Frequently asked questions
How does it work?
Upload a screen recording or iOS simulator video, choose Fit or Fill, and export an App Store-ready MP4. The preview updates before processing so you can see how the video will fit.
Is my video uploaded permanently?
No. Videos are stored temporarily while processing and are automatically deleted shortly afterwards.
Does it work with portrait and landscape videos?
✅ Yes. The tool detects the video orientation and shows the matching preview shape before export.
What is the difference between Fit and Fill?
Fit keeps the whole video visible and adds padding if needed. Fill uses the full App Store preview frame and crops the edges if the video does not match the target shape.
What size does it export?
Portrait videos are exported at 886 × 1920 pixels. Landscape videos are exported at 1920 × 886 pixels.
Does it keep audio?
If your original video has audio, the exported video keeps it. If it does not, the tool adds a silent audio track so the file is more likely to be accepted by App Store Connect.
What format does it export?
The exported video is optimised for App Store previews. It uses H.264 video, AAC audio, a frame rate of 30 FPS and the correct preview dimensions for portrait or landscape videos, so in most cases it can be uploaded directly to App Store Connect.
