Frequently Asked Questions
Will image compression reduce quality?
At 70-85% quality, the loss is imperceptible to the human eye. Our smart algorithm preserves visual key information. For lossless compression, use PNG or set quality above 95%.
Can I compress multiple images at once?
Yes. Upload multiple images and they will be processed with the same settings. Download all as a ZIP file.
Where are my images stored?
All processing happens in your browser locally. Images never leave your device. They are automatically cleared when you close the page.
What's the maximum image size?
Single image up to 50MB, no resolution limit. For best results, use web-sized images (2-10MB recommended).
