Q: What if image quality drops significantly after compression?
A: Try increasing the compression quality settings, or check if the original image has already been compressed. Some image formats have inherently high compression rates.
Q: Why is the compression effect not obvious for some images?
A: If the original image has already been optimized or the file is small, there is limited compression space. It's recommended to check the format and size of the original image.
Q: What image formats are supported?
A: Supports common formats such as JPG, PNG, WebP, GIF, BMP, etc. Output format can be selected according to needs.
