Favicon guides

Short, practical answers to the questions that come up while building an icon set.

• Favicon sizes explained Which files you actually need, what each one answers to, and the legacy sizes you can drop.
• Adding a favicon to WordPress, Shopify and Squarespace The exact path on each platform — and what their built-in uploader quietly leaves out.
• Why your favicon looks blurry Four causes: one-jump downscaling, sub-pixel strokes, deceptive contrast, and too much detail.
• favicon.ico vs favicon.svg What each format is for, how browsers pick, and why SVG-only leaves some visitors iconless.
