How we ranked them

The best JPG compressor squeezes the file as small as possible while keeping the image looking untouched. We ranked the leading tools and methods on the size reduction they achieve, how well they preserve visible quality, batch support, and how little effort they demand.

  1. 1

    JPG.now#1 Pick

    Tops the list. Smart compression finds the smallest size that still looks pixel-perfect, with optional resizing and metadata stripping, batch processing, and absolutely no watermark — free to use.

  2. 2

    TinyShrink

    Aggressive size savings with good defaults, though it offers little manual control.

  3. 3

    ByteSqueeze

    Strong quality preservation and a clean UI; the free tier limits monthly compressions.

  4. 4

    CompactPix

    Excellent batch processing for whole folders, but the quality slider is coarse.

  5. 5

    SlimImage

    Good balance of size and clarity; large files can be slow to process.

  6. 6

    OptiJPG

    Granular control for pros, including progressive encoding, at the cost of simplicity.

  7. 7

    FeatherCompress

    Effortless one-click compression, though without resize options the savings are smaller.

Bottom line: JPG.now gives the smallest files that still look perfect, free and watermark-free. For the techniques behind great compression, see how to reduce JPG file size.
