Local Processing

Your video is processed in your browser on your own device. The original file is not uploaded to a backend server.

Large videos can take several minutes and may make the page feel busy while the file is being converted.

Requirements

Browser Notes

This tool is designed to run from the Tool Buffalo website.

For best results, use a modern desktop browser and start with smaller files when testing a new conversion workflow.
