However, at 800圆00, it likely will be very easy to get a JPEG down under 1MB. (PNG, on the other hand, has the opposite behavior- it's best for logos, etc.) It does not do as well for logos, screen shots, or other images with "sharp" transitions from light to dark. JPEG does best for "true life" images, such as pictures from cameras. Obviously, depending on the image, the loss of visual quality may be substantial. All of this can be done without changing the image resolution. ![]() JPEG has a settable "quality" factor- you could simply keep reducing the quality factor until you got an image that was small enough. PNG is not a lossy image format, so you would likely need to convert the image into another format- most likely JPEG.
