Frequently asked questions
What sizes does a website favicon need in 2026?
A practical modern set: favicon.ico (16+32+48), favicon-16x16.png, favicon-32x32.png, apple-touch-icon.png (180×180), and android-chrome icons at 192×192 and 512×512 for the web manifest.
What image should I start from?
A square PNG or SVG of at least 512×512 with a simple, high-contrast design. Fine details disappear at 16×16, so bold shapes work best.
Is the favicon.ico file real ICO format?
Yes — the tool builds a standards-compliant ICO container with embedded PNG images at 16, 32 and 48 pixels, which every modern browser accepts.
