Why Aspect Ratio Locking Matters

When aspect ratio is locked, changing the width automatically updates the height proportionally. This prevents your photos from appearing awkwardly stretched or squashed. You can uncheck "Lock Aspect Ratio" if you intentionally need to force exact non-proportional dimensions.

Memory Safety Guards

To prevent browser crashes, dimensions are bounded between 10px and 6,000px. This guarantees smooth execution and ensures your browser tab will not run out of memory when generating high-res canvases.
