This page compresses JPG files. Compression re-encodes the image at a lower quality setting, discarding detail the eye is least likely to miss, and everything happens locally in your browser.
How it works
- Select your JPG files — several at once is fine.
- Set the quality level and watch the estimated saving.
- Compare the preview against the original before committing.
- Download the compressed files.
Good to know
JPG files respond differently to compression depending on their content. Photographs with smooth gradients compress well; images with sharp text or flat colour regions show artefacts sooner and are often better served by resizing or a format change.
Frequently asked questions
How much smaller will my JPG get?
It depends entirely on the source. Photos straight from a phone often shrink by 60 to 80 percent with no visible difference; files that were already compressed once have far less left to remove.
Can I undo the compression?
No. Compression is lossy and the discarded detail is gone for good, so always keep your original file. The compressed copy is a derivative, not a replacement.
