In this guide, we show you how to convert data between the
OpenImageand
COCOformats for free. You can use your converted data to train
models and other models that support the
COCO format.
Roboflow is a universal conversion tool for computer vision annotation formats. The Public plan is the best way for those exploring personal projects, class assignments, and other experiments to try Roboflow. To convert your dataset, start by creating a free workspace on the Public plan.
Once your account has been created, click Create New Project.
Next, click "Generate New Version" to generate a new version of your dataset:

Here are some compatible models:
Yes! It is free to convert
OpenImages CSV
data into the
COCO JSON
format on the Roboflow platform.
If you have between a few and a few thousand images, converting data between these formats will be quick. But, the time it takes to convert between data formats increases with the more images you have.
