What Does Image Compression Do?
Image compression reduces the amount of data required to store an image. Depending on the selected format and quality setting, compression can reduce file size while maintaining an appropriate level of visual quality.
JPG, PNG or WebP?
JPG is commonly useful for photographs and images containing many colors. PNG can preserve transparency and is useful for graphics where lossless image data is important. WebP supports both lossy and lossless compression and can be useful for modern websites.
Is This Image Compressor Private?
Yes. Image processing is performed locally using your browser's built-in Canvas API. The page does not need to upload the selected image to a remote compression server.
