Questions

Frequently Asked Questions

Vector XML rasterization, binary 22-byte ICO header assembly, and instant local export.

1

Can I use an SVG file directly as a favicon in all browsers?

While modern browsers support SVG favicons, legacy browsers, desktop Windows taskbars, and older mobile platforms still require a standard .ico file for consistent display.
2

How does the converter generate Windows ICO files from vector SVG?

Our in-browser engine rasterizes the SVG vector paths onto an HTML5 canvas at high-DPI 256x256 resolution, then wraps the resulting PNG bitstream in a standard 22-byte ICO binary header.
3

Will transparent backgrounds in my SVG be preserved in the ICO icon?

Yes. Our pipeline supports full 32-bit RGBA transparency, ensuring smooth alpha cutouts without black bounding boxes or harsh pixelated edges.
4

Are my SVG graphics or brand logos uploaded to an external server?

No. The entire vector parsing, canvas rendering, and binary packaging sequence executes 100% client-side in your local browser memory. Your assets never leave your device.
5

What dimensions are included in the generated ICO file?

The tool generates a master 256x256 high-resolution ICO container that operating systems and browser tabs automatically downsample to 16x16, 32x32, and 48x48 as needed.
6

Can I convert multiple SVG icons at once and download a ZIP?

Yes. You can queue multiple SVG graphics simultaneously. Converted .ico files can be saved individually or exported together in an uncompressed ZIP archive with one click.
