Frequently Asked Questions
Everything you need to know about ICO conversion
What is an ICO file?
Most websites should include at least 16x16, 32x32, and 48x48 sizes. Adding 64x64 or 256x256 helps with high-DPI contexts and broader platform behavior.
What sizes should I include?
Yes. Start from a square source image with strong contrast and simple shapes. Tiny favicon sizes hide fine details, so clear silhouettes work better than complex artwork.
Can I convert transparent PNG to ICO?
You can use JPG or PNG sources, but PNG is generally better for sharp edges and transparent backgrounds before ICO packaging.
Is this converter free?
After conversion, place the favicon in your site root and reference it in HTML head tags. Also test browser cache refresh behavior during rollout.
Are my images stored on your servers?
Yes. Favicons improve brand recognition in tabs, bookmarks, and search snippets. They are small assets, but they contribute to polish and trust signals.
