- `Windows <https://github.com/mikf/gallery-dl/releases/download/v1.14.3/gallery-dl.exe>`__
- `Linux   <https://github.com/mikf/gallery-dl/releases/download/v1.14.3/gallery-dl.bin>`__

These executables include a Python 3.8 interpreter
and all required Python packages.


Snap
----

Linux users that are using a distro that is supported by Snapd_ can install *gallery-dl* from the Snap Store:

.. code:: bash

    $ snap install gallery-dl

Chocolatey
----------

Windows users that have Chocolatey_ installed can install *gallery-dl* from the Chocolatey Community Packages repository:

.. code:: powershell

    $ choco install gallery-dl


Usage
=====

To use *gallery-dl* simply call it with the URLs you wish to download images
from:

.. code:: bash

    $ gallery-dl [OPTION]... URL...

See also :code:`gallery-dl --help`.


Examples
--------

Download images; in this case from danbooru via tag search for 'bonocho':

.. code:: bash

    $ gallery-dl "https://danbooru.donmai.us/posts?tags=bonocho"


Get the direct URL of an image from a site that requires authentication:

.. code:: bash

    $ gallery-dl -g -u "<username>" -p "<password>" "https://seiga.nicovideo.jp/seiga/im3211703"


Filter manga chapters by language and chapter number:

.. code:: bash

    $ gallery-dl --chapter-filter "lang == 'fr' and 10 <= chapter < 20" "https://mangadex.org/title/2354/"


| Search a remote resource for URLs and download images from them:
| (URLs for which no extractor can be found will be silently ignored)

.. code:: bash

    $ gallery-dl "r:https://pastebin.com/raw/FLwrCYsT"


If a site's address is nonstandard for its extractor, you can prefix the URL with the 
extractor's name to force the use of a specific extractor:

.. code:: bash

    $ gallery-dl "tumblr:https://sometumblrblog.example"


Configuration
=============

Configuration files for *gallery-dl* use a JSON-based file format.

| For a (more or less) complete example with options set to their default values,
  see gallery-dl.conf_.
| For a configuration file example with more involved settings and options,
  see gallery-dl-example.conf_.
| A list of all available configuration options and their
  descriptions can be found in configuration.rst_.

*gallery-dl* searches for configuration files in the following places:

+--------------------------------------------+------------------------------------------+
| Linux                                      | Windows                                  |
+--------------------------------------------+------------------------------------------+
|* ``/etc/gallery-dl.conf``                  |* ``%APPDATA%\gallery-dl\config.json``    |
|* ``${HOME}/.config/gallery-dl/config.json``|* ``%USERPROFILE%\gallery-dl\config.json``|
|* ``${HOME}/.gallery-dl.conf``              |* ``%USERPROFILE%\gallery-dl.conf``       |
+--------------------------------------------+------------------------------------------+

(``%USERPROFILE%`` usually refers to the user's home directory,
i.e. ``C:\Users\<username>\``)

Values in later configuration files will override previous ones.

Command line options will override all related settings in the configuration file(s),
e.g. using ``--write-metadata`` will enable writing metadata using the default values
for all ``postprocessors.metadata.*`` settings, overriding any specific settings in
configuration files.


Authentication
==============

Username & Password
-------------------

Some extractors require you to provide valid login credentials in the form of
a username & password pair. This is necessary for
``pixiv``, ``nijie``, and ``seiga``
and optional for
``danbooru``, ``e621``, ``exhentai``, ``idolcomplex``, ``inkbunny``,
``instagram``, ``luscious``, ``sankaku``, ``subscribestar``, ``tsumino``,
and ``twitter``.

You can set the necessary information in your configuration file
(cf. gallery-dl.conf_)

.. code:: json

    {
        "extractor": {
            "pixiv": {
                "username": "<username>",
                "password": "<password>"
            }
        }
    }

or you can provide them directly via the
:code:`-u/--username` and :code:`-p/--password` or via the
:code:`-o/--option` command-line options

.. code:: bash

    $ gallery-dl -u <username> -p <password> URL
    $ gallery-dl -o username=<username> -o password=<password> URL

Cookies
-------

For sites where login with username & password is not possible due to
CAPTCHA or similar, or has not been implemented yet, you can use the
cookies from a browser login session and input them into *gallery-dl*.

This can be done via the
`cookies <https://github.com/mikf/gallery-dl/blob/master/docs/configuration.rst#extractorcookies>`__
option in your configuration file by specifying

- | the path to a Mozilla/Netscape format cookies.txt file exported by a browser addon
  | (e.g. `cookies.txt <https://chrome.google.com/webstore/detail/cookiestxt/njabckikapfpffapmjgojcnbfjonfjfg>`__ for Chrome,
    `Export Cookies <https://addons.mozilla.org/en-US/firefox/addon/export-cookies-txt/?src=search>`__ for Firefox)

- | a list of name-value pairs gathered from your browser's web developer tools
  | (in `Chrome <https://developers.google.com/web/tools/chrome-devtools/storage/cookies>`__,
     in `Firefox <https://developer.mozilla.org/en-US/docs/Tools/Storage_Inspector>`__)

For example:

.. code:: json

    {
        "extractor": {
            "instagram": {
                "cookies": "$HOME/path/to/cookies.txt"
            },
            "patreon": {
                "cookies": {
                    "session_id": "K1T57EKu19TR49C51CDjOJoXNQLF7VbdVOiBrC9ye0a"
                }
            }
        }
    }

You can also specify a cookies.txt file with
the :code:`--cookies` command-line option:

.. code:: bash

    $ gallery-dl --cookies "$HOME/path/to/cookies.txt" URL

OAuth
-----

*gallery-dl* supports user authentication via OAuth_ for
``deviantart``, ``flickr``, ``reddit``, ``smugmug`` and ``tumblr``.
This is entirely optional, but grants *gallery-dl* the ability
to issue requests on your account's behalf and enables it to access resources
which would otherwise be unavailable to a public user.

To link your account to *gallery-dl*, start by invoking it with
``oauth:<sitename>`` as an argument. For example:

.. code:: bash

    $ gallery-dl oauth:flickr

You will be sent to the site's authorization page and asked to grant read
access to *gallery-dl*. Authorize it and you will be shown one or more
"tokens", which should be added to your configuration file.
