About K25 to TIFF Conversion
TIFF (Tagged Image File Format) is the professional standard for archival-grade image storage, supporting lossless compression, multiple color spaces, 16-bit depth, ICC color profiles, and extensive metadata. Converting Kodak K25 RAW files to TIFF produces the most technically complete archival representation of these early digital photographs, with all the metadata and color management infrastructure that professional archives, museums, and digital preservation programs require.
For institutional archives that have standardized on TIFF as their preservation format, K25-to-TIFF conversion integrates early Kodak digital photographs into existing archival workflows and storage systems. TIFF's acceptance by the Library of Congress, national archives worldwide, and museum digitization programs makes it the format of choice for permanent preservation.
Why Convert K25 to TIFF?
TIFF is the de facto standard for digital preservation in cultural heritage institutions. Libraries, museums, and archives worldwide use TIFF as their master file format because it supports lossless compression, embedded color profiles, and rich metadata — all essential for long-term preservation. Converting K25 files to TIFF aligns these early digital photographs with institutional preservation standards.
Unlike PNG, TIFF supports embedded ICC color profiles, 16-bit per channel depth, multiple pages, and IPTC/XMP metadata blocks that archival workflows depend on. For institutions that already have TIFF-based ingest, cataloging, and storage infrastructure, K25-to-TIFF conversion produces files that integrate seamlessly into existing preservation pipelines.
Common Use Cases
- Ingest Kodak DC25 photographs into institutional digital preservation systems that require TIFF
- Create archival master files meeting Library of Congress recommended format specifications
- Preserve early digital photography in TIFF for museum and library digital collections
- Generate metadata-rich archival copies of K25 files with embedded ICC profiles and IPTC data
- Integrate DC25 captures into existing TIFF-based digitization workflows at cultural heritage institutions
How It Works
The K25 file is decoded from Kodak's proprietary format, demosaiced, and color-corrected. The output is written as a TIFF file using LZW lossless compression within the TIFF container. The file includes an IFD (Image File Directory) with resolution, color space (sRGB), bits-per-sample, and photometric interpretation tags. An embedded ICC profile ensures consistent color reproduction across calibrated displays and printers. Additional metadata fields (IPTC, XMP) can be populated with source information.
Quality & Performance
TIFF with LZW compression is mathematically lossless — identical pixel values to the decoded K25 source. The format introduces zero quality degradation. At 493x373 pixels, LZW-compressed TIFF files are typically 200-400 KB, making them efficient for storage despite the lossless guarantee. The quality ceiling is the DC25's original sensor output.

Tips for Best Results
- 1Use LZW compression for the best compatibility across TIFF readers and archival systems
- 2Embed an sRGB ICC profile to ensure consistent color display across calibrated devices
- 3Populate IPTC metadata fields with camera model, approximate date, and collection information
- 4TIFF is the recommended archival format for institutional preservation — use it when integrating K25 photos into formal collections
- 5Store TIFF files alongside original K25 files for complete preservation redundancy
K25 to TIFF converts Kodak DC25 photographs into the gold-standard archival format, producing professionally structured, metadata-rich files suitable for institutional digital preservation and cultural heritage collections.
