PNG has long been a web standard and one of the most common image formats used on the web. If you need an image on a transparent background, PNG is the best option. The main application is internet use and graphics editing. PNG does not allow to create animated images and the compression ratio is not much higher than the previous formats. Unlike JPEG, saving a digital file as PNG does not degrade its quality. This format supports not only transparency, but also translucency from 1% to 99%, which is a big plus. PNG is an image with a transparent background and often weighs more than its JPG counterpart. PNG is a raster graphics format that uses lossless compression and can be 48-bit color. JPEG is ideal for web images that need to load quickly. They can be easily sent from phone to phone, by email or posted on the Internet. You can work with a raster in such convenient and well-known editors as Adobe Photoshop and Paint. JPEG is a flat image format, which means that all changes are saved in a single layer, so it is not very suitable for editing and working with layers.Ī few years ago, the JPEG2000 (.jp2) format was created, which uses a more powerful compression algorithm, but has not been able to supplant its progenitor. The reason for such widespread use is the rather good quality and small file size. It is widely used in digital technology (cameras). JPG files are supported by all image viewers and editors.
And this helps to economize on hard disk space. The compression ratio can be set in the settings of graphics programs - the lower the quality, the smaller the image file, and vice versa, the higher the quality, the larger the file is. Lossy compression is used, that is, you choose what quality should be, as a result of which the size of the resulting file is determined. Its peculiarity is that when compressing, you can make a choice either in favor of quality or size. JPEG is perhaps the most famous bitmap format.
