Your JP2 file is decoded — the compressed/stored pixel data is expanded into raw RGBA (with alpha channel) pixels
Pixels are re-encoded using Adobe Photoshop Document's lossless compression
Metadata (EXIF, ICC profiles) is transferred where PSD supports it
The PSD file is saved and ready for download
