What is the Favicon Generator?

The ByteTools Favicon Generator turns a single logo or image into every icon a modern website needs: a classic favicon.

  • PNG icons: 16, 32, 48, 180 (Apple), 192 and 512 px (Android/PWA)
  • Copy-ready <link rel="icon"> HTML snippet
  • Standard file names that servers and manifests expect
  • Center-crops rectangular images to a square
  • 100% private — your logo never leaves your browser

About the Favicon Generator

The ByteTools Favicon Generator turns a single logo or image into every icon a modern website needs: a classic favicon.ico containing 16, 32 and 48 pixel versions, PNG icons at 16, 32 and 48 px, a 180 px apple-touch-icon for iOS home screens, and 192/512 px icons for Android and PWA manifests.

It also writes the matching HTML for you — a copy-ready block of <link> tags using the standard file names — so wiring the icons into your <head> takes seconds. Upload a square image of 512 px or larger for the sharpest results; rectangular images are center-cropped to a square automatically.

The whole pack is generated 100% locally in your browser, including the .ico file, which is assembled byte-by-byte on your device. Your logo is never uploaded anywhere.

Frequently asked questions

What favicon sizes does a website need in 2026?

A practical set is a favicon.ico with 16/32/48 px for legacy browsers and address bars, a 180×180 apple-touch-icon for iOS, and 192×192 plus 512×512 PNGs for Android home screens and PWA install prompts. This tool generates exactly that set.

Is ICO format still required for favicons?

Strictly no — every modern browser accepts PNG favicons. But favicon.ico at the site root is still requested automatically by browsers, old bookmarking tools and some crawlers, so shipping one remains the safest, zero-cost choice.

What image should I upload for the best favicon?

Use a square PNG of at least 512×512 with a simple, bold mark — fine detail vanishes at 16 px. Transparent backgrounds are preserved in all the PNG sizes and inside the ICO.

Where do I put the generated favicon files?

Upload them to your site's root (or any folder, if you adjust the href paths) and paste the provided <link> tags into the <head> of your pages. favicon.ico specifically should live at the domain root, because browsers request /favicon.ico by convention.

How is the .ico file created without a server?

The tool writes the ICO container format by hand in JavaScript — an ICONDIR header plus one directory entry per size — and embeds the PNG-compressed images inside, which every modern platform supports. It all happens locally in your browser.
