Frequently asked questions
What does FrameOS export?
FrameOS exports App Store-ready screenshots and preview videos at iPhone and iPad dimensions accepted by App Store Connect.
Do I need to know Apple’s exact sizes?
No. Pick the target device size in FrameOS and export. The goal is to avoid manually looking up dimensions every time you prepare store assets.
Can I trim App Store preview videos?
Yes. Import a screen recording, cut it down to the part that best shows the app, mute unwanted audio if needed, then export the preview video.
Does FrameOS crop my screenshots or videos?
You can fit media inside the output canvas to preserve the full image, or fill the canvas when you want a tighter crop.
Do my files leave my device?
No. Import, editing, and export happen locally on your device. FrameOS does not upload your screenshots, videos, audio, or exported files.
Is this a full video editor?
No. FrameOS is intentionally focused on App Store assets: sizing, framing, trimming video clips, audio cleanup, and export.
