Label Training Images and Export To Any Format

Designed For Ultra Fast Labeling

Every aspect of Roboflow Annotate was built to make labeling faster and easier. With keyboard shortcuts, intelligent defaults, and integrated label creation, you can annotate hundreds of images in minutes.
Edit Existing Labels
Roboflow supports the most popular annotation formats including JSON, XML, CSV, and TXT. This means you can edit existing annotations and even add new ones to your training images.
Label From Scratch
Once your images are uploaded to Roboflow, you can draw bounding boxes around the objects you want to detect and assign classes as you go.
Collaborative Labeling
Share your datasets with colleagues and everyone can help label. Annotations and classes stay in sync across multiple accounts.
No Software To Install
Roboflow Annotate works right within the browser, which means you can label on any operating system.

Cut labeling time in half with Label Assist

As part of Roboflow Pro, Label Assist lets you automatically annotate images using an existing model
Get a head start
Label Assist detects objects in your images and places bounding boxes around them. If an annotation is misaligned, it's easy to adjust its size and position.
Don't have a trained model?
Use public models like Microsoft COCO, which is free with the Starter Plan, and detect 80 common objects like cars, bikes, people, and more.
