Frequently Asked Questions
How much can I reduce image file size?
Typical reductions range from 40% to 80% depending on the original format, resolution, and your quality settings. JPEG images often compress more than PNG images with transparency.
Does compression reduce image quality?
Some quality loss occurs with lossy compression (JPEG, WebP), but at moderate settings the difference is imperceptible to most viewers. The preview lets you judge the quality before downloading.
Is my image uploaded to a server?
No. All compression is performed locally in your browser using client-side processing. Your images never leave your device.
