Will compressing my image reduce its quality?

JPEG compression is lossy, so some detail is discarded. At moderate levels the difference is hard to see. PNG uses lossless compression, so quality stays the same. The tool targets a 2 MB output.

What image formats does this tool support?

PNG, JPG (JPEG), and WEBP. If you have HEIC files from an iPhone, convert them to JPG first using the HEIC to JPG tool.

Is my image uploaded to a server?

No. Everything happens entirely inside your browser. Your image is never sent over the internet and no copy is stored anywhere. Once you close the tab, the file is gone.

How much can image compression reduce my file size?

Results vary, but it is common to achieve 40–80% file size reduction with minimal visible quality loss. Photos with large uniform areas compress especially well. Already heavily compressed images will see smaller gains.

Why would I want to compress images?

Smaller images load faster on websites, use less storage, and are easier to share via email or messaging apps. If your site is slow, oversized images are usually the first thing to fix.
