What is JPG?
JPG (also written JPEG) is the most widely used photo format in the world. It uses lossy compression tuned for natural photographs, shrinking files dramatically while keeping images that look great to the human eye. Every camera, phone, browser, and photo app supports JPG, which makes it the safest choice for sharing photographs, sending email attachments, and uploading pictures online.
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 JPG to ICO?
Converting JPG 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. JPG is not always the most convenient format to work with. Whatever your reason, Snap2Format handles the JPG to ICO conversion in seconds — right in your browser, with no quality loss you would notice and no software to install.
