JPEG does not support saving transparent colors. When a PNG file with a transparent background is converted to JPEG, the background is converted to white.
Also, the image quality may deteriorate after conversion. Please be careful.

When saving to the iPhone or iPad photo folder, the file name cannot be assigned freely and is automatically assigned. Please note.
Also, when saving multiple selected photos to the cloud, create a new folder and save it with the same name as the original file. The folder name is "convert_date_time". It takes time to upload a large number of files, so please convert them several times.
