Learn More about AudioWeaverWhy use this audio converter?
Many modern messaging apps use highly compressed audio formats like Opus and AMR to save bandwidth. While efficient, these files often trigger "file not supported" errors when you try to open them in regular media players or import them into video editors.
Our free online audio converter instantly transforms these stubborn files into universal formats like MP3, AAC, and WAV. Because it uses client-side WebAssembly technology, your private voice messages and audio files are never uploaded to our servers—ensuring 100% privacy and lightning-fast conversions.
Audio Converter FAQ
How do I convert WeChat or Telegram voice messages to MP3?
Simply upload your .opus, .amr, or .ogg file to this online audio converter. Select MP3 as the output format and click Convert. It runs directly in your browser without uploading your private voice messages to a server.
Why can't I open .opus or .amr files?
Formats like Opus and AMR are optimized for low-bandwidth voice messaging in apps like WeChat and Telegram. However, they aren't widely supported by default media players on Windows or Mac. Converting them to a standard format like MP3 or WAV solves this.
Is there a file size limit for the audio converter?
Since the conversion uses FFmpeg.wasm to process the audio locally on your device, the file size is only limited by your browser's memory. Most voice messages will convert in seconds.
Which formats are supported?
You can input .opus, .amr, .ogg, .wav, and .m4a files. Supported export formats include MP3 (universal), AAC (great for Apple devices), and WAV (lossless quality).
