Why convert DNG to HEIC?

Introduced in 2004 by Adobe, DNG was great for its time. But HEIC (created in 2017 by Apple / MPEG) offers lossy compression and 10-bit HDR – a massive leap forward. Converting DNG to HEIC extracts the small JPEG preview the camera embedded in the RAW file — it does not perform a full RAW decode (demosaicing, white balance, tone mapping) on the sensor data. The result is a quick, preview-quality image; for full-resolution processing, use dedicated RAW software like Adobe Camera Raw or Lightroom. This kind of format decision tends to matter more as a project scales up.

JPEG compression introduces minor quality loss — set quality to 90%+ to minimize
RAW conversion may take longer — files are processed via WebAssembly in your browser

Frequently Asked Questions

Typically 60-90% smaller for lossy HEIC, or 20-40% for lossless HEIC compared to uncompressed DNG.
HEIC has limited native browser support, so it's best used for storage/processing rather than direct web display. Check caniuse.com for the latest status.
DNG is not an animation format, so this conversion always processes static images — no animation handling needed.
Yes — HEIC fully supports transparent areas, so they are preserved exactly as in the original.
