Frequently Asked Questions (FAQ)
What is the Aspect Ratio Lock?
The lock icon maintains proportions so that when you adjust width, height scales automatically to prevent distortion or stretching.
Are my photos saved on any server?
No. Your images are drawn and resized locally on your device via HTML5 Canvas. They never leave your device.
