About this tool

Cameras and phones save JPGs at very high quality settings that most uses don't need. Re-encoding at 75–85% quality routinely halves the file size with no visible difference at normal viewing sizes — useful for email limits, form uploads and faster web pages. Because each JPG re-encode is lossy, compress from your original file rather than compressing the same file repeatedly.

Frequently asked questions

How small can I make a JPG before it looks bad?
For photos viewed at normal size, 70–85% quality is usually indistinguishable from the original. Below about 60% you may notice blockiness around edges. The size readout helps you stop at the right point.
Does compressing change the image dimensions?
No — width and height stay the same. If you also want smaller dimensions, run the file through the Image Resizer, which reduces size even further.
Are photos uploaded to your server?
No. Compression runs in your browser; the file never leaves your device.
