3, use programming language implementation: for example, Python has a PIL library that can be used to process the image by reading the JPG image and adjust its quality and size. Here is a simple example:
` `python
fr
om PIL import Image
img = Image.open('input.jpg')# Open image
new_img = img.resize((800, 600))# Set a new size
new_img.save('output.jpg', 'JPEG', quality=90)# Save the image in JPEG format and set the quality to 90
