Best practices for website icon exports
Different image formats serve different purposes. JPEG is great for photographs with small file sizes. PNG preserves transparency and quality for graphics. WebP and AVIF offer the best of both worlds with smaller sizes. Our converter uses ImageMagick WASM technology to handle all these conversions right in your browser, ensuring your images stay private while giving you professional-grade results.
Frequently Asked Questions
Common questions about image format conversion
What size PNG should I use for a favicon?
Common favicon sizes include 16×16, 32×32, and 48×48. You can prepare PNG files at those sizes and convert them to ICO for best results.
Can I put multiple sizes into one ICO file?
Yes. An ICO file can contain several sizes so your icon looks sharp on different screens. The converter can pack multiple PNG sizes into one favicon.
Will the background stay transparent?
Yes. ICO supports transparency, so logos with transparent backgrounds will keep that look in most modern browsers.
