It is usually best to save product images for web usage in the JPEG image compression format. The JPEG format will save an image with good compression value.
When saving, select a relatively high quality, such as 80% (in PhotoShop) or “High Quality” or “Best Quality”.
File formats that we can work with:
.jpg (preferred)
.png
.tif
.eps
.psd (Photoshop Files)
tip: Whenever possible, files should be saved in the RGB color format. CMYK color files will need to be converted to RGB before uploading to the web.
