Check our videoJPEG is a widely used lossy compression format for digital images, balancing file size reduction with acceptable image quality. It is supported by most image editing software like Adobe Photoshop, GIMP, and web browsers, making it ideal for web use and digital photography. The format uses discrete cosine transform (DCT) for compression, supports progressive loading, and allows adjustable compression levels, though it sacrifices some detail due to its lossy nature.
XLSX is a widely used file format for spreadsheets, developed by Microsoft as part of the Office Open XML standard, succeeding the older XLS format. It is supported by Microsoft Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications, ensuring cross-platform compatibility. The format is based on XML and stored in a compressed ZIP container, enabling features like advanced formulas, charts, conditional formatting, and support for large datasets while maintaining smaller file sizes compared to its predecessor.
You can also convert JPEG into many other file formats. Please see the complete list below.
