Technical Quality Assessment

File size can exceed 4GB (PSD limited to 2GB) When this data is re-encoded into Nikon RAW, Optional lossless compression reduces file size by ~50% Xonvert accounts for these differences to maintain visual and structural integrity. Color accuracy is a priority in this conversion. Color profiles (sRGB, Adobe RGB, etc.) are preserved when both formats support them. The output closely matches your original. File size after conversion depends on the content complexity and your quality settings. Nikon RAW preserves all data losslessly, so output size depends on the content's inherent compressibility.

Converting between image formats is one of the most common file operations. When moving from Photoshop Big to Nikon RAW, key considerations include color depth preservation, transparency support, and compression artifacts.
