Media Conversion Troubleshooting Checklist
What to try when a media file will not decode, convert, or play after conversion.
Check browser support
If a file fails to decode, the browser may not support the codec inside the file. The extension alone is not enough; two MP4 files can contain different audio or video codecs.
Try a smaller file
Very large files can stress memory, especially on phones. Test with a shorter clip to confirm that the format works before processing a long recording.
Use a common source format
MP4 with H.264 video and AAC audio is usually one of the safest inputs. WAV and MP3 are common audio inputs when supported by the browser.
Check the output
Always preview the converted file before saving or sharing it. Bylefian includes playback controls for the generated media so problems are easier to catch.
FAQ
Why does my MP4 not convert?
The browser may not support the codec inside that MP4.
Why is conversion slow?
Local conversion uses your device CPU and may take time for long or high-resolution files.
