What is a PNG file?
PNG is a lossless image format. Every pixel is kept exactly, and it supports full transparency, which makes it the standard for logos, screenshots and graphics.
What is ICO?
ICO is the icon format used for website favicons and Windows app icons. One ICO file holds several sizes of the same icon (16, 32, 48, 64, 128 and 256 pixels).
Why convert PNG to ICO?
PNG is great for lossless quality and transparent backgrounds that work everywhere, but photos as PNG are much larger than the same photo as JPG or WebP. ICO is the better choice for favicons and desktop icons; keep in mind only useful as an icon.
Will I lose quality?
No. ICO is lossless, so every pixel that PNG gave us is kept exactly.
Private by design
Most online converters upload your file to their servers. This one doesn't: the converter itself is loaded into your browser and works offline from there, so your pictures never leave your phone or computer.
