Transparency is lost in JPG files, as they do not support transparent backgrounds. However, PNG files do support transparency, allowing for images to have transparent backgrounds. When saving an image with transparency as a JPG file, the transparent areas will be filled with a solid color, resulting in the loss of transparency. Therefore, if transparency is important for an image, it is best to save it as a PNG file. **

Disk optimization is the process of reorganizing the data on a computer's hard drive to improve its performance and efficiency. This can involve tasks such as defragmenting the disk, which rearranges fragmented data so that it is stored in contiguous blocks, or running disk cleanup to remove unnecessary files. Disk optimization does not delete all your files; it simply reorganizes and cleans up the existing data on the disk to improve its overall performance. However, it is always a good idea to back up your important files before performing any disk optimization, just to be safe. **
