Favicon generator

Create PNG icons, an ICO file and a ZIP package locally from one image.

Up to 10 MiB per image; 30 MiB and 24 megapixels per batch. Work surfaces: 4 megapixels. Job deadline: 15 seconds. Outputs: 24 MiB. Processing stays in your browser. Without OffscreenCanvas, native drawing can briefly delay the interface. After cancellation, retry once pending native decoding or encoding finishes.

Transparent padding preserves proportions. PNG sizes: 16, 32, 48, 180, 192, 256, 512. ICO uses PNG-backed 32, 48 and 256 images for modern clients.

Still JPEG, PNG or WebP. Select files in order; each selection replaces the current list.

How to use

Select an image and generate icons. Inspect the 512-pixel preview, then download individual sizes, ICO or ZIP.

Try an example

One package includes PNGs at 16, 32, 48, 180, 192, 256 and 512 pixels, and an ICO containing 32, 48 and 256-pixel images.

Support & limits

Images fit a square with transparent padding and no cropping. ICO embeds PNG images for modern browsers and clients; legacy compatibility is not guaranteed. Review small-size clarity. The package does not modify your website automatically.

Common questions
