Frequently asked questions

Do I still need a favicon.ico file?

Rarely. Every current browser reads PNG favicons via link tags. A root favicon.ico only matters for very old browsers and for requests that bypass your HTML entirely.

What size should the source image be?

At least 512-512 and square. Icons are downscaled, never upscaled, so a small source will look soft at the larger sizes.

How to use the favicon generator

  1. 1Select your source image — the file stays on your device and is never uploaded.
  2. 2Choose the icon set.
  3. 3Press Run, then download the result when it is ready.
