How To Convert YOLOv8 PyTorch TXT to YOLOv4 PyTorch TXT
In this guide, we show you how to convert data between the YOLOv8 and YOLOv4 Pytorch formats for free. You can use your converted data to train YOLOv4 PyTorch models and other models that support the YOLOv4 Pytorch format.

YOLOv8 PyTorch TXT
A modified version of YOLO Darknet annotations that adds a YAML file for model config.
Below, learn the structure of YOLOv8 PyTorch TXT.
Each image has one txt file with a single line for each bounding box. The format of each row is
class_id center_x center_y width height
where fields are space delimited, and the coordinates are normalized from zero to one.
Note: To convert to normalized xywh from pixel values, divide x (and width) by the image's width and divide y (and height) by the image's height.
