Compress images in your browser
This image compressor shrinks images entirely in your browser, so the file never leaves your device. Adjust the quality and optionally cap the width, and it re-encodes the image as an optimized JPEG, showing the before and after file size and how much smaller it got. It is good for shrinking photos before you upload or email them.
How to compress an image
Drop in or choose an image, adjust the quality and maximum width, and download the smaller version.
Frequently asked questions
Is my image uploaded anywhere?
No. All the work happens locally in your browser. Nothing is sent to a server.
What format does it output?
An optimized JPEG, which gives the best size saving for photos. Transparency is flattened, so use a PNG tool if you need transparency kept.
