Summary
Upload an SVG file and instantly download a multi-size ICO file (16, 32, 48 px) — no server, no upload, 100% in your browser.
How it works
- Select or drag-and-drop your SVG file onto the upload area.
- The browser renders the SVG onto an HTML Canvas at 16, 32, and 48 px.
- Each canvas is read back as raw RGBA pixel data.
- A pure-JavaScript ICO builder assembles the binary file with a correct ICO header, directory entries, and embedded BMP bitmaps.
- Click "Download ICO" to save the resulting .ico file to your device.
Use cases
- Create a favicon.ico for a website from an SVG logo.
- Generate a Windows application icon from a vector source.
- Quickly preview how an SVG looks at small pixel sizes.
- Bundle multiple icon resolutions into a single ICO for legacy browser support.
- Convert brand SVG marks to ICO without installing desktop software.
- Prepare multi-size icons for Electron or desktop app packaging.
