Free Image Compressor

Make JPG, PNG and WebP images smaller before they slow your site down. Resize them, convert them to WebP and download the lighter files. Everything happens in your browser: your images are never uploaded.

75–85 suits most photos. Higher keeps more detail and makes bigger files.

    How to use the Image Compressor

    1. Drop up to 20 JPG, PNG or WebP images onto the box.
    2. Choose WebP (smallest for websites), a maximum width (1600 px suits most content images) and a quality (75–85 suits most photos).
    3. Compare the sizes, then download each file or all of them.

    Images are compressed with your browser's built-in canvas encoder; they are never uploaded.
