💡 Big file — quick recommendation

        
  

        
This file is over 2 GB — too large for a browser to load. But here's the thing: we only need the audio. On a 4K video, the picture is mostly wasted bytes for us.

        

          
RecommendedUpload audio-only — .mp3 / .m4a

          
OrExport a smaller / compressed version

          
WhyThe audio is a tiny fraction of the size
