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.

PDF Document Format

PDF Converter

PDF stands for ‘Portable Document Format’ file. It was developed by Adobe so people could share documents regardless of which device, operating system, or software they were using, while preserving the content and formatting. The format has evolved to allow for editing and interactive elements like electronic signatures or buttons. The PDF format is now a standard open format that isn’t just available under Adobe Acrobat. It is maintained by the International Organisation for Standardization (ISO).

PDF files aren’t typically created from scratch, but are usually converted, saved or ‘printed’ from other documents or images before sharing, publishing online or storing. They can be viewed on almost all devices. Creating a PDF can involve compressing a file, making it take up less storage space. You would typically create a PDF if you wanted to ensure document fidelity, to make it more secure, or to create a copy for storage.
