To figure out the image size, just follow these simple steps:
- Multiply the width and height of the image, in pixels, to get the total pixel count.
- Multiply the total pixel count by 3 to get the image size in bytes.
- Divide the number of bytes by 1024 to get the image size in kilobytes.

What is the optimal image quality for a JPEG file?
I did an experiment with the image quality parameter of the imagejpeg () function when creating jpegs. I found the optimal image quality with file size is taken into account to be 80 – very close to the default value of 75. Anything over 80 results in an unnecessary increase in file size without much increase in image quality.
How to estimate the scaled size of a JPEG image?
I have successfully estimated the scaled size based on the DQT – the quality factor. I conducted some experiments and find out if we use the same quality factor as in the original JPEG image, the scaled image will have size roughly equal to (scale factor * scale factor) proportion of the original image size.
What is an image file size?
