Frequently asked questions
Can I resize without distorting the image?
Yes — turn on "Maintain aspect ratio" and the tool will calculate the matching height or width automatically.
What happens if I enlarge a small image?
You can scale up, but very small source images will look softer when enlarged since no extra detail is created.
