Upload one square-ish logo and get the whole standard favicon package back: favicon.ico, every PNG size browsers and phones actually use, site.webmanifest, and the <head> tags to paste in. A non-square source is padded to a centered square, never cropped, so nothing gets cut off.
favicon.ico — multi-resolution (16/32/48px), the classic browser-tab icon.favicon-16x16.png, favicon-32x32.png, favicon-96x96.png — plain PNG fallbacks.apple-touch-icon.png (180×180) — iOS "Add to Home Screen".android-chrome-192x192.png, android-chrome-512x512.png — Android home screen and PWA install icons.site.webmanifest — references the two android-chrome icons; edit name before using if you want an app name shown on install.head-snippet.html — the exact <link> tags to paste into your site's <head>.curl -sS -X POST https://devops.majbase.com/favicon-generator/api \
