SDR Ready: HDR Video Converter
Fix washed-out videos & photos
$6.99 · Designed for iPad. Not verified for macOS.
iPhone HDR videos and photos turn gray on Windows, Discord, WhatsApp and older TVs. SDR Ready fixes them in one tap - on your phone, no upload, no subscription.
Your iPhone videos look stunning on your phone - and washed-out gray on Windows, Discord, WhatsApp, Instagram and older TVs. That's because iPhone records HDR video, and most screens and apps outside Apple's world don't understand it.
SDR Ready fixes it in one tap. And since 2.0, it fixes washed-out HDR photos too.
Pick your videos and photos, see the before/after proof, convert. Converted copies are saved to Photos right next to the originals - originals never touched.
WHERE YOUR VIDEOS LOOK RIGHT AGAIN
• Windows and PC - Media Player, Explorer, PowerPoint
• Discord, WhatsApp, Telegram, Slack, Teams, Zoom
• Instagram, Facebook, TikTok uploads
• Older TVs, projectors, smart TVs, car screens
WHY SDR READY
• One button. No color-science quiz, no seven presets.
• Split-screen proof - see exactly what others see, before you convert.
• Batch convert. Queue as many clips and photos as you like.
• Works with everything iPhone shoots: Dolby Vision, HLG, HDR10, 4K, 60 fps.
• HDR photos (HEIC) become JPEGs that open everywhere.
• Output sizes that fit Discord (10 MB) and email (25 MB) limits.
• Already-SDR clips are detected and skipped - no pointless conversions.
• Keeps converting when you leave the app (iOS 26).
• Shortcuts action - convert from the share sheet or automate it.
• Native on iPad. In English, German, Spanish, French, Japanese, Portuguese.
• 100% on-device. No account, no upload, no internet needed.
• No subscription. Pay once, keep it forever.
WHO IT'S FOR
• Gamers and streamers sharing clips to Discord
• Families sending videos to relatives on Windows
• Creators handing footage to an editor on a PC
• Teachers and presenters showing videos on a projector
WHAT IT DOES, HONESTLY
SDR Ready converts HDR video to standard MP4 (H.264 / Rec.709) using Apple's own video engine - the same tone mapping Photos uses when it shows HDR footage on an SDR screen. Your converted copy looks right on every screen.
PRIVATE BY DESIGN
Zero network requests. No analytics, no tracking, no ads, no third-party SDKs. Your videos never leave your phone.
