What this tool does

This page re-encodes JPEG or JPG input as JPG and can lower encoding quality to meet a maximum size. JPG compression is lossy, so review the output before downloading.

How to use it

  • Choose a JPEG or JPG image.
  • Set the maximum size and keep or adjust the dimensions.

Check the output

Real limitations

  • Transparency is not supported in JPG.
