I personally used PDF Candy to turn a technical manual I downloaded for work, which made it much easier to read on my tablet during meetings.
I also tried converting a set of old software guides I had saved in CHM format. Having them as PDFs meant I could annotate, highlight, and share them with colleagues without worrying about compatibility issues. I appreciated being able to pull data directly from my Google Drive.
What is a CHM file
A CHM extension is a specialized digital format primarily employed for distributing software documentation and help content.
Microsoft created CHM files, which are a practical means of combining and delivering help resources offline. Images, other relevant sources, and a compilation of HTMLs make up this extension.
An index, a search function, and a table of contents are standard components of the CHM format. These offer an orderly and structured method of presenting data; they are especially helpful for software manuals and guides.
For official guidance on archiving, you can also refer to National Archives’ resources on managing digital information.

FAQ about turning CHM into PDF
Can I maintain the table of contents (TOC) and indexing?
This can be difficult. CHM's interactivity and hierarchical structure do not directly translate to a static PDF format. However, with advanced conversion techniques, the TOC can be preserved as bookmarks. Keep in mind that dynamic links may be lost.
Does CHM encryption affect the conversion?
If it is password-protected, you must first decrypt the content. Without entering the code, the inside of the CHM will be inaccessible.
