Troubleshooting — When Conversion Fails

Conversion is very slow or stuck
This tool uses your device's processor. Large files (above 500MB) will take time on mobile. Use Chrome on desktop for best speed. Close other browser tabs to free up RAM.

Output audio has no sound or is silent
The original video may not have an audio track (screen recordings, animated slideshows). Check in VLC player if the video has audio before converting.

File format not supported
Most common formats (MP4, MKV, AVI, WEBM, MOV) are supported. Rare formats like TS, RMVB may not work. Try converting the video to MP4 first using VLC on your PC.

Downloaded MP3 won't play on my phone
Android and iPhone both support MP3. If the file won't play, try a different player app like VLC or MX Player. Also check if the download completed fully — a partial download won't play.

Does it work on mobile?

Will the audio quality be good?
