Filmed something with HDR on and now it looks washed out everywhere except your phone? Drop the video on this page. It gets tone-mapped to standard colors and re-encoded to H.264 with your hardware encoder, audio untouched, and the result plays correctly in every editor, every app, and on every screen. Free, no size caps, and the video is never uploaded anywhere.
Why HDR video betrays creators
iPhones record HLG or Dolby Vision, Androids record HDR10 or HLG, and on the phone that shot it, the footage looks incredible. Then you drop it into an editor or an app that works in standard colors, and everything falls apart: the frame goes flat and gray, text and graphics you add live in a different brightness world than the video behind them, and the exported result looks different on every device your audience owns. Editors and platforms each tone-map however they feel like it. The only way to get one consistent result is to hand them SDR footage in the first place, and phones don't offer a convert-existing-video button. This page is that button.
What actually happens to your video
Every frame is decoded, tone-mapped down to standard colors (the same rendering a non-HDR screen would show), and re-encoded to H.264, the codec everything on earth plays. Your audio track is carried across untouched. Because this is a real re-encode of every frame, a long video takes a few minutes; your hardware encoder does the heavy lifting, and nothing waits in an upload queue first.
| Input | Output |
|---|---|
| iPhone HDR (HLG / Dolby Vision) MOV or MP4 | Standard SDR H.264 MP4 |
| Android HDR10 / HLG video | Standard SDR H.264 MP4 |
| Already-SDR video | Converted anyway, with a note saying it looked SDR already |
FAQ
Does the quality drop?
The brightness range is deliberately reduced (that's the point: HDR highlights get mapped into the standard range), and the re-encode runs at high bitrate, so the result stays crisp. What you lose is the glow on an HDR screen; what you gain is footage that looks right on every screen.
Is the audio kept?
Yes. The original audio track is copied across without re-encoding whenever the format allows, which covers virtually all phone footage.
Why is it slower than the photo tool?
The photo version does byte surgery with no re-encode. Video has no such shortcut: every frame gets tone-mapped and re-encoded. Your hardware encoder keeps it quick; a phone clip usually finishes in well under a minute on a computer.
Which browser works best?
Chrome or Edge on a computer. Phone-recorded HDR is usually HEVC, and those browsers decode it with your machine's hardware. If your browser can't decode the codec, the tool says so plainly instead of producing a broken file.
Is my video uploaded?
Never. A 2 GB video would take ages to upload anywhere; skipping the upload is both the privacy and the speed. Your footage is never uploaded, stored, or seen by anyone. Here's how to check.
