Favicon Generator — PNG to .ico in One Click
Generate a favicon.ico with all sizes (16–256px) from one PNG or SVG logo. Instant preview, free, no upload, no signup. The classic favicon maker.
Every browser tab, bookmark list, and home-screen shortcut pulls from your favicon — and getting all the required sizes right by hand is tedious. Upload one square logo and this generator produces a proper multi-resolution .ico plus the standard PNG sizes for modern browsers.
The conversion runs in your browser: your logo is not uploaded to a favicon farm, and there is no watermark, account, or size limit.
100% in-browser · no upload · no signup · nothing you paste or drop here leaves your device

All image processing happens locally in your browser — your source image is never uploaded. The generated .ico file bundles every selected size as required by the format spec. Results depend on your browser's canvas implementation. Provided as-is for development use.
A favicon is a folder of icons — illustrated
An .ico is really a container: it bundles several PNG-style images, each with its own size, and a small directory table at the front. The OS picks the entry closest to where the icon will be drawn — 16px for the address bar, 32px for taskbar, 48px+ for desktop. Shipping multiple sizes avoids blurry upscaling everywhere the icon appears.
The DIR header lists each embedded image's size and offset. The browser/OS chooses the best match instead of stretching one bitmap. Standard set: 16, 32, 48, 64, 128, 256.
A site that will appear in Chrome, Windows taskbar and a mobile bookmark.
- 16 + 32:Browser tab and window icon — the standard minimum
- 48 + 64:Windows Explorer large view and quick-launch
- 128 + 256:High-DPI taskbar and pinch-zoom crispness
- Rule of thumb:More included sizes ≈ slightly bigger file, but sharp icons everywhere

Frequently asked questions
What sizes should a favicon.ico contain?
The classic multi-resolution .ico bundles 16×16 (browser tabs), 32×32 (taskbars and bookmarks), 48×48, and 256×256 (high-DPI and app shortcuts) in one file. Browsers pick the best size automatically, which is why one well-built .ico still beats a pile of separate PNGs for compatibility.
What image should I start from?
A square PNG or SVG of your logo at 256×256 or larger, with a transparent background, works best. The generator resizes down cleanly; starting large avoids the blurry edges you get from upscaling a tiny source image.
