Frequently Asked Questions
What does Maintain Aspect Ratio mean?
Aspect ratio is the proportional relationship between an image's width and height. Checking this box ensures that when you change the width, the height is adjusted automatically to keep the image from looking stretched or distorted.
Can I convert formats while resizing?
Yes. You can upload a PNG and export it as a JPEG (or vice versa) simply by changing the output format dropdown before clicking download.
Will the quality degrade when I resize?
Shrinking an image removes pixels, making it smaller and lighter. Enlarging an image past its natural resolution might make it look blurry, as the canvas has to interpolate and fill in missing pixel details.
