Converter from chm to pdf. How to convert CHM file to PDF file

This problem can be solved by converting CHM files into a portable and widely used PDF format. This will make it easy to distribute CHM files ( technical documentation, e-books, manuals, etc.) among users who prefer to read texts on PDAs or smartphones, as well as among users of Macintosh computers or Linux OS.

The CHM file format and its associated .chm filename extension, is a proprietary file format developed by Microsoft. Its full name is compiled HTML Help. CHM was released to the public in 1997 as a bundle with Microsoft Windows 98 and was primarily designed to facilitate documentation on the Windows platform, particularly help files for software applications that run on the Microsoft Windows platform. Essentially, a CHM file is a collection of HTML files packed as a single compressed file. Though the format is proprietary, it was successfully reverse engineered by the late 90"s to early 2000s allowing the development of open source readers that are capable of opening files with the .chm extension. The format was succeeded by the LIT format.

pdf Portable Document Format File

The .pdf file format extension was developed by Adobe systems in 1993 as a means of presenting documents in a consistent manner across different platforms, hardware, operating systems, and applications. The format was not released as an open source document format until 2008, though minimal proprietary technologies still controlled by Adobe Systems exist in the format. Every .pdf document carries with it the necessary meta information required to properly reconstruct the text, fonts, and graphics used to produce the document. This ensures that documents will be viewed in exactly the same way the author intended regardless of the device used to open the document. From conception to date, Adobe Systems has continued to support the format adding features with every iteration of the standard including hardened algorithms for document encryption and privacy. Today, many freely available readers exist allowing you to open and view .pdf documents and create or convert other file formats such as .jpeg and .doc into .pdf documents.

CHM Document File Format

CHM (Microsoft Compiled HTML Help) files are proprietary files Microsoft. They are HTML pages used for online formatting and indexing navigation tools. CHM files are compressed and hosted using binary files, and are often used to host application documentation.

In addition, on HTML pages you can place tags, images, text, hyperlinks, etc., which allows you to improve the quality of help files. Thanks to reverse engineering capabilities, CHM files are supported by many various programs to view documents. The LIT file extension is a modified version of CHM files (it's worth noting that the CHM format is also used e-books).
