FAQ
Questions
- Is my file uploaded?
- No. The file is opened by your browser and processed on your device. Nothing is sent to us, and it is released when you load another file or leave the page.
- Why does it take as long as the video?
- Your browser plays the video once while it records the new file, so a 30 second clip takes about 30 seconds. Keep the page open until it finishes. Videos up to 3 minutes work.
- Which file do I get?
- An MP4 in Safari and in recent Chrome and Edge. Firefox and older Chrome save WebM, which plays in browsers, VLC and most editors. The page says which one you will get before you start.
