Frequently asked questions

Will resizing distort my image?

Only if you turn off the aspect-ratio lock and use mismatched dimensions. Keep the lock on to preserve proportions.

Can I upscale a small image?

Yes, but enlarging beyond the original resolution can look soft. Resizing down always stays crisp.

Is there a file size limit?

No hard limit — because everything runs locally, only your device's memory matters.
