SVG to ICO — Create a Favicon from Your Logo
Convert your SVG logo or icon into a multi-size favicon.ico file. Generates 16×16, 32×32, 48×48, and 256×256 sizes — everything browsers and operating systems need for your website's favicon. Free, instant, browser-based.

How SVG favicon conversion works
SVG (Scalable Vector Graphics) is the ideal source format for a favicon — it's resolution-independent, meaning it renders perfectly at any size without pixel loss. This tool uses your browser's built-in SVG rendering engine to draw your logo at each required icon size, then packages those renders into a standard ICO file that browsers and operating systems know how to use.
Why ICO embeds multiple sizes
An ICO file is a container holding several images at different resolutions. When the operating system needs a specific size, it picks the closest match from the container:
- 16×16 — browser tab icon (the tiny favicon visible next to the page title)
- 32×32 — Windows taskbar, higher-DPI browser tabs
- 48×48 — Windows desktop shortcut icons and file explorer
- 256×256 — Windows high-DPI file explorer, some application contexts
Without multiple sizes, Windows upscales from the smallest available — resulting in blurry, pixelated icons. Having all four sizes ensures your favicon looks crisp in every context.
favicon.ico vs favicon.png — which should you use in 2026?
Modern best practice is to serve all three:
- favicon.ico at the site root — covers old browsers, Windows file integration, bookmarks
- <link rel="icon" type="image/png" href="/favicon-32x32.png"> — modern browsers prefer PNG
- <link rel="icon" type="image/svg+xml" href="/favicon.svg"> — Chrome, Firefox, and Safari support SVG favicons natively; they scale perfectly and support `prefers-color-scheme` for dark mode icons
This tool generates the favicon.ico. Keep your original SVG as favicon.svg in your public folder and reference it in your HTML <head> for modern browsers. Have a PNG logo instead of SVG? Use PNG to ICO.
Frequently Asked Questions
Does favicon.ico need multiple sizes?
Yes. ICO files embed 16×16 (browser tab), 32×32 (taskbar), 48×48 (desktop shortcut), and 256×256 (high-DPI file explorer). This tool generates all four sizes from your SVG in a single .ico file.
Can I use an SVG directly as a favicon?
Yes — modern browsers support <link rel="icon" type="image/svg+xml" href="/favicon.svg">. But .ico is still needed for older browsers (IE 11, older Edge), Windows file explorer, and Apple bookmark icons. Use both.
What SVG canvas size should my logo be?
Use a square viewBox in your SVG (e.g. viewBox="0 0 100 100" or viewBox="0 0 512 512"). Rectangular logos will be letterboxed — white or transparent bars appear on the sides. For best results, design a square version of your logo for the favicon.
Will transparency be preserved from my SVG?
Yes. SVG backgrounds are transparent by default. The PNG images packed inside the ICO file support full alpha transparency — your favicon will have a transparent background.
Is my SVG uploaded to a server?
No. The entire conversion — SVG rendering and ICO encoding — runs in your browser using the Canvas API and the Web File API. Your SVG file never leaves your device.
