• Lossless compression: Images are stored without any loss of
quality. Tends to make large files when used with photographs.
Recommended for other kinds of images or graphics.
• JPEG compression: Allows for varying degrees of quality. A
setting of 90% works 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 a resolution
of 72dpi (for Windows) or 96dpi (GNU/Linux) is sufficient, while
for printing it is generally preferable to use at least 300 or 600
dpi, depending on the capability of the printer. Higher dpi
settings greatly increase the size of the exported file.
