Auto keeps photos as JPG and turns PNGs into WebP, which keeps transparency at a fraction of the size.
Frequently asked questions
Are my images uploaded?
No. Compression runs on your device using your browser's built-in encoders, so photos never leave your computer.
What quality setting should I use?
70–80% is a good balance for photos on the web. Below 60% artifacts become visible.
Why did a PNG become WebP?
In Auto mode PNGs are converted to WebP, which keeps transparency and is usually much smaller. Pick PNG to keep the format.
