D1 evaluate how different delivery mediums for graphics influence file formats WEB –  we are using web delivery very often for different purposes starting from sosial media and finishing with media sharing. All of these areas need a catchy experience. Nowadays people do not relay on word description but very often on pictures and how they are presented is key to success. JPG is probably the most common image format used on the web. It is very compatible and can boast a small file size with very little noticeable loss of quality. JPG is compressed using what is called “loss” of compression, which means that the quality of the loss always persists. This loss is especially noticeable in the text and in small details. Known as “artefacts,” this loss of quality looks like small, blocked elements. Look at the difference in the following comparison, especially around the detailed edges of flower petals.JPG compression is still optimized for photos, making artifacts virtually invisible to the naked eye. But do not forget: every time the photo is saved, the number of artifacts will increase. Always leave a good idea to keep a copy of your original lossless compression.JPG stores DPI information (dots per inch) and remains the standard format for printing. However, they do not support the transparency of the background and can not be easily applied to other elements. When you save a JPG image, it is definitely the best choice compared to a lossless format, such as PNG. The following example does not show a noticeable visual contrast. The size of the file, however, is doubled by size.PNG is another very common and versatile image format that is discovered on the Internet today. With lossless compression, you can save PNG and not lose quality. However, this (in most cases) will give a very large file size. PNG is not an option when it comes to printing, since it does not support the 4-color process (CMYK). PNG is the best format for screenshots, and most computers will automatically save screenshots as PNGs. PNG compression is optimized for graphic images and images that use less than 16 colors. If you follow us on Facebook, you are familiar with our weekly fonts. These graphs are stored as PNGs. Note the difference between the PNG version and the JPG version.GIF is a growing force on the Internet now. This format is an excellent choice for limited color images that should be small in size. Photos and full color images saved in GIF format will result in high compression with a noticeable loss of quality.The unique feature of the GIF format is its ability to be animated. Despite the fact that in recent years, this functionality has declined, accurate and focused animation with a GIF image can only draw attention to the call to action or other event on your site.TIF is known as the most popular image format, is best used for commercial work and should not be used on the Internet. Keep a copy of TIF for original photos as it provides lossless compression. However, if you are using the Internet, be sure to export as JPG.
