JPEG is a raster format that is widely used on Internet pages. It is possible to store scanned images as JPEG files and edit them later with a wide range of programs. JPEG is a pure pixel-based format, i.e. when exporting to JPEG, all the elements drawn in Arbortext IsoDraw are converted into a raster image.

JPEG is particularly suitable for grayscale and color images. PNG and TIFF with Fax Group 4 compression are more suitable for black and white images (bitmaps).

A particular characteristic of the JPEG format is that compression affects the quality of an image. It is possible to compress an image more in order to obtain a smaller file, however this does reduce the quality of the image.
