Fun Fact
A JPG saved at 60% quality is often visually indistinguishable from 100% quality to the human eye, yet can be less than half the file size.
Historical Context
The JPEG format was introduced in the early 1990s to solve a critical problem of the early internet: slow data transfer. Adjustable quality compression became its defining feature, enabling images to be shared efficiently long before broadband existed. Tools like this continue that legacy by giving users precise control over image performance.
