WHAT IT DOES

One source image, every favicon file a site actually needs.

Choose a PNG, JPEG, WebP, or validated SVG and build a local package containing a multi-size ICO, browser PNGs, an Apple touch icon, Android icons, a web manifest, and matching link markup. Contain keeps the whole source with transparent padding; Crop to cover fills each square and trims the edges.

Why use it?

Use it to produce the related icon sizes and HTML references a website needs from one source image.

How to use this tool

  1. Choose an image or self-contained SVG with enough detail for the largest output.
  2. Choose Contain to keep the full design or Crop to cover to fill the square. Inspect how the design reads at the smallest icon sizes.
  3. Build the package, then download and review its icons, manifest, and HTML fragment.
  4. Place the files at your chosen public paths and adjust the references accordingly. The download does not update a website or invalidate an already cached favicon.

Details and limitations

  • favicon.ico contains separate 16, 32, and 48 pixel PNG images in a standard ICO directory instead of a renamed single PNG.
  • The ZIP also includes 16 and 32 pixel browser icons, a 180 pixel Apple touch icon, 192 and 512 pixel web-app icons, site.webmanifest, and a matching HTML fragment.
  • Every size is rendered independently from the decoded source so the browser does not repeatedly scale an already reduced icon. Transparent pixels are preserved.
  • The package is assembled with a deterministic local ZIP writer and can be reviewed before either the ICO or full archive is downloaded.

COMMON QUESTIONS

Favicon Converter questions

What files are in the favicon package?
It contains favicon.ico; 16×16 and 32×32 PNG favicons; a 180×180 Apple touch icon; 192×192 and 512×512 Android icons; site.webmanifest; and a small HTML file with the matching link tags.
Should I use Contain or Crop to cover?
Contain keeps the entire source and centres it with transparent padding when it is not square. Crop to cover fills the square but trims the longer dimension. The previews make that decision visible before download.
Can I use an SVG source?
Yes, after the same local safety validation used by SVG Viewer. Active and external SVG constructs are refused before the browser renders the artwork.
