About ICO files

ICO is a special format used for icons on Windows computers and websites. It is the format you see as the small image in browser tabs and on the Windows desktop. ICO files can store multiple image sizes inside one file.

What ICO is good for: ICO files are the standard for Windows icons and browser favicons. They can include several different sizes of the same icon in a single file, which is useful for displaying the icon at different scales.

Where ICO falls short: ICO is only useful for icons. It is not meant for regular photos or graphics. The format is not widely supported outside of icon-related tools and Windows programs.

When to use ICO: If you need to extract the image from an ICO file, convert it to PNG, JPEG, or WebP. This lets you use the icon image in regular programs, websites, and design tools.

About WEBP files

WebP is a modern image format made by Google. It is designed to make images smaller without making them look worse. Websites use WebP to load pages faster and save on storage costs.

What WEBP is good for: WebP files are usually 25–35% smaller than JPEG files at the same quality. It supports transparent backgrounds like PNG. All major browsers support WebP today, making it a safe choice for websites.

Where WEBP falls short: Some older apps and programs cannot open WebP files. If you need to send an image to someone using older tools, JPEG or PNG might be a safer choice for compatibility.

When to use WEBP: Use WebP when you are uploading images to a website. Smaller files mean your pages load faster, which keeps visitors happy and helps your site perform better.
