JPEG and JPG are the same format
The two extensions name the same image format. Changing .jpeg to .jpg alone does not reduce file size or change image quality.
Before you compress JPEG to JPG online
Actual compression requires re-encoding the image or reducing its dimensions. Lower quality can create visible artifacts. Keep the original and compare the result at the size you plan to display it.
Compression after WebP conversion
