Generate SVG favicon markup from emoji or text characters

Type an emoji or a single character, pick a background color, and the generator emits an inline SVG you can drop into your <head> as a favicon. Modern browsers render SVG favicons crisply at any size — no more 16x16 ICO files and no separate apple-touch-icon if you don't need one.
The output is a complete <link rel="icon" type="image/svg+xml"> tag with the SVG inlined as a data URI. Paste it into your HTML and the favicon shows up on next reload, no file hosting required.
For projects that still need to support older Safari or browsers without SVG favicon support, generate a fallback PNG separately and add a second link tag with rel="alternate icon".
The generated SVG is small — typically under 500 bytes for an emoji favicon. Structure: a <svg> root with viewBox="0 0 100 100", an optional <rect> background fill, and a <text> element centered at 50,50 with text-anchor="middle" and dominant-baseline="central". The text element holds the emoji. Browsers render the SVG at whatever size the favicon slot needs, and the emoji rasterizes from the OS's emoji font at the right resolution.
Worked example: input the rocket emoji and a #1e293b background. Output is roughly: <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 100"><rect width="100" height="100" fill="#1e293b"/><text x="50" y="50" font-size="70" text-anchor="middle" dominant-baseline="central">rocket</text></svg>. Wrap it in a data URI inside the link tag and paste into <head>. The browser tab now shows your rocket on a slate background, sized appropriately for whatever slot it lands in.
Where it falls short: emoji rendering is OS-dependent. Apple emoji look glossy and detailed; Windows emoji look flatter; older Android skins ship a third style. The SVG file is identical everywhere — what differs is the system emoji font that paints the glyph. If brand consistency matters more than convenience, use an actual SVG path of your logo or a font glyph from a webfont you control. Also: some embedded contexts (RSS readers, certain email clients) don't fetch SVG favicons at all and fall back to the default browser icon. Add a PNG fallback if those contexts matter.
Browser favicon support timeline (rough): Chrome and Firefox added SVG favicon support around 2018-2020. Safari held out longer for regular tabs, with full support landing around Safari 16. Edge follows Chromium. For 99%+ of modern users SVG favicons work; for legacy browsers and embedded contexts (RSS readers, certain crawlers) ship a PNG fallback at 32×32 alongside the SVG link. Two link tags cover everyone.
