Frequently Asked Questions
Can I resize without distorting the image?
Yes - lock the aspect ratio toggle keeps width and height proportional automatically as you change one value.
Does resizing to a larger size improve image quality?
No - enlarging a smaller image can only stretch existing pixel data, so it may look softer; for genuinely higher resolution you need a larger source image to begin with.
What image formats can I resize?
Common formats like JPG, PNG, and WebP are supported for both input and output.
