WEBP is an image compression format that was introduced by Google in 2010. Its main advantage is its low size without visible loss of quality compared to formats such as JPEG or PNG. Therefore, it is quite logical to use this format for storing images on the site, especially if you do not need to store the original images on the site.
After a long search, I still did not find a ready-made and simple solution that would support converting images to WEBP format on the fly.
Therefore, I decided to write my own version, which eventually consists of a couple of dozen lines and is as simple as a wooden board.
