Convert PCD to DNG

Understanding PCD and DNG file formats

PCD (Photo CD Image) is a raster image file format developed by Kodak for storing high-quality photographic images on CDs. It was widely used in the 1990s for archiving and distributing scanned photographs. DNG (Digital Negative) is an open, lossless raw image format developed by Adobe, designed for digital photography and archiving raw image data from cameras.

Why convert PCD to DNG?

Converting PCD files to DNG allows you to preserve your scanned images in a modern, widely supported raw format. DNG files are compatible with most photo editing and archiving software, ensuring long-term accessibility and better editing capabilities.

How to convert PCD to DNG

Direct conversion from PCD to DNG is not natively supported by most software. The process typically involves two steps:

1. Convert PCD to TIFF or another common format: Use a program like IrfanView or XnView MP to open your PCD file and save it as a TIFF file.
2. Convert TIFF to DNG: Use Adobe DNG Converter to convert the TIFF file to DNG format.

Recommended software for conversion

• IrfanView (Windows): Open your PCD file, then use File → Save As and select TIFF as the output format.
• XnView MP (Windows, macOS, Linux): Open the PCD file, then use File → Export and choose TIFF.
• Adobe DNG Converter (Windows, macOS): After obtaining a TIFF, use this tool to convert it to DNG.

Step-by-step conversion process

1. Open your PCD file in IrfanView or XnView MP.
2. Export or save the image as a TIFF file.
3. Launch Adobe DNG Converter.
4. Select the TIFF file and convert it to DNG.

Tips for best results

• Always use the highest resolution available when exporting from PCD.
• Check the color profile and bit depth to preserve image quality.
• Keep backups of your original PCD files for archival purposes.
