Why Convert DNG to HEIF?
DNG (Digital Negative) is Adobe's open-source RAW image format used by many cameras and smartphones (including Google Pixel and some Samsung devices) as an alternative to proprietary RAW formats. DNG files contain unprocessed sensor data at 12–16 bit color depth, giving photographers full control over exposure, white balance, and color grading.
HEIF (High Efficiency Image Format) uses HEVC compression to produce images that are roughly 50% smaller than JPEG at the same visual quality. It supports 10-bit color depth, transparency, and image sequences. HEIF is the default photo format on iPhones (iOS 11+) and is increasingly supported on Android and Windows.
Converting DNG to HEIF is useful when you want to reduce file size dramatically while retaining higher color depth than JPEG. A 25 MB DNG file can become a 2–4 MB HEIF with excellent visual quality — ideal for sharing or archiving large photo libraries.

Frequently Asked Questions
Will converting DNG to HEIF lose quality?
DNG is a RAW format with 12–16 bit color depth, while HEIF uses lossy HEVC compression at 8–10 bit. Some data is inherently lost. However, HEIF retains significantly more quality than JPEG at the same file size. For archival purposes, keep your original DNG files and convert copies to HEIF for sharing.
Can I open HEIF files on Windows?
Yes. Windows 10 and later support HEIF natively with the free "HEIF Image Extensions" from the Microsoft Store. Older Windows versions require third-party viewers like IrfanView or CopyTrans HEIC.
Is HEIF the same as HEIC?
Nearly. HEIC is Apple's specific implementation of the HEIF standard, using HEVC compression. HEIF is the broader standard that can use different codecs. In practice, HEIC and HEIF files are interchangeable on most devices. See our DNG to HEIC converter if you specifically need the .heic extension.
Can I batch convert an entire DNG photo library?
Yes. Upload multiple DNG files and they will all be converted to HEIF with the same quality settings. Download them individually or as a ZIP archive.
