How it works

  1. Download and open CompressEasy Desktop.
  2. Drag in a folder of images.
  3. Choose a strength preset and save the optimized files.

No upload, ever

Unlike web tools, an offline compressor keeps your photos on your device. That matters for client galleries, product shots and personal images.

Works without internet

Because the codecs run locally, you can compress on a plane, in the field, or anywhere with no connection.

Fast batch processing

Drop hundreds of images and let the app churn through them with native-speed encoders.
