FAQ

How much can I reduce my image size?

Typically, photos can be reduced by 50% to 80% with virtually imperceptible difference in visual quality on web and mobile displays.

Does compressing images delete the original file?

No. The original file on your computer remains untouched. The browser creates a newly optimized copy for download.

Can I compress multiple images at once?

Yes! You can add multiple images at the same time and download them individually or as a single ZIP archive.

Is my data secure and confidential?

Absolutely. We do not operate an image processing backend; every compression computation occurs in your browser memory.
