FAQ
What does image resize / expand mean?
It extends an image outward to a target ratio by padding the edges instead of cropping or stretching the original — useful for unifying images to one ratio, e.g. product or social media images.
Does it enlarge or blur the original?
No. The original stays untouched; only the surrounding area is added, blurred or darkened for a natural look.
Are my images uploaded to a server?
No — everything runs locally in your browser, so your images never leave your device.
