  • Clear browser cache and reload the page
  • Try a different browser
  • Disable browser extensions or ad blockers

Conversion Failures

Issue: File fails to convert

Solutions:

  • Check that your browser supports WebAssembly (FFmpeg)

Quality Issues

Issue: Converted file quality is poor

Solutions:

  • For audio: use higher bitrate or lossless formats (FLAC, WAV)
  • For video: choose H.264 codec and higher bitrate for better quality
  • For images: use WEBP or PNG formats for lossless conversion
  • Ensure source file is high quality before conversion
  • Test with sample to verify output quality

Device Compatibility

Issue: Converted file won't play on device

Solutions:
