CopyManga Downloader is a free, open-source application designed for downloading manga from the CopyManga platform. It provides a graphical interface for searching titles, browsing chapters, and managing downloads. The software uses multithreaded downloading to retrieve manga images efficiently. Users can select individual chapters or download multiple chapters in a single operation. It also supports account login for accessing personal manga favorites and organizing selections. Downloaded manga can be exported to CBZ and PDF formats for reading in compatible applications. The project also supports downloading certain titles that have been removed from the platform and is designed to avoid the standard API request limit. Built with Tauri, Rust, and Vue, it offers a convenient alternative to manual manga downloading.
