Why do my HDR photos look wrong?
Newer phones save photos as Ultra HDR (Android) or HDR with a gain map (iPhone). The file holds a normal picture plus a hidden second image — the gain map — that tells HDR screens how much brighter to make each part of the photo. That's great on a new phone, but many apps, websites, editors, photo printers and older screens handle it badly. Typical problems:
- The photo looks washed out, grey or too dark on another device.
- Highlights look blinding or glowing next to normal photos on social media.
- The photo looks different after editing, because the editor ignores the gain map.
- Upload forms reject the file or show odd colours.
Removing the gain map leaves the standard picture that was already inside the file. It looks the same everywhere and is usually a bit smaller.
Lossless: the same pixels, without the HDR layer
Most converters decode your photo and save it again as a new JPG, which always costs a little quality. With JPG – original quality this tool copies the original image data byte for byte and only leaves out the gain map and HDR metadata. Your date, camera and lens information are kept; the GPS location is removed unless you untick that option. Need a smaller file or another format? Choose JPG – smaller file, WebP or PNG.
Which phones take Ultra HDR photos?

- Samsung Galaxy S24 and newer, and other phones with Android 14 or later.
- OnePlus, Xiaomi, Oppo, Vivo and other recent Android phones.
- iPhone 12 and newer save HDR photos with a gain map when shared or exported as JPG.
Frequently asked questions
Does converting Ultra HDR to JPG reduce quality?
No. With the default setting the original JPEG data is kept and only the gain map and HDR metadata are removed, so the pixels are exactly the same.
Are my photos uploaded?
No. Everything happens in your browser. Your photos never leave your device, so it's safe for private pictures.
Can I convert HEIC files from my iPhone?
Not yet in most browsers. Share the photo as JPG from your iPhone (Settings → Camera → Formats → Most Compatible) and convert that file here.
How do I know if a photo is Ultra HDR?
Drop it in the converter. Photos that contained a gain map are labelled “HDR gain map removed”; normal photos are labelled “Standard JPEG”.
Can I turn off Ultra HDR on my phone?
On a Pixel, open the Camera app, go to Settings → More settings and switch off Ultra HDR. On Samsung, look under Camera settings → Advanced picture options. Photos you already took can be converted here.
