Frequently asked questions

While a square is best, non-square images are automatically center-cropped before being downsized to prevent distortion.

Yes, if you upload a transparent PNG, the resulting favicon will correctly maintain that transparency in the browser tab.

While modern sites often use PNGs or SVGs, a fallback `favicon.ico` at the root is still a best practice for legacy systems and RSS readers.

Downscaling a complex photo to 16 pixels inevitably loses detail; for best results, use a simple, high-contrast logo.
