Favicon Generator

Upload one image and instantly get every favicon size you need — from a 16px tab icon up to a 512px PWA icon, plus a 180px Apple touch icon. Save each PNG or grab them all as a ZIP, all in your browser.

Everything runs in your browser — your image is never uploaded. Sizes are drawn onto a square canvas with a centered cover fit.

Understanding the Favicon Generator

The Favicon Generator turns a single image into a complete set of favicons, right in your browser. Upload a PNG, JPG, WebP, or SVG and it draws your artwork onto square canvases at seven sizes — 16, 32, 48, 64, 180, 192, and 512 pixels — covering everything from a tiny browser-tab icon to a 180px Apple touch icon and a 512px progressive-web-app icon. Each size shows a live preview with its own Save PNG button, and a single Download all (ZIP) button bundles every file at once. Optional controls let you fill transparent areas with a background color and add rounded corners. Nothing is uploaded; the image never leaves your device.

How it works

Pick or drop an image and the tool reads it locally with the browser's Image API, never sending it anywhere. For each target size it creates an off-screen canvas, optionally paints your chosen background color and clips rounded corners, then scales your source using a centered cover fit so the square is filled without distortion and any overflow is cropped. The canvas is exported to a PNG blob via canvas.toBlob, shown as a preview, and offered as a download. The Download all button loads JSZip on demand, adds every PNG to an archive, and saves it as favicons.zip. A ready-to-paste <link rel="icon"> snippet shows how to wire the files into your site.

Worked example

Say you upload a 1024×1024 PNG logo. The tool generates seven PNGs in one pass: favicon-16x16.png and favicon-32x32.png for browser tabs, favicon-48x48.png and favicon-64x64.png for the desktop and high-DPI tabs, favicon-180x180.png as the Apple touch icon for iOS home screens, and favicon-192x192.png plus favicon-512x512.png for Android and PWAs. You toggle a white background to flatten transparency, click Download all (ZIP), and get a single favicons.zip containing all seven files ready to drop into your site root.

Tips & common mistakes

  • Start with a square image at least 512×512 px so even the largest icon stays crisp; non-square images are center-cropped to fit.
  • Keep the artwork simple and bold — at 16px fine details and thin text disappear, so favor a single strong shape or letter.
  • Enable the background color for logos with transparency if you want a solid tile instead of a see-through icon on busy backgrounds.
  • Use the rounded-corners toggle to match iOS and Android home-screen styling, though most platforms already apply their own masking.
  • After downloading, place the PNGs in your site root and add the <link rel="icon"> and apple-touch-icon tags shown in the tool.
  • A modern set of PNGs covers virtually all browsers; you only need a classic favicon.ico for very old clients.

Frequently Asked Questions

What favicon sizes do I get?

Seven square PNGs: 16, 32, 48 and 64px for browser tabs and the desktop, a 180px Apple touch icon for iOS home screens, and 192 and 512px icons for Android and progressive web apps.

Can I download them all at once?

Yes. Every size has its own Save PNG button, and the "Download all (ZIP)" button packages all seven PNGs into a single favicons.zip — built in your browser with no upload.

Is my image uploaded to a server?

No. The image is read and resized entirely in your browser using a canvas, so nothing ever leaves your device. Closing the tab clears everything.
