—About ICO Generator
The ICO Generator builds a single .ico file containing several icon sizes from one source image, letting you choose which sizes to include. It is aimed at developers who need a classic multi-size icon for an application or site.
A proper .ico bundles multiple resolutions so the right one is shown in each context. Generating it locally produces that bundle without uploading your artwork.
Step by step
- Drop a source image, ideally square and high resolution.
- Choose which icon sizes to include in the file.
- Preview the generated sizes.
- Download the single .ico containing them all.
What it offers
- Multi-size .ico output from one image
- Selectable icon sizes
- Per-size preview
- Icon built on your device
Tips for best results
- Start from a square image at least 256 px so the largest icon stays sharp.
- Include 16 and 32 px sizes for crisp small-scale display, plus larger ones for modern uses.
- Use simple, high-contrast artwork; fine detail disappears at 16 px.
