favicon.ico vs PNG vs SVG: which format should you use in 2026?
In 2026 the right answer is not one format but a small combination: keep a multi-resolution favicon.ico at your root as the universal fallback, declare PNG icons for crisp high-DPI rendering, and optionally add an SVG icon for browsers that support it. Each format does a job the others can't.

In 2026 the right answer is not a single format but a small combination. Keep a multi-resolution favicon.ico at your root as the universal fallback, declare PNG icons for crisp rendering on high-DPI screens, and optionally add an SVG icon for the modern browsers that support it. Each format does a job the others cannot, and the complete set is still tiny.
favicon.ico - the universal fallback
ICO is a container that holds several resolutions in one file. Browsers automatically request /favicon.ico from your site root even without a link tag, and older clients, feed readers, and some operating-system surfaces still prefer it. Pack 16, 32, and 48 into one ICO and you have a guaranteed baseline. Note that a real ICO is encoded, not a renamed PNG - see PNG to ICO for why.
PNG - crisp, modern, high-DPI
PNG handles transparency and color better than legacy ICO and is what modern browsers prefer when declared in the head. The sizes that earn their place are 16 (tabs/bookmarks), 32 (Retina tabs, taskbar), and a 180 Apple touch icon. Android and PWA use 192 and 512 PNGs from the manifest. Converting from a source image is easy: PNG to favicon.
SVG - sharp at any size, but not sufficient alone
A growing number of browsers accept an SVG favicon, which is razor sharp at any resolution and can even adapt to dark mode with a media query inside the SVG. But you still need an ICO fallback and a raster Apple touch icon, because not every surface reads SVG. Treat SVG as a progressive enhancement, generated alongside the rest: SVG to favicon.
The minimal set that works everywhere
- favicon.ico (16/32/48) at the root - the fallback.
- PNG 16 and 32 declared in the head - crisp tabs.
- apple-touch-icon 180 - iOS home screen.
- PNG 192 and 512 + maskable 512 in the manifest - Android and PWA.
- Optional SVG icon - sharp, theme-aware enhancement.
Generate the whole combination at once
You do not have to assemble this by hand. Drop one image into the Logo2Favicon generator and it outputs the ICO, every PNG size, the Apple touch icon, the Android/PWA and maskable icons, plus the manifest and the exact <head> snippet. For the deeper walkthrough, read the complete favicon guide and the icon size cheatsheet.
Generate your full icon set free
Drop one logo into the generator and download favicon.ico, every PNG size, the Apple touch icon, Android, PWA, and maskable icons, plus the manifest and HTML snippet - all in your browser, nothing uploaded.
