This tool turns a logo or image into a complete favicon set: a classic favicon.ico (bundling the 16x16, 32x32, and 48x48 sizes browsers expect), plus apple-touch-icon.png for iOS home screens and android-chrome-192x192.png/512x512.png for Android and PWA install prompts. Upload an image, then drag the corners of the square selection box to frame exactly the part of your logo you want — the rest is trimmed, not squashed. Leave the background transparent (the usual favicon convention) or pick a solid color to fill in behind it. Every file is generated entirely in your browser, along with a ready-to-paste HTML snippet for your site's <head>.
