Questions, answered.
Can I resize a video without uploading it?
Yes. Resizing happens in this tab. Your file stays on your device. Sign in to your free Sentarys account to resize and download.
Which formats can I export?
Choose 9:16 at 720×1280, 1:1 at 1080×1080, 4:5 at 864×1080 or 16:9 at 1280×720. Every export is an H.264 MP4 with audio.
Can I keep the full frame?
Yes. Use a blurred copy of your video or a black background to fill the space. Crop to fill lets you move the focus horizontally and vertically.
How large can my file be?
Choose a video up to 256 MB. Preview the frame before export and keep this tab open while it works.
