JPEG (.jpg)
JPEG is an alternative to GIF developed by the Joint Photographic Experts Group specifically for photographic images. JPEG supports millions of colors (24-bit). The JPEG format is best for scanned photographs, images using textures, images with gradient color transitions, or any images that require more than 256 colors.
JPEG is a lossy format, which means that some image data is discarded when the image is compressed, reducing the quality of the final file. However, image data can often be discarded with little or no noticeable difference in quality. The amount of data discarded during compression is determined by the Quality setting you choose for the file.
Choose from the following JPEG export options:
![]() |
Image Quality enters the percentage of quality to maintain when exporting as JPEG. A higher quality setting preserves more image data but yields a higher file size. A lower quality setting discards more image data but yields a smaller file size. |
![]() |
Progressive JPEG creates an image that downloads as a series of overlays in a browser, enabling a viewer to see a low-resolution version of the image before it is fully downloaded. |
