AugLy is a data augmentations library that currently supports four modalities (audio, image, text & video) and over 100 augmentations. Each modality’s augmentations are contained within its own sub-library. These sub-libraries include both function-based and class-based transforms, composition operators, and have the option to provide metadata about the transform applied, including its intensity.

AugLy is a great library to utilize for augmenting your data in model training, or to evaluate the robustness gaps of your model! We designed AugLy to include many specific data augmentations that users perform in real life on internet platforms like Facebook's -- for example making an image into a meme, overlaying text/emojis on images/videos, reposting a screenshot from social media. While AugLy contains more generic data augmentations as well, it will be particularly useful to you if you're working on a problem like copy detection, hate speech detection, or copyright infringement where these "internet user" types of data augmentations are prelevant.


To see more examples of augmentations, open the Colab notebooks in the README for each modality! (e.g. image README & Colab)

The library is Python-based and requires at least Python 3.6, as we use dataclasses.

AugLy is a Python 3.6+ library. It can be installed with:

pip install augly

Or clone AugLy if you want to be able to run our unit tests, contribute a pull request, etc:

git clone [email protected]:facebookresearch/AugLy.git
[Optional, but recommended] conda create -n augly && conda activate augly && conda install pip
pip install -e AugLy/

NOTE: In some environments, pip doesn't install python-magic as expected. In that case, you will need to additionally run:

conda install -c conda-forge python-magic

Or if you aren't using conda:

sudo apt-get install python3-magic


To find documentation about each sub-library, please see the READMEs in the respective directories.


We provide various media assets to use with some of our augmentations. These assets include:

  1. Emojis (Twemoji) - Copyright 2020 Twitter, Inc and other contributors. Code licensed under the MIT License. Graphics licensed under CC-BY 4.0.
  2. Fonts (Noto fonts) - Noto is a trademark of Google Inc. Noto fonts are open source. All Noto fonts are published under the SIL Open Font License, Version 1.1.
  3. Screenshot Templates - Images created by a designer at Facebook specifically to use with AugLy. You can use these with the overlay_onto_screenshot augmentation in both the image and video libraries to make it look like your source image/video was screenshotted in a social media feed similar to Facebook or Instagram.
