Questions
Does Video Transformer upload my video?
No. Videos are transformed locally in your browser tab and are never uploaded to Utilumo.
Can I keep the original aspect ratio?
Yes. Leave either width or height at 0 and the export keeps the source aspect ratio for that missing dimension.
Does rotation change the file itself?
The original file is never changed. The tool creates a new MP4 with the selected rotation baked into the export.
Does Utilumo upload my input?
No. This tool is designed for local browser processing and does not send your input to a server.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
