## Project history and usage

Kepubify is a standalone EPUB-to-Kobo-EPUB conversion tool for Kobo eReaders, with companion utilities for cover generation and series metadata.

### Project history

The pgaskin/kepubify repository was created on GitHub on 2017-07-27. Its README describes a fast converter that also works as a Go library and web app, handles malformed HTML/XHTML, and includes covergen and seriesmeta companion tools.

The project website presents Kepubify as a command-line converter for Kobo's enhanced KEPUB format, with downloads, documentation, and a browser-based converter.

### Adoption history

Kepubify found a niche among Kobo users who prefer command-line conversion or batch workflows instead of GUI ebook-management software. On 2026-07-01, GitHub API metadata reported 878 stars and 58 forks, and Homebrew metadata listed v4.0.4 with 35 installs in the previous 30 days.

### How it is used

Users run kepubify to convert EPUB files or directories into Kobo-compatible KEPUB files. The included covergen utility pre-generates cover images for faster library browsing, while seriesmeta updates Kobo database metadata from EPUB3 or Calibre series data.

### Why package nerds care

Kepubify is package-nerd bait because it is a small, fast, single-purpose replacement for heavier ebook-conversion workflows. It is also a good example of packaging device-specific media behavior as a cross-platform CLI.
