Frequently asked questions
Will resizing distort my image?+
Not if you keep the aspect ratio locked. Unlock it only when you intentionally want to stretch the image.
Can I make an image larger?+
Yes, but enlarging beyond the original size can look soft because no new detail can be added.
Is my image uploaded?+
No. Resizing happens entirely in your browser.
