JPEG
XLS files
JPEG (Joint Photographic Experts Group) is a widely used image format known for its lossy compression. JPEG files are suitable for photographs and images with smooth color gradients. They offer a good balance between image quality and file size.
XLS (Microsoft Excel spreadsheet) is an older file format used for storing spreadsheet data. Although largely replaced by XLSX, XLS files can still be opened and edited in Microsoft Excel. They contain tabular data with formulas, charts, and formatting.
