ImgWrench's SVG to ICO converter turns a vector logo into a Windows .ico file. Each size you pick, from 16 to 256 pixels, is drawn from the SVG at exactly that size, so small icons keep crisp edges instead of being scaled down from one large bitmap.

How to convert SVG to ICO

  1. Drop one or more SVG files into the tool above.
  2. Keep the default sizes, or tick the ones you need.
  3. If a drawing isn't square, choose Contain or Cover.
  4. Download each .ico, or all of them as a ZIP.

Which sizes to include

Windows looks for an exact size first and scales the next size down when there isn't one. Microsoft recommends at least 16, 24, 32, 48 and 256 pixels; Windows can also use 20, 30, 36, 40, 60, 64, 72, 80 and 96 at higher display scaling.

Tips for SVG icons

  • Outline your text. Fonts your SVG doesn't embed won't load inside an image; convert text to paths first.
  • Check the 16px preview. Fine detail that looks great at 256 can turn to mush at 16.
  • Set a viewBox. It tells every tool, including this one, the drawing's true shape.

Why ImgWrench

  • Vector-sharp at every size. No scaling from a single bitmap.
  • Every size Windows uses. Pick any of the 14 sizes Microsoft lists.
  • Private by design. Your files never leave your device.

Frequently asked questions

Why convert from SVG instead of PNG?

An SVG is a vector, so ImgWrench draws it fresh at each size. A PNG has to be scaled down, which can blur thin lines at 16 or 24 pixels.

What sizes should an ICO file have?

Microsoft says apps should have at least 16×16, 24×24, 32×32, 48×48 and 256×256. Those are checked by default; add more if you need them.

My SVG isn't square. What happens?

Choose Contain to fit the whole drawing with transparent space around it, or Cover to fill the square and trim the edges.

Why does my SVG come out the wrong size or blank?

ImgWrench reads the drawing's shape from the width and height on the svg tag, or from its viewBox. SVGs that load external images or fonts may draw without them, because browsers block outside files in SVG images.

Are my files uploaded anywhere?

No. Everything happens in your browser. Your files are never sent to a server, and you can confirm this in your browser's network tab.
