![]() ![]() Unlike GIFs, SVGs, and PNGs, JPEGs cannot have transparent backgrounds. Can JPEGs be transparent or have a transparent background? JPEG files are smaller than other file types, so they’re easy to download and share. It’s best used for photos and other images with lots of colors.īy the way, JPEG stands for Joint Photographic Experts Group – the team that developed the standard. JPEG is the most common file type for images. You will see both the terms "Lossless" and "Lossy" appear below when we describe different image file formats. Lossy compression permits reconstruction only of an approximation of the original data (though usually with greatly improved compression rates). Lossy in that it loses some of the information. This is where "Lossy" compression comes in. There is only so much you can compress a file before you start throwing away some of the information that file contains. Lossless compression is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data. Lossless vs Lossy – What is the Difference Between These Two Compression Types? If you want to go much deeper on the performance side of things, read these guides on how to optimize your website's images for the web.įirst, a quick explanation of how image compression works. Note that this is a short, non-technical article. In this tutorial, we’re going to explain the most common image file types, and when you should use them. Which format is best for what application? When you’re working with images, it’s important to understand the different file types. ![]()
