Convert HTML to JPEG

.html

HTML – is a special format associated with web pages developed using the appropriate markup language. Links link a lot of pages from websites. Text editors modify files with a similar extension since they are a standard text document. However, to avoid incorrect display, it is recommended to use specialized software, for example, Adobe Dreamweaver. All modern browsers allow you to open HTML files, but the source code is not displayed by default. It can be viewed in the web browser menu by selecting the "View source" category or using a text editor. Files with the HTML extension include text content and links in the form of text to external objects, for example, a picture inside an article.

The HTML language was created by T. Berners-Lee to exchange scientific and technical information by people who do not have in-depth knowledge in the field of imposition. It is based on the use of multiple tags enclosed in angle brackets. Modern browsers easily interpret the HTML4 language by providing the user with formatted text. Now there is a fifth version with the DOM specification (formerly SGML).

JPEG – is a popular graphic file format, which is characterized by a high degree of compression, which leads to a decrease in image quality. It uses the technology of encoding smooth color renditions, providing the ability to reduce the amount of data frequently during the image recording. Because of the small size, it is requested by the owners of websites, allowing you to save the traffic effectively. It is also frequently used in memory cards of digital video cameras. The JPEG algorithm is optimally suitable for compressing photographs and pictures in which realistic scenes with little contrast of colors are present. It is not recommended to use this format to compress drawings and various graphics since a big difference between several near located pixels provokes visible artifacts.

The procedure for compressing the digital images in JPEG format is carried out in several stages. First, the photo is transformed into a color space YCbCr. Then it is divided into squares to determine the upper range of the color spectrum. Finally, the colors and brightness are coded. JPEG uses a "lossy" compression system and discrete cosine transform technology. The format acts simultaneously as the standard of ISO and the International Telecommunication Union. The file compression ratio is in the range from 10:1 to 100:1. In this case, the reduction in image quality can vary from insignificant to substantial.
