Why this matters

JPG is the most common photo format on the web, but unedited photos from phones and cameras routinely weigh 5–10 MB each. That makes web pages slow, blows past email size limits, and burns through cloud storage. Compressing JPGs strips redundant data and lowers quality just slightly — usually invisibly — so a 6 MB photo becomes 600 KB without anyone being able to tell.

Step by step

  1. 1
    Open the JPG compressor
    Drag your JPG or JPEG files onto the upload area, or click to browse.
  2. 2
    Choose a target size
    Set the maximum file size you want, in MB or KB. The compressor automatically dials in quality to hit your target.
  3. 3
    Preview the result
    Compare the original and the compressed JPG side by side. Adjust the target if it’s too aggressive.
  4. 4
    Download
    Click download. The compressed JPG saves to your device — never uploaded anywhere.
  5. 5
    Repeat or batch
    Process more JPGs one at a time, or use the Batch Photo Editor to compress dozens at once.

Frequently asked questions

How much can I compress a JPG?

Most photos compress 60–90% with no perceptible quality loss. Photos already saved at low quality won’t shrink as dramatically.

Will compressing reduce JPG quality?

JPG is a lossy format, so yes — but the loss is usually invisible until you push compression past 70%. Our defaults stay in the safe zone.

Is my JPG uploaded to a server?

No. The compressor runs entirely in your browser using JavaScript and Web APIs. Files never leave your device.

What size should I compress JPGs to for email?

Most email providers cap attachments around 25 MB. For a single embedded photo, aim for under 1 MB; for multiple, aim for 200–500 KB each.

Does this work on iPhone HEIC photos?

Convert HEIC to JPG first using the Image Format Converter, then compress.

Can I compress hundreds of JPGs at once?

Yes — use the Batch Photo Editor for bulk JPG compression with the same settings applied to every image.
