FAQ

Q: Are images uploaded to the server?

No. All processing happens in your browser. Images never leave your device.

Q: What if only one dimension is filled with aspect ratio on?

The system auto-calculates the other dimension based on the original ratio. If both are filled, it scales proportionally to fit within the target box.

Q: Will image quality drop after resize?

Resizing resamples pixels. Output keeps the original format with controlled quality loss.
