Convert PNG to ICO
Create a multi-size ICO favicon from a PNG.
Frequently Asked Questions
What sizes are included in the ICO file?
Every ICO contains four sizes: 16×16, 32×32, 48×48 and 64×64 pixels, so it works as a favicon in browsers, Windows and macOS. Transparency is preserved.
Is my favicon uploaded anywhere?
No. Your image is converted locally in your browser and never leaves your device. That makes it ideal for brand assets like favicons.
Can I convert multiple images at once?
Yes — use Image Factory to build a batch pipeline: convert, compress, crop and resize many images in one flow, entirely on your device.
