Frequently Asked Questions

How does compression work?

The tool uses canvas-based resampling to re-encode the image at a lower quality setting, reducing file size while preserving visual appearance.

Is my image uploaded to a server?

No, all processing happens in your browser using HTML5 Canvas. Your image never leaves your device.

What quality setting should I use?

80% quality provides a good balance. Below 60%, artifacts become noticeable. For web images, 70-85% is typically ideal.
