A4A (Asyncio 4chan Archiver or Asyncio 4 Archiving, depending on how much the reader cares about the 4chan API ToS) is a Python script to download all images/videos of a 4chan thread.

Usage

usage: inb4404.py [-h] [-f] [-p PATH] [-a FILE] [--connections N]
                  [--retries N]
                  thread [thread ...]

A4A is a Python script to download all files from 4chan(nel) threads.

positional arguments:
  thread                url of the thread

optional arguments:
  -h, --help            show this help message and exit
  -f, --filenames       use original filenames instead of UNIX timestamps
  -p, --path PATH       set output directory (def: <script location>/downloads)
  -a, --archive FILE    keep track of downloaded files by logging MD5 hashes
  --connections N       number of connections to use (def: 10)
  --retries N           how often to retry a thread if errors occur (def: 5)
                          N<0 to retry indefinitely (not recommended)

Requirements

• Python >= 3.7
• aiohttp

Paths

The final output directory is assembled according to the following structure

<base path>/<board>/<directory name>

<base path> and <directory name> are variable components, which can be changed by the user.

• <base path> can be changed with -p/--path (defaults to <path to inb4404.py>/downloads)
• <directory name> can be set by adding the desired name to the thread link separated by another "/" (defaults to thread number)

For example:

https://boards.4channel.org/abc/thread/12345678        -> <path to inb4404.py>/downloads/abc/12345678
https://boards.4channel.org/abc/thread/12345678/my_dir -> <path to inb4404.py>/downloads/abc/my_dir
