About this tool
SVG is a vector format produced by design tools, so it scales to any size cleanly. An ICO holds several sizes in one file, so a browser or desktop can pick the right one instead of scaling a single image badly.
This tool converts SVG to ICO entirely in your browser. The image is decoded, drawn, and re-encoded on your device, so nothing is uploaded and the size of the file costs you no waiting.
Supported formats and limits
- Input
- .svg
- Output
- .ico (image/x-icon)
- Output name
- The original name with the new extension, for example photo.svg becomes photo.ico.
- File size limit
- 50 MB
- Processing
- In your browser. The file is not uploaded.
How to use it
- Choose a .svg file, or drag one onto the page.
- Icon sizes 16, 32, and 48 pixels are written into the one file.
- Set an output size if the SVG does not carry one, or a scale to render it larger.
- Select Convert, then download the ICO file.
Limitations
- An SVG with no width and height of its own needs an output size, because there is nothing to derive one from.
- Fonts and images the SVG references from elsewhere are not fetched, so text in an unusual font may render with a substitute or not at all.
- Scripts, event handlers, and external references are stripped before the file is rendered.
- Icons are square. A rectangular source is fitted into the square, which changes its proportions.
- An icon can be at most 256 pixels, which is a limit of the format.
- Metadata is not preserved. EXIF fields, including camera settings and GPS location, are dropped, which is a privacy benefit but worth knowing if you rely on them.
- Colour profiles are not preserved, so an image in a wide-gamut profile may shift slightly.
Frequently asked questions
- Is my image uploaded?
- No. The conversion runs entirely in your browser. The image never leaves your device and no request carrying it is made.
- Will this work as a favicon?
- Yes. The file holds 16, 32, and 48 pixel versions in one icon, which is what browsers expect at /favicon.ico, and each size is rendered from your image rather than scaled from one another.
- Why is my SVG asking for a size?
- Because it declares only a viewBox and no width or height, so there is no pixel size to use. Give a width, a height, or a scale.
- Is it safe to convert an SVG I did not write?
- Yes. SVG can carry scripts and references that fetch from other sites, so the markup is parsed and stripped of scripts, event handlers, and external references before anything is rendered, and rendering happens in a context where scripts do not run.
- Can I resize while converting?
- Yes. Set a width, a height, or both. With proportions kept, one dimension is derived from the other, and giving both fits the image inside that box rather than distorting it.
