TinyPNG

An online image compression tool, called TinyPNG, which is able to help users optimize their images easily, including converting images to WebP format or compressing large numbers of images efficiently to reduce file size. The tool supports uploading up to 20 images at a time, no more than 5MB each, and automatically converts image formats. TinyPNG offers a variety of products and services, including Web Pro and Web Ultra subscription plans, as well as API integrations and WordPress plugins, designed to provide website owners, developers, and designers with customized solutions to ensure optimal website performance for each project.
In addition, TinyPNG also emphasizes its commitment to user privacy, promising to keep uploaded images for up to 48 hours and delete them permanently thereafter.

TinyPNG uses Smart Distortion Compression technology to reduce the size of WEBP, JPEG and PNG files, reducing the amount of data that needs to be stored by selectively reducing the number of colors in an image, thus significantly reducing the file size with little impact on image quality. The tool supports WebP, JPG, PNG and APNG (Animated PNG) formats and is constantly expanding the range of formats supported. TinyPNG also provides a drag-and-drop web page optimizer that allows users to upload up to 20 images for free for compression, and offers Web Pro and Web Ultra subscription plans to meet the needs of different users.
In addition, TinyPNG also provides detailed Privacy Policy and data processing operation information to ensure that the pictures uploaded by the user are only accessible by the user and deleted within a certain period of time.
