About SVG to ICO

Where SVG files come from

Logos are usually made as SVG, but Windows shortcuts, desktop apps, and the classic favicon.ico need an ICO file holding several small sizes. Shrinking one big picture makes tiny sizes blurry; drawing each size from the SVG keeps them sharp.

What changes

  • The SVG is drawn separately at 16, 32, 48, and 256 pixels, and all four go into one ICO file as PNG pictures.
  • Non-square logos are centred in a transparent square.
  • Transparency is kept at every size.
  • Thin lines and small text may vanish at 16 pixels; simplify the logo for tiny sizes if that happens.

Measured

Our test logo (an SVG of 1200 by 800 with a gradient, shapes, and text) made into an icon in Chrome on a laptop. Phone timings are still to be measured.

In your browser

Every browser draws SVG itself, but only on the page, not in a background worker. So each size is drawn on the page, with scripts and outside links removed first, and the icon is assembled in a worker. Nothing extra is downloaded.

Limits

  • The sizes are fixed at 16, 32, 48, and 256 pixels.
  • Icons store each size as PNG, which Windows Vista and later and every browser read; Windows XP can't.
  • Fonts that aren't on your device or embedded in the SVG are replaced.

Other options

  • SVG to PNG: a single PNG at any size, for apple-touch-icon and app stores.
  • PNG to ICO: make an icon from a PNG instead.
  • ICO to PNG: the reverse, to take the sizes out of an icon.

Questions

Which sizes are inside the icon?

16, 32, 48, and 256 pixels square, the sizes Windows and browsers use for tabs, the taskbar, desktop shortcuts, and file lists.

Are my files uploaded?

No. Your files are processed on your device. We never upload them.

Why is SVG a good source for an icon?

Each size is drawn fresh from the vector shapes, so the 16-pixel version is as crisp as it can be, instead of a large picture shrunk down and blurred.

My logo isn't square. What happens?

It is fitted inside each square and centred, with the rest left transparent, so nothing is cropped or stretched.

Can I use it as a website favicon?

Yes. Save it as favicon.ico in your site's root folder, or link to it from your pages. Every browser reads ICO files.

Is it safe to convert an SVG from someone else?

Yes. The SVG is drawn as a picture, which never runs scripts or loads links, and scripts and outside links are removed before drawing.
