Read CHM+ is the complete solution for Mac users who need to read and archive Windows Compiled HTML Help files. Beyond comfortable, full-featured reading, its built-in PDF export converts entire CHM files into professional-quality PDFs — translating the original table of contents into interactive PDF bookmarks and preserving all internal and external hyperlinks as PDF-compatible annotations. Everything runs entirely offline on your Mac.

Key Features
CHM to PDF Export
Convert CHM files into professional-quality PDF documents — translating the original table of contents into interactive PDF bookmarks and preserving all internal and external topic hyperlinks as PDF-compatible annotations.
Custom PDF Page Setup
Customise the output PDF page size, margin, and orientation before exporting — giving you control over how the converted document looks in print or on screen.
Three-Panel Navigation Sidebar
Navigate CHM files using a sidebar with three dedicated panels — Table of Contents, Index list, and Search results — for instant access to any section of the document.
Full-Text Search
Search across the entire CHM file or its index, with additional support for finding text within the currently viewed page — results highlighted directly on screen.
Bookmark Management
Add and manage bookmarks for future reading — organised by file, grouped by tags, and surfaced in a recent bookmarks list for fast access across large technical libraries.
Reading History Navigation
Navigate your reading session with Home, Back, and Forward controls — maintaining a full reading history so you can retrace your path through complex documentation.
Vast Text Encoding Support
Supports a wide range of text encodings for accurate character display — essential for CHM files from non-English sources that may otherwise show garbled text.
Standalone & Fully Private
No internet connection or external dependency required. All reading and PDF export runs natively on your Mac — your technical documentation never leaves your device.
