Unlike raster formats seen in JPG, GIF, and PNG, an SVG image remains crisp and clear at any resolution or size. The latest of all the file types, SVG (Scalable Vector Graphics) is a vector image file format released in 2001, and is more powerful than other file formats suitable for the web. It’s the only raster format of the four that supports transparency! SVG Like the GIF, PNG is lossless, so you do not lose any data during compression, and they’re ideal for detailed graphics, or when you’re working with files that are still being edited. PNGs are most often used for static images, like a JPG would, however they can support animation. PNG-24, like JPGs, can support up to 16 million colors. PNG-8 is similar to GIF in that it supports 256 indexed colors, as well as transparency. If the size of your file is not a pain point, and you’re working with a more complex image, PNG is probably the best choice. PNG (Portable Network Graphics) was invented in 1995 to replace the GIF and to get around some pesky patent issues. GIF was intended for small, simple graphic icons, but with one important caveat - they can be animated! There is no audio associated with a GIF, but they are still a powerful way to bring motion to your online channels. GIFs are “lossless” - meaning that a GIF retains all the data contained in the file, but they are smaller than JPGs, specifically because they only accommodate up to 256 indexed colors. GIF (aka, Graphics Interchange Format) came on the scene in 1987 specifically to take the pain out of sending images to or from slow connections, or low bandwidth. Think of JPG as the default file format for uploading pictures to the web, unless they need transparency, have text in them, are animated, or would benefit from color changes (like logos or icons). That means that some quality will be lost or compromised when any file is converted to a JPG. The JPG is “lossy” - which means that when the data is compressed, unnecessary information is deleted from the file permanently. In fact, most digital cameras and smartphones save your pictures as JPGs. They work well on websites, and are the best choice when posting on social media channels. JPGs can support millions of colors, so this file type is ideal for real-life images, like photographs. This image format takes up very little storage space, and is quick to upload or download. JPG (Joint Photographic Experts Group) was created in 1986.
