How it works
Make an App Store preview in three steps
Turn a screen recording into a preview App Store Connect accepts on the first try.
Pick the device size
See every App Store rule your video passes or fails, choose the 15 to 30 seconds to use, and preview the exact frame.
Export and upload
Download an MP4 that is verified against Apple's rules, then drop it into App Store Connect.
Why App Store Connect rejects app previews.
App previews have strict technical rules, and a screen recording straight off an iPhone breaks most of them. It's the wrong resolution (1179×2556 instead of 886×1920), often 60 fps, usually HEVC, and has no audio track if the microphone was off. This tool fixes all of that in one export.
The exact sizes
Every current iPhone uses 886×1920 (portrait) or 1920×886 (landscape). The 5.5-inch iPhone uses 1080×1920, the 4.7-inch 750×1334, and iPads 1200×1600. Upload the largest size you support and Apple scales it for the rest.
Length and frame rate
Previews must run 15 to 30 seconds at no more than 30 frames per second. Exports here are a constant 30 fps, H.264 at Apple's recommended 10 to 12 Mbps, and 500 MB is never close.
Audio is expected
Apple wants a stereo AAC track, even for silent previews. Recordings without sound get a silent stereo track, so the upload isn't rejected for missing audio.
What about Google Play?
Google Play doesn't take video uploads. It uses a YouTube link instead. Upload the same recording to YouTube as a public or unlisted video, landscape works best, and paste the URL into Play Console.
FAQ
App Store preview questions
What resolution is an App Store app preview?
886×1920 portrait or 1920×886 landscape for every iPhone with Face ID or Dynamic Island. 1080×1920 for 5.5-inch iPhones, 750×1334 for 4.7-inch iPhones, 1200×1600 for most iPads, and 1920×1080 for Mac and Apple TV.
How long can an app preview be?
Between 15 and 30 seconds. You can upload up to three previews per device size and language.
Why was my app preview rejected?
The usual causes are the wrong resolution, a frame rate above 30 fps, a length outside 15 to 30 seconds, HEVC video, or a missing audio track. This tool checks and fixes all of them.
Is my video uploaded to a server?
No. Everything runs in your browser on your own device. Your recording never leaves your device.
Can I use this for Google Play?
Google Play uses a YouTube link rather than an uploaded video, so there are no file rules to meet. Upload your recording to YouTube and add the link in Play Console.
