Free online image compressor
PixelTools is a free online image compressor that lets you reduce the file size of JPG, PNG, and WebP images directly in your browser. Compressing images can make them easier to share, store, upload, and use on websites.
Image compression works by reducing the amount of data required to represent an image. Depending on the format and compression settings, you can often achieve a substantial reduction in file size while keeping the image looking sharp.
For JPG and WebP images, PixelTools lets you adjust the output quality. Higher quality generally produces a larger file, while lower quality can produce a smaller file. This gives you control over the tradeoff between visual quality and file size.
WebP can be an especially useful format when optimizing images for websites because it can provide a strong balance between quality and file size. JPG remains a practical option when broad compatibility is important.
PixelTools processes the image directly in your browser, so the image does not need to be uploaded to a remote server for the compression operation.
