CHM (Compiled HTML Help) is a Microsoft-proprietary format introduced with Windows 98 as a help documentation system. A .chm file bundles multiple HTML pages, images, and a table of contents into a single compressed binary. It was widely used for software documentation, tutorials, and technical manuals throughout the 2000s. Although largely replaced by online documentation and PDF, millions of CHM files still circulate as offline technical references. Converting CHM to modern ebook formats makes this legacy content accessible on e-readers and mobile devices.
Converting CHM to PML processes the CHM source through Calibre's content pipeline to produce a well-formed PML output. Our conversion service uses Calibre, the gold-standard open-source ebook management tool, ensuring that text encoding, chapter markers, and embedded assets are faithfully transferred. The converted PML file retains the original book's content and structure for use on compatible devices.
PML (Palm Markup Language) is the format used by the eReader application on Palm and Windows Mobile devices. PML files are lightweight and well-suited for low-powered hardware. Converting to PML is primarily relevant for users with legacy Palm devices or eReader installations. The format supports basic text styling and is easily editable as a text-based markup. Most content archived from the Palm era uses PML as its source format.
CHM files may contain multiple HTML pages that form a book-like structure. Calibre will attempt to reconstruct a table of contents from the CHM's navigation index. Verify the chapter order in the output PML matches the original CHM navigation. PML is a legacy format primarily for specific historical hardware. Verify your target device supports PML before converting. For modern devices, EPUB or MOBI are better choices. Our conversion engine processes CHM to PML entirely in the cloud — no software installation needed. Files are deleted from our servers within 24 hours of upload.
