TinyPNG

TinyPng: The online PNG image compression tool is a tool that can help web designers optimize their images. With just two simple steps, it can achieve high compression of PNG images without affecting their quality. This can solve the problem of website loading speed caused by large images for web designers.

The TinyPNG tool can compress PNG within 1/3 while maintaining the alpha channel, and the compression loss is almost indistinguishable to the naked eye. However, the only regret is that it only supports uploading PNG images to the official website for compression and then downloading. However, TinyPNG provides a developers API, which is also based on HTTP. The free version can compress 500 images per month. The paid version supports more than 3500 images per month, but as long as there is an API, it can be updated independently.
