DNG Resizer

The DNG Resizer processes Digital Negative RAW files by resizing to user-specified target dimensions or by applying a scale factor. It accepts single files or batches and outputs new DNGs with the requested size. The tool preserves the original color space, bit depth, and metadata, ensuring RAW integrity for photographers and editors.
It uses a high-quality resampling algorithm to interpolate pixel values, with optional cropping to enforce a target aspect ratio. If both width and height are provided, the resulting image fits within those bounds; if only one dimension is supplied, the other is derived from the source aspect ratio. Batch processing applies consistently across all inputs.
Outputs include the resized DNG files in a designated output directory, along with a brief per-file summary (dimensions, estimated size). The tool operates offline or in serverless mode depending on deployment; outputs retain the DNG container and original metadata unless conversion is requested.
Professional studios, freelancers, and archival projects benefit from metadata-preserving, batch-capable resizing that yields reproducible results. Its differentiators include strict metadata preservation, configurable cropping and aspect-ratio behavior, and per-file output tracking for large asset sets.
