Frequently asked questions

What is 512×512 used for?
It's a square size used for Discord avatars and server icons, app icons, custom emojis, stickers and game assets.
Why 512 and not a round number like 500?
512, 256 and 1024 are powers of two, which many apps, icon systems and game engines handle most efficiently. 512×512 is the most commonly requested.
Should I use Fill or Fit?
Use 'Fill' for photos and avatars (crops to a centered square). Use 'Fit' for logos or full graphics you don't want cropped: it pads the edges with white.
Can I make a transparent icon?
Yes. If your source is a transparent PNG, choose a size and keep the format as PNG (transparency is preserved unless you pick 'Fit' with a JPEG, which adds white).
Is my image private?
Yes. It's resized in your browser and never uploaded to any server.
