Camera EXIF (ISO, shutter, lens, GPS coords) is preserved by default during PNG → PSD when both formats support metadata. Use the privacy option to strip metadata before download if you need to share images without geolocation.
For JPG / WebP, quality 75-85 typically gets the PSD 60-80% smaller than PNG with no visible difference at normal viewing distance. For lossless PSD (PNG, TIFF), expect smaller savings — usually 5-30% via better deflate / LZW compression. 私营部门司保持每项编辑决定可逆性,因此,设计工作的主格式将加以修订。
