Favicon Generator
Upload a logo and generate all favicon sizes + .ico in seconds.
About this tool
Upload any image or logo and instantly generate a complete, production-ready favicon package. The tool uses multi-step downsampling (iterative halving) for sharp, accurate icons even at 16x16. It automatically detects transparency, lets you set a background color and padding, and outputs a multi-layer .ico, Apple Touch Icon, Windows tile, Android/PWA icons, site.webmanifest, browserconfig.xml and the HTML you need. Everything runs in your browser — nothing is uploaded.
How to use the Favicon Generator
- 1Click the upload area or drag and drop your logo image (PNG, JPG, SVG or WebP — square, at least 512x512 px recommended).
- 2Adjust customization: optionally set padding or change the background color (auto-enabled for transparent images to protect Apple and Windows tiles).
- 3Preview your favicon in the browser tab mockup and at every standard size, then download individual PNGs, the .ico, or everything as a ZIP.
Frequently asked questions
What image size should I upload?
A square image at least 512x512 pixels is recommended. If your image is smaller, a warning will appear — larger icons may look blurry. Non-square images are centered automatically.
What is a favicon.ico file?
An .ico file is a container format that bundles multiple icon sizes (16x16, 32x32, 48x48) into one file. It is the legacy standard still expected by some browsers and operating systems.
Is my image uploaded to a server?
No. All processing — resizing, ICO generation, ZIP packaging — happens locally in your browser via the Canvas API. Nothing is uploaded.
What files are included in the ZIP?
favicon.ico (multi-layer), PNGs at 16, 32, 48, 150 (Windows tile), 180 (Apple Touch Icon), 192 and 512 (Android/PWA), plus site.webmanifest, browserconfig.xml, and a how-to-use guide.
Why does the background color turn on automatically for transparent images?
iOS renders transparent areas as a solid black box on home screens, and Windows tiles show the system tile color through them. The tool detects transparency and automatically enables a clean background so your icons look great across all devices.
Why is the background color disabled when padding is 0%?
When an opaque (non-transparent) image has 0% padding, it fills the entire square canvas edge-to-edge. Because there are no margins or transparent pixels, any background color chosen would be completely covered and invisible behind the image. Setting padding to 1% or higher (>= 1%) creates space around the logo, revealing the background and enabling the color controls. (For transparent images, background color is always available regardless of padding.)
What happens if I turn off background color for a transparent logo?
Standard browser tab favicons (16x16, 32x32, 48x48) and PWA icons will keep their transparent backgrounds. However, to prevent broken display on Apple devices where iOS forces transparency to render pitch black, the Apple Touch Icon (180x180) and Windows tile (150x150) automatically fall back to a white background.
