Frequently asked questions
Will resizing distort my image?
Not if 'maintain aspect ratio' stays checked — it keeps width and height proportional.
Can I make an image larger?
Yes, up to 200% with the slider, though enlarging beyond the original size can soften detail.
What format is the output?
PNG, to preserve quality regardless of the source format.
