Favicon Generator
Home » Image Tools » Favicon Generator
Upload a logo, check it at real tab sizes, and download PNG icons plus a real favicon.ico.
PNG, JPG, WebP, or basic SVG. A square logo of 512 pixels or more works best.
PNG keeps transparency, and the ICO uses PNG payloads so transparency is kept there too. If no image is loaded, or the image cannot be drawn, a clear error is shown and nothing is downloaded.
A favicon is the small icon browsers show in tabs, bookmarks, and history. The Favicon Generator turns one logo into the full set you need: PNG icons in 6 sizes, plus a real multi size favicon.ico file.
Upload a logo, check it at 16, 32, and 48 pixels actual size, then download the sizes you need. Everything runs in your browser, so your logo never leaves your device.
How to Use This Tool
- Upload a logo: drop an image into the box, or click it to browse. A square logo of 512 pixels or more works best.
- Check the previews: look at the 16, 32, and 48 pixel previews at actual size, plus the large preview.
- Download PNGs: click a PNG size button for 16, 32, 48, 180, 192, or 512 pixels.
- Download the ICO: click Download favicon.ico for the multi size file browsers look for by default.
About the ICO File
The favicon.ico file built here is a real ICO container. It starts with an ICO header, then one directory entry per size, then the PNG image data for 16, 32, and 48 pixels. It is not a PNG file with a renamed extension. Because the payloads are PNG images, transparency is kept, and modern browsers read this form fine.
Why Use This Tool
- Real ICO, not a rename: the container, directory entries, sizes, and offsets are built in code.
- Actual size previews: judge readability at true tab sizes before you download.
- Transparency kept: PNG output and PNG payloads inside the ICO both keep transparency.
- Private by design: your image never leaves your device.
