JPEG uses lossy compression, so lowering the quality a little removes detail your eye won't miss and cuts the file size sharply. Set a quality level or a target size, optionally resize, and download. Nothing is uploaded.

Frequently asked questions
What quality should I pick?
75–85% is the sweet spot for photos on the web — visually near-identical at roughly half the size. Drop to 60% for thumbnails.
Is JPEG Compressor free?
Yes — JPEG Compressor is free with no account, no watermark, and no file-count limit.
Are my files uploaded?
No. The compression runs entirely in your browser with the Canvas API. Your files never leave your device.
Will quality drop?
You control it. A higher quality setting keeps the file closer to the original; a lower setting makes it smaller. Preview the output size before you download.
