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.
The PPTM file format is a macro-enabled presentation format used in Microsoft PowerPoint, allowing users to embed and execute macros within the presentation. It is primarily supported by Microsoft PowerPoint and other compatible office suites like LibreOffice and Apache OpenOffice, enabling advanced automation and interactivity.
