JPEG Files:
1.The JPEG file format has been around for many years, and is support by every image editor and web browser on the market. It is also supported by every digital camera, and any video camcorder that can also take pictures. Every digital photo print shop also supports the JPEG standard.
2. Doesn’t take up much storage space.
3. The compression algorithm is “lossy”, which means data is discarded when the file is compressed. For the most part, however, you won’t notice any loss of data – unless you start to edit the file.
4. The more compression you use, the more artifacts may appear. These usually look like “smudges” in the image, and can really reduce the quality of the image.
5. All the settings from the digital camera have already been applied to the JPEG. This can be a downside if, for example, you had the wrong colour balance set, then your digital pictures would have a colour cast to them.
PSD Files:
1. PSD files tend to be extremely large, since these lossless images use no compression. This preserves all image information, but can make the file itself unwieldy and difficult to email or transfer
2. Can preserve layers. PSD files can handle simple vector layers, making them more suitable for importing and exporting data from programs like Adobe Illustrator. PSD also supports masks, color profiles, alpha channels and spot colors.
3. The PSD format is a proprietary Adobe file format. The company does not release its specifications to the general public. PSD support is often inconsistent outside of Adobe’s products
4. PSD files’ large size and capability to save significant amounts of file information make them an excellent choice for working files.
5. Very few other programmes will understand open or import psd files.
