CHM Reader — Open, Search & Export Windows Help Files
Open Windows Help (.chm) files on your iPhone and iPad — instantly, natively, and beautifully. CHM files are the standard documentation format for software manuals, technical guides, offline help systems, and e-books. CHM Reader brings full, faithful support to iOS so you can access all your documentation anywhere — even without an internet connection.
READ ANY CHM FILE
Import CHM files from the Files app, iCloud Drive, Dropbox, email attachments, or any other app on your device. CHM Reader parses the full table of contents, chapters, and embedded HTML pages — just like the original Windows Help viewer.
SEARCH & NAVIGATE
Full-text search across every chapter and topic inside your CHM file. Jump directly to any section in one tap. Browse the table of contents with a familiar, collapsible tree view.
EXPORT TO PDF
Convert any CHM page or the entire document to a shareable PDF in one tap. Perfect for saving offline documentation or sending it to colleagues.
BEAUTIFUL READING EXPERIENCE
Read in light or dark mode with customizable accent colors. Clean, distraction-free rendering faithfully preserves the original HTML formatting of every page.
