Questions
Good to know.
Is my file uploaded?
No. It is converted in this tab with your browser, so the file never leaves your computer.
What is a AV1 file?
AV1 is a newer open video format used by YouTube, Netflix and some screen recorders. Many older devices and editors cannot play it.
Why convert to MP4?
MP4 is the most widely accepted video format: phones, editors, YouTube and most websites take it.
Does it lower the quality?
The picture is re-encoded as H.264, so there is a small loss, as with any re-encode, and the file is often larger than the AV1.
Does my browser need to play AV1?
Yes, to read it. Current Chrome, Edge and Firefox play AV1, and Safari does on newer Apple chips.
Is there a size limit?
The file is handled in your browser's memory, so very large files can fail. Close other tabs and try again.
Which browsers work?
Current Chrome, Edge and Safari, which can encode H.264 video, as long as they can also play the original.
