FAQ

  • Q: What color will the background of the converted image be? A: Since the JPG format does not support transparency, transparent areas in the original PNG will automatically be filled with white after conversion.
  • Q: Is there a limit to the number of images I can convert with NekoLabTools? A: This tool has no strict file quantity limit; processing speed and capacity primarily depend on your device’s memory performance.
  • Q: Why did the converted JPG file size increase instead? A: If the original PNG image has very simple colors and is set to 100% quality, JPG’s encoding characteristics might lead to an increased file size. It is recommended to reduce the quality appropriately.
