JPEG Quality
JPEG Quality is a setting which controls the amount of data
lost in lossy compression when
files are saved in the JPEG
file format.
In most paint programs,
you can find a setting in the Save As dialog to
control the JPEG Quality:
- Higher Quality values generally lead to less data
loss, higher quality images, fewer
artifacts, but larger
file sizes.
- Lower Quality values generally lead to more data
loss, lower quality images, more
artifacts, but smaller
file sizes.
In some paint programs the
setting may be labelled differently (for example "Compression"
and/or "Smoothing") although the general effect is the
same (higher Compression/Smoothing is equaivalent to lower Quality,
and lower Compression/Smoothing is equivalent to higher Quality).
