Is it supported everywhere?Įxcellent question! The files produced by TinyPNG are displayed perfectly on all modern browsers including mobile devices. I have excellent eyesight but can’t spot the difference either! Use the optimized image to save bandwidth and loading time and your website visitors will thank you. In the above image the file size is reduced by more than 70%. The result better PNG files with 100% support for transparency. All unnecessary metadata is stripped too. By reducing the number of colors, 24-bit PNG files can be converted to much smaller 8-bit indexed color images.

In this case, the reduction in image quality can vary from insignificant to substantial.File size 57 KB vs Shrunk transparent PNGĮxcellent question! When you upload a PNG (Portable Network Graphics) file, similar colors in your image are combined. The file compression ratio is in the range from 10:1 to 100:1. The format acts simultaneously as the standard of ISO and the International Telecommunication Union. JPEG uses a 'lossy' compression system and discrete cosine transform technology. Finally, the colors and brightness are coded. First, the photo is transformed into a color space YCbCr, and then it is divided into squares to determine the upper range of the color spectrum. The procedure for compressing the digital images in JPG format is carried out in several stages. A strong contrast between several near located pixels provokes the appearance of visible artifacts. It is not recommended to use this format for compression of drawings and various kinds of graphics. The JPG algorithm is optimally suitable for compressing photographs and pictures in which realistic scenes with little contrast of colors are present.

It is also frequently used in memory cards of digital video cameras. Because of the small size, it is requested by the owners of websites, allowing you to save the traffic effectively. It uses the technology of encoding smooth color renditions, providing the ability to frequently reduce the amount of data during the image's recording. JPG – is a popular graphic format characterized by a high image compression rate, which leads to a decrease in image quality.
