Compress JPG Online
Make JPG photos smaller in seconds, on your own device. Pick a quality level, watch the savings update live, and download — your pictures never touch a server. Camera files and phone shots are almost always bigger than they need to be, so the tool re-encodes them with your browser's image engine: at the default 75% most photos roughly halve with no visible difference, drop lower for web thumbnails, or push to 90%+ for high-detail shots. It's the classic balance — set the slider to the point where size and looks suit you. Works the same on desktop, tablet or phone.

Frequently asked questions
Are my photos uploaded anywhere?
Never. The compression is done by your browser's own image engine, on your device. Nothing is transmitted, stored, or logged anywhere else.
Which quality setting should I pick?
75% is a good default for photos and typically cuts file size by half or more with little visible change. Use 85–95% for prints or archival, 40–60% for web thumbnails.
Can I compress many files at once?
Yes — drop as many as you like. Every file is processed on your device, so batch size is limited only by your hardware.
Is it really free?
Yes, with no accounts, no watermarks, and no daily caps. There is no server cost to pay for because your device does all the work.
What is the difference between JPG and JPEG?
Nothing — they are the same format. JPEG stands for Joint Photographic Experts Group. JPG is just a shorter file extension that originated from older systems with three-character limits.
Will compressed JPGs look worse?
At 75% quality or above, differences are virtually invisible to the human eye. For social media, web use, and email, 70–80% is perfectly fine. Only pixel-level comparison reveals any change.
Can I compress PNG files too?
Yes — use our Compress PNG tool which uses lossless OxiPNG compression optimized specifically for the PNG format.
