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.
WEBP is a modern image format developed by Google, designed to provide superior compression and quality compared to traditional formats like JPEG and PNG. It is widely supported by web browsers, image editing tools like Photoshop and GIMP, and libraries such as libwebp for encoding and decoding. The format supports both lossy and lossless compression, transparency, animation, and metadata, making it versatile for web and mobile applications.
You can also convert CHM into many other file formats. Please see the complete list below.
