Frequently Asked Questions

Absolutely. Our tool runs 100% locally in your browser. Your photos are never uploaded to any server, ensuring complete privacy and security.

Can I process images in bulk?

Yes! You can select hundreds of images at once. Our batch processing engine handles them efficiently and lets you download everything as a ZIP file.

How does quality adjustment work?

Lowering quality reduces file size by limiting the color palette (quantization) and applying compression. This is great for web optimization. Increasing quality (>100%) applies sharpening filters to enhance details.
