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, with a WebM fallback on some browsers. It glows on HDR screens and plays as normal video everywhere else.
Frequently asked questions
Chrome and Edge on the desktop, and Chrome on Android. Safari and iPhone can't create HDR video in a browser yet — use the MakeHDR app on your iPhone or iPad, or convert on a computer with Chrome or Edge.
No. The entire conversion runs in your browser; your clip never leaves your device.
In the browser, up to 4K (3840px on the long edge). For full 4K, long clips and the fastest encode, the MakeHDR app has no cap.
A BT.2020 HDR video. From the browser it's HEVC 8-bit in an MP4 that plays in Chrome, Safari, QuickTime and iPhone Photos, with a VP9 WebM fallback on browsers that can't encode HEVC. The MakeHDR app exports HEVC 10-bit, PQ or HLG.
No. MakeHDR computes the HDR from your clip's own light with a deterministic gain curve — no generation, no upscaling, no altered footage.
