    Security Considerations

However, it is essential to ensure that the images being uploaded and downloaded are safe and come from trusted sources.


    The ImageResizerPlus project was developed to provide a straightforward and user-friendly interface for resizing images. Special thanks to the Bootstrap CSS framework for providing pre-styled components and making the application responsive and visually appealing.
