![]() The top image is compressed at 80% quality, while the bottom is full quality JPEG. Can you tell which is compressed at a lower quality? That file size savings will definitely be noticable though. But as this really cool interactive blog demonstrates, depending on the content of the image, you can get away with exporting at a significantly lower quality setting without seeing a difference. In general, you can always export at 90% quality and won't notice a difference with your naked eye. ![]() The JPEG file format is compressed, but you can choose the level of compression in almost any image editing software. ![]() That means all product images, sliders, collectgion images should all be saved as JPEGS. file formats, so let's just skip all the technical jargon and get to the point: If the image doesn't have any transparent parts (like, for instance, your store's logo might), it should be saved as a JPEG (or JPG.they're the same thing). Most people would have to use a lifeline on Who Wants To Be a Millionaire (is that show even still on the air?!) if asked the differences between TIFF, JPEG, PNG, GIF, BMP, etc. Image size is different than file size, and file sizes are largely dependent on the file format. Sliders and other images on your site will depend on your theme, but in general, there's rarely a need to be over 3000 pixels wide. We recommend saving product images as 3000 x 3000 pixels at 72 dpi (dots per inch). The first problem we often see is people using way too large an image size on their site. Striking a balance between good looking images and a site that takes forever to load can be tricky, but here are some tips to help. By shrinking file sizes across the board, even by a little bit, you'll significantly increase load time speeds. Your site has hundreds or thousands of images. Websites are image-heavy these days, but every customer isn't running on a gigabit speed internet connection, so it's still important to make those image files as small as possible to speed up load times. Optimizing images for faster site load times
