Frequently Asked Questions
What's the difference between ICO and PNG for favicons?
While modern browsers can use PNG for favicons, ICO remains the most universally compatible format. ICO files can also contain multiple sizes in one file, which PNG cannot do.
What size should my favicon be?
A proper ICO file should contain multiple sizes. The most important are 16×16 (for browser tabs), 32×32 (for shortcuts), and 192×192 or 256×256 (for high-resolution displays). Our converter automatically creates all necessary sizes.
Can I use a JPEG/JPG as a favicon?
JPEG images don't support transparency, which makes them less ideal for favicons. Our converter can convert JPG to ICO, but we recommend starting with PNG or SVG files with transparency for best results.
How do I make my favicon display on all browsers?
Using a standard favicon.ico file in your website's root directory ensures maximum compatibility. For complete coverage, implement both the ICO format and additional formats as shown in our implementation guide.
Can I convert my logo to ICO?
Yes! Our tool is perfect for converting logos to favicon format. For best results, use a simple, recognizable element of your logo that remains clear even at small sizes.
Why does my website need a favicon?
Favicons enhance brand recognition, make your site look professional, help users identify your site in tabs and bookmarks, and contribute to the overall user experience of your website.
