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.
