Open Favicon Size Guide 2026The essential favicon sizes
16×16 (tab) is the minimum; 32×32 covers Windows taskbar and most bookmark bars; 48×48 is the classic Windows and legacy standard; 180×180 is the Apple Touch Icon. Modern guidance: ship SVG for modern browsers plus PNG 32×32 and 180×180 for everything else.
How to generate every size at once
- Open the Favicon Generator.
- Upload a square image or logo (512×512 or larger).
- Download the full set — 16, 32, 48, 64 and 180px PNGs, plus SVG from vector sources.
- Reference them in `<link rel="icon">` and the apple-touch-icon tag.

Sizes are cheaper than they look
A 16×16 favicon fits comfortably under 1KB — the whole set is usually smaller than a single JPEG thumbnail. Tiny files, big branding consistency across tabs, bookmarks, and home screens.

Frequently Asked Questions
What is the most important favicon size?
32×32 for desktop browsers plus 180×180 for iOS. Add SVG for retina-ready scale on modern browsers.
How big should my favicon file be?
Under 10KB for all PNG sizes combined is normal. Oversized favicons delay tab loading unnecessarily.
Can one image generate all sizes?
Yes — a single 512×512 logical image downscales cleanly to every PNG size. Squares work best; logos with wide margins need a crop first.
