Frequently Asked Questions
What is the difference between Crop and Letterbox?
Crop removes excess parts of the image to fit the chosen ratio, cropping from the center. Letterbox adds colored padding to fill the ratio without losing any part of the original image.
Is image quality maintained?
Resizing is done using the browser's Canvas API. Output is PNG format for maximum quality.
