JPEG [pronounced as jay - peg] is a commonly used method of lossy compression for digital photography (image). The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. Its usually used for photograph and is a bitmap type.
A photo of a cat compressed with successively more lossy compression ratios from right to leftPortable Network Graphics is a bitmapped image format that employs lossless data compression. PNG was created to improve upon and replace GIF (Graphics Interchange Format) as an image-file format not requiring a patent license. It lets you take the background off the image and focus on the image you want.
Scalable Vector Graphics (SVG) is a family of specifications of an XML-based file format for describing two-dimensional vector graphics, both static and dynamic (i.e. interactive or animated). The SVG specification is anopen standard that has been under development by the World Wide Web Consortium (W3C) since 1999. SVG images and their behaviors are defined in XML text files. This means that they can be searched, indexed,scripted and, if required, compressed. Since they are XML files, SVG images can be created and edited with anytext editor, but it is often more convenient to create these types of images with drawing programs such as Inkscape. Its basically for 2 dimension and its vector.
These are only a couple of file formats for images. There's a ton of them out there. Wouldn't it just be simpler if we only had one file format for images? It could be .IMG. Why do you think we have different file formats for images?
In a way it really would be easier to just have one file type but the problem with it is just that different files are good for different images. An image can look really good in one file and look messed up on the other hence the reason why there are so many different file types .
