IMAGE to ICO Converter

Quick answer: Generate a multi-size .ico favicon from any square image. Open IMAGE 转 ICO — everything runs locally in your browser, and files never leave your device.

Steps

1. Upload a square PNG/JPG to the ICO converter.
2. Select sizes (16/32/48/256).
3. Download the .ico and deploy it to your site root.

Important notes

• Crop the source square first — non-square sources distort or pad.
• Include 16 and 32 px at minimum; add 48 for high-DPI contexts.
• Modern browsers accept plain PNG favicons; .ico wins for legacy browsers and desktop shortcuts.

Common questions

Transparency kept? Yes, from PNG sources.

SVG source? Rasterize to a high-res PNG first, then convert.

When to use this

Test the favicon in both a normal tab and a pinned tab — pinned tabs use the smaller sizes and reveal scaling artifacts.
