• Lossless compression: Images are stored without any loss of
quality. Tends to make large files when used with photographs.
Recommended for other images.
• JPEG compression: Allows for varying degrees of quality. A
setting of 90% tends to work well with photographs (small file
size, little perceptible loss).
• Reduce image resolution: Lower-DPI (dots per inch) images
have lower quality. For viewing on a computer screen generally a
resolution of 72dpi (for Windows) or 96dpi (GNU/Linux) is
sufficient, while for printing it is generally preferable to use the
highest dpi value. Note that the dpi setting affects the size of the
exported file considerably.
