Tool Introduction
This tool is used for online compression of PNG images/JPG images/JPEG images/other common format images. Tool advantages: 1. Images will be automatically compressed after upload or quality adjustment. 2. You can freely set the compression quality to find the best balance between quality and size. You can preview the compressed image, compare it side by side with the original, and choose the most suitable compression quality. You can click on the before and after images to preview them in large size, checking if the compression effect has been achieved while maintaining the quality. 3. The size, compression rate, etc. of the images before and after compression are clear at a glance, making it more convenient to meet different compression needs. 4. Compression is carried out entirely using the browser's API on your local machine, without any interaction with the server, ensuring the safety of your private information. 5. We compress PNG images through a combination of color quantization, Alpha channel optimization, filter optimization, and DEFLATE compression. Although some steps may cause some information loss (e.g., color quantization), the compression is lossless in most cases and does not change the visual effect of the image. Its flexibility and efficiency make it an ideal choice for PNG image processing in web development. 6. Different compression mechanisms are used for PNG format and other formats. 7. We compress without changing the original image format, using the same format as the original for output. If you have bulk image compression needs and want to compress a large number of images at once, you can use our bulk image compression tool.
