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 RAW images to HEIC applies essential post‑processing: white balance, demosaicing, and tone mapping. The result is a standard image ready for printing or further editing in any software. convert.dynamic_reason_closing.closing_12

Lossy compression introduces minor quality loss — set quality to 90%+ to minimize
