What is a JPEG file?
JPEG is one of the most widely used image formats in the world. The name comes from the Joint Photographic Experts Group, which developed the standard in the early 1990s. JPEG files use lossy compression to reduce file size while maintaining acceptable image quality.
They are ideal for photos and web use but not for images that need frequent editing or high precision, as repeated saves degrade quality.
How to open JPEG files
JPEG files are universally supported. You can open them on any device — computer, tablet, or phone — with built-in apps or web browsers. Most photo editors also support JPEG natively.
If you want to convert JPEG to another format or resize it, AnyConv offers a fast and easy solution directly online.
