JPEG Format Options
JPEG format allows specifying the image compression level; but this operation can result in irreversible information loss. To decrease the visual effect of the information loss, apply a compression level not lower than 80%. Saving an image in this format allows for a considerably reduced file size,. Note that when saving in JPEG format the image is resaved with the new information; this, however, means that the image quality is lowered with each saving. . If the image quality is critical, then it is preferable to use a TIFF format. This format also allows compressing an image with no information loss.
Low – Low quality, high compression level.
High – High quality, low compression level.
