We sometimes receive documents in CHM format, which is the help file developed by Microsoft, consisting of a set of HTML files with texts, images and links, it is widely used for software documentation, courses, etc.

If you're working on a PC, the files are easy to read, but if you need to open CHM files on Mac, you may need to get a CHM reader or convert CHM to a popular format such as PDF format. Here, in this article, we will introduce 3 ways for you to convert CHM to PDF on Mac

Method 1. Use Dedicated CHM to PDF Converter Software for Mac

After downloading and testing several CHM to PDF converters on the Internet, I finally pick Cisdem PDFMaster as the best Mac CHM to PDF converter, for the reason that it gives very good results and supports converting files in batch. 

PDFMaster is a simple yet useful app which can convert CHM files to PDF format with high-quality and fast speed. But it is more than a CHM to PDF converter, it is a PDF toolkits with 8 modules supporting most of PDF tasks.

Adobe Acrobat supports creating PDF from scratch, also from existing resources saved in Word, PowerPoint, Excel, Image or others, it is reasonable that you just wonder if we can convert CHM to PDF on Mac using Adobe Acrobat.

  • Text, RTF
  • PSD, EPS, AI
  • HTML
  • DWG

Final Words

As the popularity of CHM files goes undermined, there are less and less tools designed to work for this format, even Microsoft stops adding features to CHM. If you have a informative CHM file, save it as PDF to have an easier access to, using PDFMaster or an online free CHM to PDF converter.
