FAQ

Will resizing distort my image?

Not if aspect ratio is locked. Unlocking it lets you set any width and height, which can stretch the image.

Can I make an image bigger than its original size?

Yes, though enlarging an image beyond its original resolution can make it look softer or less sharp.

Is my image uploaded anywhere?

No. Resizing happens entirely in your browser.
