About labelImg
HumanSignal/labelImg
LabelImg is now part of the Label Studio community. The popular image annotation tool created by Tzutalin is no longer actively being developed, but you can check out Label Studio, the open source data labeling tool for images, text, hypertext, audio, video and time-series data.
Built with PyQt for its graphical interface, LabelImg outputs bounding box annotations in multiple formats—PASCAL VOC (ImageNet standard), YOLO, and CreateML—enabling compatibility with diverse computer vision pipelines. The tool supports batch processing via directory loading, predefined class lists, and annotation visualization by loading existing label files alongside images, streamlining workflows for dataset preparation.
