What to Download
^^^^^^^^^^^^^^^^
`Instaloader Documentation <https://instaloader.readthedocs.io/basic-usage.html>`__
Instaloader does not only download media by-profile. More generally, you
may specify the following targets:
- ``profile``: Public profile, or private profile with ``--login``,
- ``"#hashtag"``: Posts with a certain **hashtag** (the quotes are
usually neccessary),
- ``:stories``: The currently-visible **stories** of your followees
(requires ``--login``),
- ``:feed``: Your **feed** (requires ``--login``),
- ``@profile``: All profiles that are followed by ``profile``, i.e. the
*followees* of ``profile`` (requires ``--login``).
Instaloader goes through all media matching the specified targets and
downloads the pictures and videos and their captions. You can specify
``--comments`` to also **download comments** of each post and
``--geotags`` to **download geotags** of each post and save them as
Google Maps link. For each profile you download, ``--stories``
instructs Instaloader to **download the user's stories**.
Filename Specification
^^^^^^^^^^^^^^^^^^^^^^
For each target, Instaloader creates a directory named after the target,
i.e. ``profile``, ``#hashtag``, ``:feed``, etc. and therein saves the
posts in files named after the post's timestamp.
``--dirname-pattern`` allows to configure the directory name of each
target. The default is ``--dirname-pattern={target}``. In the dirname
pattern, the token ``{target}`` is replaced by the target name, and
``{profile}`` is replaced by the owner of the post which is downloaded.
``--filename-pattern`` configures the path of the post's files relative
to the target directory. The default is ``--filename-pattern={date}``.
The tokens ``{target}`` and ``{profile}`` are replaced like in the
dirname pattern. Further, the tokens ``{date}`` and ``{shortcode}`` are
defined.
For example, encode the poster's profile name in the filenames with:
::
instaloader --filename-pattern={date}_{profile} "#hashtag"
The pattern string is formatted with Python's string formatter. This
gives additional flexibilty for pattern specification. For example,
`strftime-style formatting options <https://docs.python.org/3/library/datetime.html#strftime-and-strptime-behavior>`__
are supported for the post's
timestamp. The default for ``{date}`` is ``{date:%Y-%m-%d_%H-%M-%S}``.
Filter Posts
^^^^^^^^^^^^
The ``--only-if`` option allows to specify criterias that posts have to
meet to be downloaded. If not given, all posts are downloaded. It must
be a boolean Python expression where the variables ``likes``,
``comments``, ``viewer_has_liked``, ``is_video``, and many
more are defined.
A few examples:
To **download the pictures from your feed that you have liked**:
::
instaloader --login=your_username --only-if=viewer_has_liked :feed
Or you might only want to download **posts that either you liked or were
liked by many others**:
::
instaloader --login=your_username --only-if="likes>100 or viewer_has_liked" profile
Or you may **skip videos**:
::
instaloader --only-if="not is_video" target
Or you may filter by hashtags that occur in the Post's caption. For
example, to download posts of kittens that are cute: ::
instaloader --only-if="'cute' in caption_hashtags" "#kitten"
.. basic-usage-end
(For a more complete description of the ``-only-if`` option, refer to
the `Instaloader Documentation <https://instaloader.readthedocs.io/basic-usage.html#filter-posts>`__)
Advanced Options
----------------
.. cli-options-start
The following flags can be given to Instaloader to specify how profiles should
be downloaded.
To get a list of all flags, their abbreviations and their descriptions, you may
run ``instaloader --help``.
What to Download
^^^^^^^^^^^^^^^^
Specify a list of profiles or #hashtags. For each of these, Instaloader
creates a folder and downloads all posts along with the pictures's
captions and the current **profile picture**. If an already-downloaded profile
has been renamed, Instaloader automatically **finds it by its unique ID** and
renames the folder likewise.
Instead of a *profile* or a *#hashtag*, the special targets
``:feed`` (pictures from your feed) and
``:stories`` (stories of your followees) can be specified.
--profile-pic-only Only download profile picture.
--no-videos Do not download videos.
--geotags **Download geotags** when available. Geotags are stored as
a text file with the location's name and a Google Maps
link. This requires an additional request to the
Instagram server for each picture, which is why it is
disabled by default.
--no-geotags Do not store geotags, even if they can be obtained
without any additional request.
--comments Download and update comments for each post. This
requires an additional request to the Instagram server
for each post, which is why it is disabled by default.
--no-captions Do not store media captions, although no additional
request is needed to obtain them.
--stories Also **download stories** of each profile that is
downloaded. Requires ``--login``.
--stories-only Rather than downloading regular posts of each
specified profile, only download stories.
Requires ``--login``.
--only-if filter Expression that, if given, must evaluate to True for each post to
be downloaded. Must be a syntactically valid python
expression. Variables are evaluated to
``instaloader.Post`` attributes.
Example: ``--only-if=viewer_has_liked``.
When to Stop Downloading
^^^^^^^^^^^^^^^^^^^^^^^^
If none of these options are given, Instaloader goes through all pictures
matching the specified targets.
--fast-update For each target, stop when encountering the first
already-downloaded picture. This flag is recommended
when you use Instaloader to update your personal
Instagram archive.
--count COUNT Do not attempt to download more than COUNT posts.
Applies only to ``#hashtag``, ``:feed-all`` and ``:feed-liked``.
Login (Download Private Profiles)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Instaloader can **login to Instagram**. This allows downloading private
profiles. To login, pass the ``--login`` option. Your session cookie (not your
password!) will be saved to a local file to be reused next time you want
Instaloader to login.
--login YOUR-USERNAME Login name (profile name) for your Instagram account.
--sessionfile SESSIONFILE Path for loading and storing session key file.
Defaults to a path
within your temporary directory, encoding your local
username and your Instagram profile name.
--password YOUR-PASSWORD Password for your Instagram account. Without this
option, you'll be prompted for your password
interactively if there is not yet a valid session
file.
How to Download
^^^^^^^^^^^^^^^
--dirname-pattern DIRNAME_PATTERN
Name of directory where to store posts. ``{profile}``
is replaced by the profile name, ``{target}`` is replaced
by the target you specified, i.e. either ``:feed``,
``#hashtag`` or the profile name. Defaults to ``{target}``.
--filename-pattern FILENAME_PATTERN
Prefix of filenames. Posts are stored in the
directory whose pattern is given with ``--dirname-pattern``.
``{profile}`` is replaced by the profile name,
``{target}`` is replaced by the target you specified, i.e.
either ``:feed``, ``#hashtag`` or the profile name. Also, the
fields ``{date}`` and ``{shortcode}`` can be specified.
Defaults to ``{date:%Y-%m-%d_%H-%M-%S}``.
--user-agent USER_AGENT User Agent to use for HTTP requests. Per default,
Instaloader pretends being Chrome/51.
Miscellaneous Options
^^^^^^^^^^^^^^^^^^^^^
--quiet Disable user interaction, i.e. do not print messages
(except errors) and fail if login credentials are
needed but not given. This makes Instaloader
**suitable as a cron job**.
.. cli-options-end
Usage as Python module
----------------------
.. as-module-intro-start
You may also use parts of Instaloader as library to do other interesting
things.
For example, to get a list of all followees and a list of all followers of a profile, do
.. code:: python
import instaloader
# Get instance
loader = instaloader.Instaloader()
# Login
loader.interactive_login(USERNAME)
# Print followees
print(PROFILE + " follows these profiles:")
for f in loader.get_followees(PROFILE):
print("\t%s\t%s" % (f['username'], f['full_name']))
# Print followers
print("Followers of " + PROFILE + ":")
for f in loader.get_followers(PROFILE):
print("\t%s\t%s" % (f['username'], f['full_name']))
Then, you may download all pictures of all followees with
.. code:: python
for f in loader.get_followees(PROFILE):
loader.download_profile(f['username'])
You could also download your last 20 liked pics with
.. code:: python
loader.download_feed_posts(max_count=20, fast_update=True,
filter_func=lambda post: post.viewer_has_liked)
To download the last 20 pictures with hashtag #cat, do
.. code:: python
loader.download_hashtag('cat', max_count=20)
Generally, Instaloader provides methods to iterate over the Posts from
a certain source.
.. code:: python
for post in loader.get_hashtag_posts('cat'):
# post is an instance of instaloader.Post
loader.download_post(post, target='#cat')
Each Instagram profile has its own unique ID which stays unmodified even
if a user changes his/her username. To get said ID, given the profile's
name, you may call
.. code:: python
loader.get_id_by_username(PROFILE_NAME)
.. as-module-intro-end

To **download all pictures and videos of a profile**, as well as the
**profile picture**, do
.. (continuation of --only-if explanation)
::
instaloader profile [profile ...]
where ``profile`` is the name of a profile you want to download. Instead
of only one profile, you may also specify a list of profiles.
To later **update your local copy** of that profiles, you may run
::
instaloader --fast-update profile [profile ...]
If :option:`--fast-update` is given, Instaloader stops when arriving at the
first already-downloaded picture. When updating profiles, Instaloader
automatically **detects profile name changes** and renames the target directory
accordingly.
Instaloader can also be used to **download private profiles**. To do so,
invoke it with
::
instaloader --login=your_username profile [profile ...]
When logging in, Instaloader **stores the session cookies** in a file in your
temporary directory, which will be reused later the next time :option:`--login`
is given. So you can download private profiles **non-interactively** when you
already have a valid session cookie file.

``:feed``
Your **feed** (requires :option:`--login`),
