Upload your logo or icon and download all standard favicon sizes as PNG. Includes Apple Touch Icon and PWA icons. Nothing leaves your device.
Generate favicon PNG files at 16×16, 32×32, 48×48, 180×180, 192×192, and 512×512 pixels from any source image, all resized in the browser using the Canvas API, with no upload. Download individual sizes or a ZIP archive ready to drop into your project.
Covering all six sizes ensures compatibility with classic browser tabs (16/32/48 px), Apple Touch Icons (180 px), Android home-screen shortcuts (192 px), and PWA splash screens (512 px).
