Frequently asked questions
Are my images uploaded anywhere?
No. Resizing happens locally in your browser using the canvas API, so your images never leave your device.
Will locking the aspect ratio prevent stretching?
Yes. With aspect ratio locked, changing width auto-adjusts height (and vice versa) so the image keeps its proportions and never looks squashed.
