The National Archives of India prioritizes lossless and high-resolution image formats for digitization to ensure long-term preservation of historical records. TIFF is a standard for archival imaging due to its ability to store uncompressed or losslessly compressed image data, maintaining maximum fidelity. PDF is suitable for document preservation, and JPG is used where file size is a concern, though it is a lossy format. PNG, while lossless, might not always be the preferred choice for large-scale archival digitization compared to TIFF.
