Kindle devices do not open CHM help files directly, so converting one to AZW3 makes its contents usable as a Kindle ebook. The conversion extracts the help pages and packages them in a format Kindle readers support.
What the CHM format is
CHM (Compiled HTML Help) is a Microsoft format that packages HTML pages, images, a table of contents, and indexes into a single file. It is commonly used for Windows software manuals and help systems; Microsoft HTML Help Workshop and other help-authoring tools can create CHM files.
What the AZW3 format is
AZW3, also called Kindle Format 8 (KF8), is an ebook format for Kindle devices. It supports reflowable text, images, tables of contents, and more advanced HTML and CSS formatting than older Kindle formats, making it suitable for reading CHM documentation on a Kindle.

Quality and compatibility
CHM is a collection of linked help pages, not a conventional ebook, so conversion may change page layout, navigation, or formatting. Check the converted table of contents and links; complex tables and page-specific styling may not render exactly as they do in a CHM viewer. If the CHM contains sensitive material, use desktop conversion rather than uploading it.
