• Native Performance: Runs natively on macOS with excellent performance and seamless integration with the system.

2. Powerful Built-in Search

• Diverse Output Formats: Converts CHM content into multiple commonly used formats with high quality:
  • PDF: Generate documents ideal for printing, archiving, and cross-platform distribution.

  • HTML: Extract as original web files for integration into websites or further development.
• Resource Extraction: Extracts all embedded resources (images, stylesheets, etc.) from CHM files with one click.

4. Broad Compatibility

• Format Support: Handles CHM files of various versions and encodings—whether old software help files, modern technical documents, or CHM e-books—opening them reliably.
