Why compress an image?

Large images take longer to upload and can use more storage or mobile data. Compressing an image reduces its file size, making it easier to:

  • attach to an email;
  • upload to an online application or website;
  • add to a blog or presentation;
  • share through WhatsApp or another messaging service;
  • save storage space on a device.

Compression can slightly reduce image quality. Use a moderate setting when the image contains text, detailed documents or important photographs.
