Favicon GeneratorFAQ
How many favicon sizes do I actually need?+
Minimum: multi-size .ico (16/32/48) + 180 apple-touch-icon. Recommended: add 192 and 512 for PWA.
Can one image work for all sizes?+
Yes — start from 512×512 or SVG and export every size programmatically. Never upscale a tiny logo.
Which size matters most for SEO?+
Google uses at least 48×48 in search. Ship 48 inside your .ico and as a standalone PNG.
