JPG is the standard format for photos, but files straight from a camera or phone are often 3–10 MB. This compressor re-encodes them with MozJPEG, an optimised JPEG encoder that produces files about 10% smaller than typical encoders at the same quality, and removes hidden metadata.
How to compress a JPG
- Step 1
Add your JPG or JPEG photo.
- Step 2
Set the quality (75–85 is a good balance) or a target size in KB.
- Step 3
Check the preview and download the smaller JPG.

Frequently asked questions
What JPG quality should I use?
For websites 70–80 is ideal. For printing or archiving use 85–92. Below 60, blocky artifacts start to appear.
Does it keep the photo’s orientation?
Yes. Rotation from the camera is applied to the pixels, so the photo stays upright after metadata removal.
Can I compress several JPGs at once?
Yes — use the bulk image compressor to process many photos and download them as a ZIP.
Are my images uploaded to a server?
No. This tool runs entirely in your browser using WebAssembly. Your images never leave your device, and nothing is stored.
