FAQ
Frequently asked questions
Are my files uploaded?
No. The conversion runs inside your browser using WebAssembly, so your files never leave your device. Nothing is sent to our servers.
How big can my audio files be?
Up to 200 MB each on the free plan and 2 GB with Pro. Very large files depend on your device's memory.
Why is the first conversion slower?
The first time, your browser downloads the converter (a few MB). It's cached, so later conversions start right away. Where your browser supports it, video uses your device's hardware encoder.
