How to convert a video to HDR
You can turn an ordinary SDR clip into true HDR video right in your browser — no editing skills, no AI. On an HDR screen the bright parts physically glow. Here's exactly how.

1
Open MakeHDR and drop your video
Open the converter in Chrome, Edge or an Android browser and drag in your clip. It's processed on your device — nothing uploads.
2
Pick your HDR strength
Choose Subtle, Balanced or Maximum. MakeHDR applies a real HDR gain curve to your video's own light — no AI, no invented detail.
3
Download your HDR video
Save your HDR video — an MP4 that plays in Chrome, Safari, QuickTime and iPhone Photos. It glows on HDR screens and plays as normal video everywhere else.
No AI and nothing uploaded: the HDR is computed on your device, from your own pixels.
Frequently asked questions

No. MakeHDR computes the HDR from your clip's own light with a deterministic gain curve — no generation, no upscaling, no altered footage.
Use the MakeHDR app for iPhone and iPad: pick a clip from Photos, choose a strength (Balanced is the default) and share the result — a 10-bit HEVC HDR video that plays as HDR in Photos and posts as an HDR Reel. It's free to try with a watermark.
