What Is an Image Compressor?
An image compressor reduces the file size of your JPG, PNG, WebP or TIFF images while keeping the quality as high as possible. This online, free tool compresses your images on the server using pngquant and jpegoptim, so you can shrink one photo or a whole batch and download everything as a ZIP. Smaller files mean faster sites, quicker uploads, and emails that send without a hitch.
