Compress a JPG without losing quality

Balance size and sharpness yourself — see the exact file size before you download.

  • Your file never leaves your device — the server never receives or sees it.
  • Real compression via MozJPEG — the same encoder professional tools use.
  • See the exact file size before you download — balance size and quality with the slider.

How it works

  1. Choose a JPG

    Drag a file into the drop zone or open it with the button.

  2. Pick a quality level

    Pick the quality with the slider — see the exact file size before you download, so you know where to stop.

  3. Download the result

    The finished JPG saves straight to disk, no server queue involved.
