LumaFlow: HDR to SDR converter
Photo & Video
Free · In‑App Purchases
LumaFlow turns HDR video into clean, editor-ready SDR — without washed-out highlights or color shifts.
If you've ever dropped an iPhone HDR clip into Premiere, Final Cut, or CapCut and watched the highlights bloom into a
milky mess, you know the problem. Modern phones record HDR by default. Most editors don't handle it well. The "fix"
usually means a detour through DaVinci Resolve and a half hour of color science you didn't sign up for.
LumaFlow does the conversion for you, the right way. Drop in your clip, wait a few seconds, and get a Rec.709 SDR file
that drops straight into any timeline. Highlights hold. Skin tones look right. Colors stay where you remember them.
WHO IT'S FOR
• YouTubers and video editors fighting iPhone HDR footage
• Creators who use Premiere, Final Cut, DaVinci, CapCut, or any non-HDR timeline
• Anyone tired of explaining "why does my footage look blown out"
HOW IT WORKS
1. Drag your HDR clips into the app.
2. Click Convert. LumaFlow uses Apple's hardware video pipeline plus a tuned tone-mapping curve.
3. Get clean SDR files saved next to the source, or wherever you choose.
WHAT YOU GET
• Real HDR-to-SDR tone mapping (not a flat exposure cut)
• Highlight detail preserved — no clipping, no haze
• Accurate Rec.709 color, ready for any editor
• Side-by-side Before/After preview
• Batch convert entire folders
• Works offline. No uploads. No account.
FREE & PRO
LumaFlow is free for 5 conversions per month. Convert as much as you want with Pro Monthly or Lifetime — a one-time
purchase that unlocks everything forever.
