How to Compress JPEG Files Online

Upload your JPEG file and use the quality slider to balance size vs quality. At 75-85% quality, most photos look identical to the original but are 50-80% smaller. The compression runs entirely in your browser.

Why Compress JPEG?

JPEG is the most common image format on the web and in photography. Even camera JPEGs can be significantly compressed further. Reducing JPEG size is essential for fast-loading websites, email attachments, and social media uploads.

Frequently Asked Questions

What quality setting should I use? For web: 70-80%. For print: 90-95%. Below 60% quality loss becomes noticeable in most photos.

Can I compress a JPEG multiple times? Yes, but each re-compression loses a bit more quality. Start from the original when possible.
