Compress JPEG

About this tool

Reduce the file size of your JPEG images for faster uploads, smaller email attachments, or quicker-loading websites — processed entirely in your browser with an adjustable quality slider.

Frequently asked questions

How much smaller will my JPEG get?

It depends on the image and quality setting — typically 30–70% smaller with minimal visible quality loss at default settings.

Will compression ever make my JPEG bigger?

No — if our compressed result would be larger than your original, we automatically return the original file instead and tell you it's already optimized.

Is my JPEG file uploaded anywhere?

No, compression happens entirely in your browser.

Can I compress multiple JPEG files at once?

Yes — select multiple files and download them together as a ZIP.
