How to reduce image size?

  1. Upload your image file using one of the methods above.
  2. Toggle the image quality to optimize your result. (optional)
  3. Start the compression by clicking on "Start".

Using PNG compression reduces the file size of larger files such as TIFF, NEF, CR2, and other raw camera images.

PNG itself is a versatile format that is widely used across the web, especially because it supports transparency (alpha channel).
