Chan-DL

4chan thread downloader based on PySide6 (QT)

Why does this exist?

Because there's no way to download the entire thread in HTML with both the thumbnails and full resolution images or videos for offline viewing.

Roadmap

• 🚧 Modular system: So the end user will be able to write their own classes based on the API
• 🚧 Other Imageboards: Add support for other imageboards

Requirements

• Windows 10 or Linux

Installation

Windows | Linux

1. Download the latest release for your system from the Releases page.
2. Extract the archive and run the chan-dl executable.
3. After downloading a thread, use python -m http.server in it's root (or other http server) to browse the downloaded content locally.
