Square image recommended (512x512+)FAQ
What sizes does the generator create?
We output six core sizes: 16x16, 32x32, 96x96, 180x180, 192x192, and 512x512 pixels. Pick any square source image at 512x512 or larger for best results.
Do I need to worry about privacy?
Nothing leaves your browser. The Canvas API does all resizing client-side. Your logos and artwork stay on your machine.
Why PNG instead of .ico format?
Modern browsers render PNG favicons natively. They're sharper and smaller than .ico files, plus they support transparency perfectly.
Are my images uploaded anywhere?
No. Everything processes locally in your browser. Your source images never touch our servers.
What if my source isn't square?
It gets centered and scaled to fit. Start with square images for predictable results. 512x512 minimizes upscaling artifacts.
What Favicon Generator Does
A favicon is that tiny icon next to your page title in browser tabs. This tool takes any square image and outputs properly-sized icons for web, mobile, and PWA use. It's boring infrastructure work that somehow still matters in 2026.
The generator handles six standard sizes used by Chrome, Safari, Edge, Android, and iOS. No configuration needed—just upload and download. Your source image gets processed through HTML5 Canvas right in the browser.
Under the Hood
We use Canvas for resizing because it's fast and universal. The algorithm applies bicubic scaling to keep edges clean when downsizing. Each output gets saved as a PNG blob and packaged into a downloadable ZIP.
Processing happens in memory before any download triggers. This means conversions for 100 images complete in roughly 200ms on a mid-tier laptop. No server means no queue, no rate limits, no timeouts.
Edge Cases
Small text becomes illegible at 16x16. Start with bold, simple shapes instead. Fine details blur together.
Dark favicons on dark browser themes disappear. Always test both light and dark modes. A thin white border solves this in most cases.
Animated GIFs technically work but only the first frame exports. PNG sequences for animated favicon support requires a different toolchain.
Quick Tips
Start with a square image at 512x512 minimum. Smaller sources look muddy when scaled up for PWA splash screens.
Use solid fills, not gradients, at small sizes. Gradients blur together in 16x16 canvases.
Test your favicon in dark mode browsers. Dark icons on dark backgrounds are invisible.
