Many websites have strict rules that limit the size and type of image format you’re allowed to upload. With JPG being the go-to file format of the internet, we’re going to take a look at how you can convert your images into JPG format.
What Is a JPG File?
JPG (or JPEG), is a popular file format used for images and graphics — especially on the internet. It was created by the Joint Photographic Experts Group (JPEG) and uses a compression algorithm that reduces sections of an image into blocks of pixels. It’s able to compress up to a ratio of 10:1 without any noticeable degradation, depending on your settings. This alone is one of the main reasons why JPG has become the de facto standard of images on the internet.
However, all that compression doesn’t come without a loss. JPGs are a “lossy” file format, meaning that during the compression procedure, redundant blocks are permanently deleted. The more you compress a file, the more data you lose and subsequently the worse your final image is going to look after multiple iterations through the algorithm.
Here’s an example of an image that has been way overcompressed.
Still, when used properly, JPG delivers decent-looking images with small file sizes. Whether you’re sending one in an email, posting a meme on Reddit, or uploading your vacation pictures to Facebook, because of its ability to compress images at such a high rate, your final file is a fraction of its original size.
