Background music

In addition to visual content, OpenComic can play background music from the comic folder:

Place audio files in the same folder as your comic pages, and OpenComic will automatically detect and offer to play them as background music while reading.

​
Format detection

OpenComic automatically detects file formats based on:
  1. File extension
  2. File header analysis (magic numbers)
  3. Content inspection when needed
This intelligent detection ensures that files are handled correctly even if they have incorrect or missing extensions.

​
Nested archives

OpenComic supports reading comics inside nested compressed files. For example, you can read:
  • A CBZ file inside a ZIP archive
  • A folder of images inside a RAR file within a 7Z archive
The application automatically extracts nested archives as needed, making your reading experience seamless.
