How much does quality drop during compression?

At the default 80-90% quality, it's nearly impossible to see a difference with the naked eye. This range is recommended for most uses.

Can I process multiple photos at once?

Currently, we provide a per-photo approach for precise optimization. A bulk batch processing feature is coming soon.

What is the maximum upload size?

We recommend under 20MB per file. Larger files can be processed, but speed may vary depending on your browser environment.

Is there a risk of my photos leaking to the server?

Absolutely not. All processing in UltraUtils happens locally in your browser. No data is ever sent to our servers.
