What is PNG?
PNG (Portable Network Graphics) is a lossless raster image format built for the web. It preserves every pixel of the original image, supports full alpha transparency, and never introduces compression artifacts. PNG is the go-to choice for logos, icons, screenshots, charts, and any graphic with sharp edges or text where a transparent background and crisp detail matter most.
What is ICO?
ICO is the standard Windows icon and website favicon format. A single ICO file can hold several resolutions (16×16, 32×32, 48×48 and larger) so the operating system or browser can choose the right size automatically. ICO is essential for adding a favicon to a website or creating custom application and desktop icons.
Why Convert PNG to ICO?
Converting PNG to ICO is one of the most common image tasks, and there are several good reasons to do it. ICO is exactly what you need to add a favicon to your website or build a custom Windows icon. Because PNG photos can be large, converting helps whenever you need a smaller, more shareable file. Whatever your reason, Snap2Format handles the PNG to ICO conversion in seconds — right in your browser, with no quality loss you would notice and no software to install.
