  • Q: Can I resize multiple images simultaneously?
    • A: Currently, the tool supports resizing one image at a time. However, users can resize multiple images sequentially by uploading each image individually.
  • Q: Are there limitations on the file size or image dimensions?
    • A: The tool may have limitations imposed by the user’s web browser or device regarding file size and image dimensions. Large images or excessively high-resolution images may consume significant system resources and processing time during resizing.
  • Q: Can I resize images with different aspect ratios?
    • A: Yes, the tool allows users to specify both the width and height independently, enabling resizing images with different aspect ratios. However, users should be aware that resizing an image with a different aspect ratio may result in stretching or distortion of the image.
