Convert CHM to PDF

Understanding CHM and PDF file formats

CHM (Compiled HTML Help) is a proprietary format developed by Microsoft for online help documentation. It bundles HTML pages, images, and navigation into a single compressed file, commonly used for software manuals and eBooks. PDF (Portable Document Format), created by Adobe, is a widely used format for sharing documents with consistent formatting across platforms. PDFs are ideal for printing, archiving, and sharing documents securely.
