PNG to ICO Converter (Favicon Generator)

How to convert PNG to ICO
- 1Use a square PNG at 256×256 or larger for the sharpest result.
- 2Drop it onto the converter and choose ICO as the output.
- 3Download the .ico and place it at the root of your site as favicon.ico.
Things worth knowing
- Simple, high-contrast shapes read far better at 16×16 than detailed artwork does.
- Keep the background transparent so the icon sits cleanly on light and dark browser chrome.
PNG to ICO — frequently asked questions
What size should my PNG be?
Square and at least 256×256. Anything smaller gets upscaled and looks soft in the larger icon slots that Windows and bookmark managers use.
Where do I put the .ico file?
At the root of your website so it resolves at /favicon.ico. Browsers check that path automatically even without a <link> tag, though adding the tag is still good practice.
Are my files uploaded to a server?
No. AllConverter runs the whole conversion inside your browser tab using WebAssembly and the Canvas API. Your file never travels over the network, which you can confirm by watching your browser's Network tab while you convert.
