Resize Image to 512×512

Resize to 512×512 for Discord server icons, custom emojis, and the largest required Progressive Web App icon. As another power of two (512 = 2^9), it downsizes cleanly and stays lightweight. Many platforms treat 512×512 as the sweet spot between crisp detail and small file weight for square avatars.

The 512 avatar standard

Discord recommends 512×512 for server icons and role emojis, and Android's PWA manifest lists a 512×512 icon as the high-resolution entry for the install prompt. Hitting the exact size keeps these assets sharp on every device.

It also suits game profile avatars and forum badges. Because the resize is done in the browser, a personal avatar or a game asset in progress never gets uploaded anywhere first.

Balancing detail and weight

512×512 holds 262,144 pixels, enough for clear features on an avatar but small enough that a PNG usually stays under 500 KB. That balance is why app manifests favor it.

Since it halves cleanly to 256 and 128, a single 512 master can supply an entire icon set. Keep the design centered and simple, as fine detail vanishes once the icon shrinks in a chat sidebar.

Frequently asked questions

What size should a Discord server icon be?

512×512 is the recommended size. Discord displays it as a circle, so keep key elements centered and away from the corners.

Why do PWAs need a 512×512 icon?

The web app manifest lists 512×512 as the large icon used for the Android install banner and splash screen. Providing it ensures the app looks sharp when installed.

Is 512×512 better than 256×256 for an avatar?

512 carries more detail and downscales cleanly to 256 if needed. Starting larger and letting the platform shrink it looks better than uploading an already-small 256 image.
