Favicon Generator

Generate the standard favicon sizes (16, 32, 48, 180, 192 and 512 pixels) from a single square image.

Free No signup Runs in your browser — nothing uploaded

What it does

Favicon Generator works on JPG, PNG and WEBP images and writes a new file; the one you dropped in is untouched. Every favicon size from one image.

When you need it

Usually because something downstream has an opinion: a profile photo that must be square, a marketplace that rejects anything over a certain width, a print that needs the right proportions, or a phone photo that arrived rotated.

Limits and caveats

Enlarging an image cannot add detail that was never captured, so scaling up softens it. Saving to a lossy format re-encodes the pixels, which is worth doing once rather than repeatedly on the same file. Everything happens in your browser, so the file never leaves your device.

How to favicon generator

  1. Drop or choose your JPG file.
  2. KIVO processes it instantly — no waiting for uploads.
  3. Download the result. That's it.
