Significantly smaller files.
DNG is a lossless format that prioritizes fidelity over size. Converting to JPG introduces modern compression that typically reduces file size by an order of magnitude with no perceptible difference at normal playback or viewing.
WHY CONVERT
01
DNG is a lossless format that prioritizes fidelity over size. Converting to JPG introduces modern compression that typically reduces file size by an order of magnitude with no perceptible difference at normal playback or viewing.
02
JPG is accepted by a wider range of image viewers, editors, and content systems than DNG. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
JPG files are typically smaller than their DNG counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.
