About JPG compression
JPG stores photos using lossy compression tuned for human vision. Reducing the quality setting removes high-frequency detail first, which is why moderate settings look nearly identical to the original.
Need it even smaller?
Converting to WebP typically saves more space at the same visual quality, and every modern browser can display it.
Frequently asked questions
Are my images uploaded?
No. This tool decodes and re-encodes your images inside your browser tab using built-in browser features. The files never leave your device unless you choose to share the downloaded results.
Is there a JPG vs JPEG difference?
No — they're the same format. The three-letter .jpg extension dates back to older systems with short file extensions.
