Shrink JPG photo file sizes with an adjustable quality slider — processed in your browser, never uploaded.

JPG is already a compressed format, but cameras and phones save at very conservative quality settings, leaving huge savings on the table. Re-encoding a photo at quality 65–75 routinely cuts the file by more than half with no visible difference at normal viewing sizes — and because this runs on your own device, batches of personal photos never touch a server.
How to Compress JPG
- Add one or more JPG photos (batch compression is supported).
- Set the quality slider — 65–75 is the sweet spot for most photos.
- Click "Compress images" and download the smaller files.
Frequently asked questions
What quality setting should I use for JPG photos?
For photos viewed on screens, 65–75 is usually indistinguishable from the original at a fraction of the size; go higher (80–90) for prints or images that will be edited again.
Why do some JPGs shrink more than others?
It depends how efficiently the file was saved originally — straight-from-camera photos often shrink 70–85%, while a JPG that was already optimized may only lose a little more.
Does repeated JPG compression damage photos?
Each re-save loses a little detail, so compress from your original once rather than re-compressing an already-compressed copy multiple times.
