Make your Instagram posts glow
Instagram displays true HDR photos — but your camera roll exports are usually SDR. Convert before you post and your photo lights up against everyone else's feed. Posting Reels? You can convert video to HDR, too.

Still perfect on old screens
HDR photos degrade gracefully: viewers without HDR displays see your normal photo, nothing broken.
