PNG is the ideal lossless archival target for Kodak K25 files. Converting K25 to PNG preserves every pixel of the decoded DC25 sensor data without any compression artifacts while producing compact files thanks to PNG's DEFLATE lossless compression. At the DC25's 493x373 resolution, PNG files are typically 150-300 KB — substantially smaller than uncompressed BMP while maintaining mathematically identical pixel values.

For anyone serious about preserving Kodak DC25 photographs, PNG is the recommended format. It combines lossless quality with broad universal support, small file sizes at this resolution, and embedded metadata capabilities. Every operating system, web browser, and image editor in existence supports PNG natively.

PNG offers the best balance of quality and practicality for K25 archival. Unlike JPEG, PNG preserves every pixel without compression artifacts. Unlike BMP, PNG applies lossless compression that reduces file sizes significantly. Unlike TIFF, PNG is natively supported by all web browsers, making images immediately shareable online. For the DC25's modest resolution, PNG files are so small that there is no practical reason to use a lossy format.

PNG also supports embedded text chunks for metadata, alpha transparency, and gamma correction — features that make it future-proof as an archival format. The format is an open standard maintained by the W3C with no patent encumbrances, ensuring permanent accessibility.

The K25 RAW data is decoded from the Kodak proprietary format, demosaiced from the DC25's Bayer CCD sensor pattern, and color-corrected. The full-color 24-bit RGB image is then compressed using PNG's DEFLATE algorithm, which achieves lossless compression by exploiting spatial redundancy in the pixel data. The output includes an sRGB color space declaration and any available metadata in PNG text chunks. At 493x373 pixels, compression ratios are highly favorable, producing files of 150-300 KB.

Yes. PNG is lossless while JPEG introduces compression artifacts. At the DC25's tiny resolution, the file size difference is negligible (150 KB PNG vs 30 KB JPEG), so there is no practical advantage to using lossy JPEG.

Both are lossless, but PNG files are smaller (DEFLATE vs uncompressed or LZW TIFF) and natively supported by web browsers. For DC25-resolution images, PNG is the more practical lossless choice.

Yes. Every photo editor — from Photoshop and GIMP to Apple Photos and Windows Photos — opens and edits PNG files natively.

Roughly 3,000-6,000 depending on image complexity. The DC25's low resolution keeps PNG files very small at 150-300 KB each.

Available metadata is stored in PNG text chunks. K25 files have limited metadata compared to modern cameras, so the information transferred depends on what the DC25 recorded.
