FAQ
How do I make a favicon for free?
Upload a square image and this page redraws it at 16, 32, 48, 180, 192 and 512 pixels using your browser's canvas, and gives you a starter web manifest — all on your device with no upload.
Is my image uploaded anywhere?
No. The image is read and resized entirely in your browser and nothing is transmitted or stored, which you can verify by turning off your Wi-Fi.
What sizes do I actually need?
16 and 32 px for browser tabs, 180 px for Apple touch icons, and 192 and 512 px for the web manifest and installable apps. This tool produces all of them.
Should my source image be square?
Yes. A square source at 512 px or larger gives the cleanest results at every size; non-square images are stretched to fit.
Limits
Resizes a raster copy at each size; it does not generate a multi-resolution .ico file or hand-tune tiny sizes.
