ImageConverter Plus can perform lots of transformation among various graphic files. The number of image formats supported by our software is really large – about 200 formats and their dialects. So, you don’t have to worry about the image formats for your particular task related to the web – you can simply convert one format to another. The main web graphic formats are GIF, JPG, and PNG. It’s important to know the differences and choose the best format for each image, so that pictures look good and are as compact as they can be so they appear quickly on your site visitor’s screen. On average, images make up over 50 percent of the average web page, so it is important to minimize their impact on page speed. Choosing the appropriate web-based format for your images is the first step towards optimized web graphics. JPEG uses a lossy compression structure that allows the users to compress the data up to 1/10 of the original size. Such high compression results in a loss of image quality, but on the web pages the images are generally small and they need the compression to produce the smaller image file sizes for downloading. Index-color formats like GIF and PNG are ideal for low- and flat-color images like logos, buttons, and graphic text. Use GIF files for images that have a small number of colors. GIF files are always reduced to no more than 256 unique colors. The compression algorithm for GIF files is less complex than for JPEG files, but when used on flat color images and text it produces very small file sizes. PNG graphics have a better compression rate than GIF images which result in smaller images than the same file saved as a GIF. PNG files offer alpha transparency as well as animation.
