Why convert PNG to ICO?
Windows app icons and favicons. The .ico format bundles multiple sizes (16, 32, 48, 64, 128, 256) into one file. Most operating systems pick the right size automatically.
What happens when you click convert
- The page reads your file using a JavaScript or WebAssembly decoder.
- It re-encodes the pixel data as a ICO file.
- One file in, one file back. Several files in, a ZIP back.
Nothing leaves your browser
The whole conversion happens inside this tab. The simplest proof: load the page, kill your internet, run a conversion. Most converters still work.
