2. Can I resize multiple PNG pictures at once?
Yes, countless web-based applications and some desktop programs can resize PNG images in a bulk at once.

5. Will resizing a PNG image change its aspect ratio?
It depends on how you resize the photo. If you maintain the proportional relationship between width and height, the image's aspect ratio will remain the same. However, if you adjust the width and height independently, the aspect ratio may change, resulting in distortion.
6. Will resizing a picture affect its transparency?
All resizers should preserve any transparent areas. However, if you save the PNG in a format that does not support transparency (e.g., JPEG), such areas may be converted to solid colors.
