Step 1

Open the Spyder IDE (integrated development environment).

Step 2

Import the OpenCV library. If OpenCV is not installed in your system then first install it using This Method.

import cv2 
#cv2 is used for OpenCV library

Step 3

Now read the image from the location. In my case “F:\\AiHints” is the location and “top30.jpg” is the name of the image. Change it according to your image location and name.

image = cv2.imread("F:\\AiHints\\top30.jpg")
#imread is use to read an image from a location

Step 4

This code will convert the above jpg image into png and will save it at the location “F:\\AiHints”.

cv2.imwrite("F:\\AiHints\\top30.png", image)

Step 5

waitKey() open the image for a specific time in milliseconds until you press any key. “destroyAllWindows()” will destroy all the windows that we created.

cv2.waitKey()
cv2.destroyAllWindows()
