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.
Is my data transmitted to a server?
No. UltraUtils uses client-side processing technology. Your images are processed entirely within your browser and never uploaded to our servers.
Is there a watermark on the output?
No. Our tool is 100% free and does not add any watermarks to your optimized images.
