Fit or crop
Keep the full frame or fill the vertical canvas.
Publish after export
Download MP4 and use it in Upnext.
Fit a video into the format you need
Choose Fit to keep the complete source frame with padding, or Fill & crop to remove the edges and fill the destination. Review faces, subtitles and important action before exporting.
The converter exports MP4 in vertical, portrait, square or landscape presets. It changes the canvas and encoding; it does not add music, captions or a publishing schedule.
Convert locally when you are ready
The conversion engine downloads only when you start a conversion. The first run needs about 31 MB of additional download, and video processing can use substantial memory. Your video is processed in the browser rather than uploaded for conversion.
Keep the tab open, start with a short clip and use Cancel if needed. Large or complex files may exceed your device’s capacity. Check the exported file against Upnext’s composer requirements before scheduling it.
