DNG Cleaner

Don’t let software updates erase your photography history. DNG Cleaner is the essential utility for optimizing your library and rescuing "unreadable" DNG files. Whether you are a professional archivist or a hobbyist photographer, DNG Cleaner is the smartest way to manage your Digital Negative files on macOS. We don’t just save you disk space—we now save the photos you thought were lost forever. NEW: CORRUPTED FILE RESCUE Have you discovered that DNG files created or edited with older software (such as previous versions of DxO’s image processing suite) no longer open on modern image processing software - those pesky "Unexpected end of file" messages? The Fix: DNG Cleaner now detects and repairs malformed DNG headers and compatibility issues caused by legacy converters. The Result: Make your older archives readable, editable, and future-proof again. EDITS A CONFUSED MESS? When used with products such as Adobe Lightroom or PhotoShop, DNG images can accumulate settings, previews, etc that just take up space and waste your time. DNG cleaner fixes that in a single step. DNG Cleaner also allows you to change the camera make and model, and remove cropping. RECLAIM GIGABYTES OF SPACE DNG files often contain bloated, full-size JPEG previews that take up massive amounts of space without adding quality to your RAW data. The Fix: DNG Cleaner strips away these unnecessary previews and optimizes the file structure. The Result: Reduce file sizes by megabytes per image—saving you gigabytes across your entire library—without touching the actual RAW image data.
