How to use it

Compress JPG, PNG or WebP images for websites, email or sharing without sending them to a server. Choose the available quality setting and compare the original and output sizes. PNG re-encoding may not reduce every file because browsers do not expose a PNG quality control.

  1. Choose a JPG, PNG or WebP image.
  2. Adjust the available quality setting and start compression.
  3. Compare the sizes, then download the result you want.
