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.
