Check our videoThe CHM file format was developed by Microsoft for storing and displaying online help documentation, combining multiple HTML pages into a single compressed file. It is commonly opened using Microsoft's HTML Help Viewer, but third-party tools like 7-Zip or SumatraPDF can also extract or view CHM files. The format supports a hierarchical table of contents, full-text search, and embedded multimedia, making it a versatile solution for organizing and accessing help content efficiently.
JPEG 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.
You can also convert CHM into many other file formats. Please see the complete list below.
