Questions
What sizes do I actually need?
A favicon.ico containing 16, 32 and 48 pixel versions covers browser tabs, bookmarks and Windows shortcuts. Add a 180 pixel PNG for iOS home screens. Modern browsers will also use an SVG favicon if you offer one, which stays sharp at any size.
Why does my favicon look like mush?
Because 16 by 16 pixels is about ten usable pixels once the padding is accounted for, and most logos have far more detail than that. Simplify: one shape, high contrast, no text. A detailed logo shrunk to 16 pixels reads as a grey smudge.
Are my images uploaded anywhere?
No. Favicon Generator runs entirely inside your browser using the Canvas API. The file is read from your device, processed on your device, and the result is handed straight back to you. It never travels to a server, so there is nothing for us to store, log or leak.
Is it free, and is there a limit?
It is free with no account and no watermark. Because the work happens on your own hardware there is no per-image cost to us, so there is no quota. The only real limit is your device's memory: images beyond roughly 40 megapixels are refused rather than crashing the tab.
Does it work on a phone?
Yes. The tools work in any current mobile browser, and the result downloads to your camera roll or Files app like any other download. Very large images are slower on a phone than on a laptop because the processing is genuinely happening on the device.
