One tap turns washed out iPhone HDR into clean SDR that looks right in any editor. Now shrink file size and change format too. All offline. Free to try. Shot in HDR on your iPhone, but the footage looks washed out, grey, or oversaturated the moment you drop it into an editor? LumaFlow fixes that in one tap. LumaFlow converts iPhone HDR video (HLG / Dolby Vision) into clean, standard SDR (Rec.709) that looks right everywhere: Premiere, Final Cut, DaVinci Resolve, CapCut, YouTube, or any timeline. Highlights hold, skin tones stay natural, and colors look the way you saw them. And now it does more than tone mapping: HDR to SDR. One tap conversion any editor understands. Compress. Shrink clips to a target size, percentage, or quality, or cap the resolution. Convert format. Switch between MP4, MOV, and M4V. Batch everything. Fix, compress, and convert multiple clips at once, and chain steps in a single pass. Why LumaFlow: Fast processing, right on your device. No uploads, no waiting. Works completely offline. Your videos never leave your iPhone. Dead simple. Drop clips, tap, save to Photos. Keeps quality intact. Never inflates or bloats your files. Perfect for editors, creators, and anyone who needs iPhone video that just works in their tools. Free to try. Upgrade to Pro for unlimited conversions: monthly, annual, or a single Lifetime purchase. One purchase works across iPhone, iPad, and Mac. Questions or feedback? We'd love to hear from you. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Almost exactly what I was looking for.

Wanted an easy, quick way to convert down to SDR as the HDR support of my monitors just isn’t quite there. This does the job. Only used on Mac so far. Couple of bugs but they don’t affect the output. Doesn’t alter the source file, but it does change the encodings of output files, so I’d prefer some choice there. Soon as it reprocesses, it resizes the window and shrinks the preview. File list is huge compared to the preview which could benefit from side-by-side comparison views. It’s a little too automatic. I’d like to see just a few extra controls for adjusting the final output and I’d prefer to apply that before processing but it’s nice that multiple adjustments don’t cost extra instances. Doesn’t reliably freeze on the frame I want to base edits on though and then you have to wait for it to process again before seeing the result so it wastes some time. Overall it serves the purpose, it could just do with some interface tweaks for a better layout and UI element spacing.

Now compress and convert, built in. Shrink clips to a target size, percentage, or quality. Change format between MP4, MOV, and M4V. Fix, compress, and convert several clips in one pass. Plus faster importing when you add lots of clips, and the same one tap HDR to SDR conversion you already rely on.
