Your server icon shows up everywhere — the server list, invites, search — often at just 48 pixels. Upload big so it holds up wherever Discord shows it larger.
A Discord server icon is shown at a tiny 40–48 pixels most of the time, in a sidebar competing with dozens of other servers — but it also appears considerably larger in server settings, discovery listings, and invite screens. Uploading at 512×512 means it holds up in every one of those contexts, not just the small everyday view.
Open Squeezr and drop in your server logo or artwork.
Turn on Resize, unlock the aspect-ratio lock, and set width and height to 512 × 512.
Choose Crop mode so the full square fills the frame — keep your design centered and simple, since it's displayed as a circle and often viewed at tiny sizes.
Export as PNG if you want a transparent background, or JPG otherwise.
Upload it as your server icon in Server Settings.
Skip the manual math — open Squeezr with this preset already dialed in.
Open Squeezr preset to 512×512 →Because Discord shows the exact same icon at wildly different sizes across the app, uploading small (near the 128×128 minimum) means it looks fine at 48px but noticeably soft the moment someone opens server settings or an invite preview where it's shown much larger. 512×512 covers every placement without needing separate versions.
Even though you're uploading at 512×512, remember most members will see your icon at 40–48 pixels in the sidebar nearly every time they use Discord. Bold, high-contrast, simple shapes or initials read far better at that size than a detailed illustration or small text.
