App Preview Video Specs for App Store and Google Play (2026)
Verified againstApple app preview specifications,Google Play asset specificationson 2026-08-15.
An App Store app preview is a 15 to 30 second video, H.264 or ProRes, at the device screenshot resolution, up to 3 per localization, captured to look like real on-device use. Google Play is different: the promo video is a YouTube URL, not an uploaded file, with 30 seconds to 2 minutes recommended. Where a number is version-sensitive, verify it in App Store Connect.

App Store app previews
App previews play directly in the App Store listing. Keep each one between 15 and 30 seconds, export as H.264 or ProRes, and match the resolution to the device display class you are targeting in portrait or landscape. You can supply up to 3 previews per localization. Apple expects the footage to look captured on-device and to show the app actually being used. Because accepted resolutions shift as new devices ship, verify the exact pixel dimensions in App Store Connect at upload time.
Google Play promo video
Google Play does not host your video. You add a YouTube link to the store listing and Google embeds the player. There is no file upload and no App Store style hard limit, though 30 seconds to 2 minutes is the common recommendation. Keep the video public or unlisted, keep it focused on the app, and avoid ads or promotional overlays. Because the video is on YouTube, its resolution and codec follow YouTube's requirements rather than a Play-specific spec.

Frequently asked questions
How long can an App Store app preview be?
15 to 30 seconds. App Store Connect rejects previews shorter than 15 seconds or longer than 30. Plan the edit around that window and lead with the core value in the first few seconds.
What video format does the App Store require?
H.264 or Apple ProRes. The preview resolution matches the device screenshot size for the display class you are targeting, in portrait or landscape. Because the accepted resolutions are version-sensitive, confirm the exact pixel dimensions in App Store Connect when you upload.
How many app previews can I upload?
Up to 3 app previews per localization on the App Store. Each preview is tied to a device display class, so a portrait iPhone preview and an iPad preview are separate assets.
How is the Google Play promo video different?
Google Play does not host the video. You paste a YouTube URL into the store listing and Google embeds it. There is no uploaded file, no App Store style length limit, and the practical recommendation is roughly 30 seconds to 2 minutes. Keep the video public or unlisted so Google can display it, and do not include ads.
Do I need a video at all?
No. Both stores treat the video as optional. Screenshots are the required asset. A preview or promo video is an enhancement that tends to lift conversion, but a listing publishes fine without one.
