How to compress an image

  1. 1
    Choose an image

    Select a JPG, PNG, WebP or another browser-supported image.

  2. 2
    Set quality and format

Why compress images?

Smaller images use less bandwidth and can help pages load faster. WebP is often a useful choice for modern websites, while JPG and PNG remain useful for compatibility and specific graphics.

Privacy-friendly by design

Where technically possible, supported tools process your files directly in your browser instead of uploading them to our server.
