There are lots of discussions over the image formats used for the web, namely what image format is most appropriate. The discussions refer to the file size and its influence on site performance and quickness of pages downloading – factors crucial for the website owner. There are several image formats most appropriate for the web, where PNG, GIF, and JPEG are most widely used. Depending on the purpose, all the 3 image formats are popular, and each has advantages and disadvantages. The main reason to convert JPEG to PNG is the ability of the latter one to support transparency. The PNG format transparency is variable and allows applying image effects on PNG images. The advantage of PNG over JPEG is that it supports lossless compression algorithm, so the quality of the file saved is not degraded. Although JPEG does what it can to retain the highest image quality possible alongside with a small file size, it cannot compete with PNG which is lossless by default. PNG images can be true color up to 64 –bit, grayscale and indexed color. Due to PNG ability to support progressive rendering, web pages load pretty fast. ImageConverter Plus provides comprehensive support of the PNG format. The choice of compression level ImageConverter Plus offers is from 0 up to 9 (the highest), but this option is more suitable for our advanced users. Compression level set by default is 5 which is perfectly acceptable for fulfilling most of the conversion tasks.
