About Compress JPG

JPG compression is a trade between size and detail, and the right point depends on the photo. This tool shows the result and the file size as you move the slider, so you can stop exactly where the image still looks right.

  • Re-saving a JPG at the same quality still shrinks it a little, since camera JPGs are stored at very high quality.
  • Avoid compressing the same JPG repeatedly; keep the original and compress once.
  • Metadata is stripped by default, which also saves a few kilobytes.

How to use it

  1. 1Drop your JPGs.
  2. 2Move the quality slider and compare the preview.
  3. 3Download the compressed files.

Questions

What quality should I use?
80 for web and sharing, 90 for printing, 60 to 70 when the file must be very small.
Can I compress many at once?
Yes. Drop a whole folder and download the results as a zip.
Are photos uploaded?
No. Everything runs in your browser, so your photos never leave your device.
