JPG (Joint Photographic Experts Group), is a universal file format that utilizes an algorithm to compress photographs and graphics. The considerable compression that JPG offers is the reason for its wide use. As such, the relatively small size of JPG files makes them excellent for transporting over the Internet and using on websites. You can use our compress JPEG tool to reduce the file size by up to 80%!

If you need even better compression, you can convert JPG to WebP, which is a newer and more compressible file format.

Almost all image-viewer programs and applications recognize and can open JPG files. Simply double-clicking the JPG file will usually result in its opening in your default image viewer, image editor, or web browser. To select a specific application to open the file, utilize right-click, and select "Open with" to make your selection.

JPG files open automatically on popular web browsers such as Chrome, Microsoft applications such as Microsoft Photos, and Mac OS applications such as Apple Preview. To resize JPEG images use our Image Resizer tool.
