Frequently asked questions

How much smaller will my image be?

It depends on the image, but typical savings are 40–80%. Photos and screenshots compress the most. The tool shows the exact before/after size and percentage for every file.

Does compressing reduce quality?

Lossy compression discards some detail, but at sensible quality settings it's hard to notice. Use the slider to balance size against quality — you see the result immediately.

Are my images uploaded to a server?

No. Unlike most online converters, nothing is uploaded to a server. The conversion happens entirely inside your web browser using your device's own processing, so your images never leave your computer or phone. You can even disconnect from the internet after the page loads.
