Questions
Why does the first conversion take longer?
The converter (about 30 MB) downloads the first time you use it. After that your browser keeps it, so later conversions start right away.
Is my video uploaded?
No. The audio is extracted inside your browser, so your video never leaves your device.
How long does it take?
It depends on your device. On a laptop, a one-hour lecture usually takes a few minutes. Phones are slower, and very large videos (over 1 GB) may not fit in a phone's memory.
Which quality should I pick?
Smaller file (128 kbps) is fine for speech and saves space. Standard (192 kbps) suits most things. Best (320 kbps) is for music, where you'll notice the difference.
