mobile.

Example

A 2560 × 1440 screenshot is already 16:9: scale = max(960/2560, 540/1440) = 0.375, so the whole picture is kept and shrunk to 960 × 540. A 3000 × 3000 square artwork keeps a 3000 × 1688 window instead, the middle 56% of its height.

Discord banner rules

Discord's help centre says the minimum server banner size is 960 × 540 px and recommends 1920 × 1080 or bigger. Server banners need a boosted server (Boost Level 2, or Level 3 for animated banners). Profile banners need Nitro; 680 × 240 px is the size commonly recommended for them, and larger images of the same shape also work. This tool makes still images only; animated banners need a GIF tool.
