CHM eBook Format CHM Converter
Microsoft Compiled HTML Help files use the extension .chm. They contain compressed help documentation in an HTML format that can open in web browsers and Microsoft HTML Help Executable. Like other HTML files, CHM files can contain images as well as text and links. Previously, CHM files were quite common as download links on websites; however, they could be vulnerable to hackers. Microsoft has also confirmed that it will not be adding any extra features to Help.
For security and accessibility, most websites now have help sections using search functions or dropdown FAQs rather than needing additional downloads. While you can open CHM files with an internet browser, most companies advise caution unless the source is trusted. However, Microsoft programs still use the format and you can open a CHM file on a Windows computer by double-clicking on the file. The CHM format is also sometimes used now for ebook files, and you can open this type of CHM file with Calibre’s ereader software.
EPUB eBook Format EPUB Converter
EPUB is the standard open-source format for ebooks. EPUB is short for ‘electronic publication’. The format was developed in the mid-late 2000s by the International Digital Publishing Forum and is an alternative to formats like AZW, developed for the Kindle. EPUB files can be viewed on a wide range of e-readers and digital reading apps, including NOOK, Apple Books, Okular and Calibre. Amazon announced in 2022 that new Kindle models would also support EPUB files.
The EPUB standard is now maintained by a World Wide Web Consortium (W3C) working group. The EPUB format comprises three open standards – one defining content markup, one describing the ebook structure, and one packaging all the files into a compressed format. EPUB files normally include an index page for navigation, and accessibility features to adjust text size or allow for text-to-speech. EPUB also has the potential to include interactivity, accessible image, video, or audio elements.
