QUALITY GUIDE
Choose settings for the destination.
MP3 or AAC
Use 256–320 kbps for high-quality sharing. Smaller voice files may use a lower bitrate and mono audio.
Opus or OGG
Efficient formats can produce smaller files, but confirm that the intended platform and listener device accept them.
Privacy, limits, and responsible use
The selected audio or video file and converted output remain in browser memory and are not uploaded to Blindbandit Records. When you begin conversion, the browser downloads the FFmpeg WebAssembly engine from jsDelivr. That provider receives ordinary connection information but does not receive your media file from this tool. The page now shows separate engine-download and conversion progress. Conversion speed depends on file duration, format, device memory, and processor performance. Keep the page open until the download is ready.
Only convert material you own or are authorized to process. This utility does not remove copyright protection, watermarks, access controls, or platform restrictions. Review the privacy policy, copyright policy, and website terms.
