AMR to WAVPCM Converter
Processing entirely on your device — large files may take a moment.
Adaptive Multi-Rate Audio and Raw PCM Wave (WAVPCM) exist for different jobs: AMR is the tiny voice-recording format of old Nokia-era phones and answering machines. Convert WAVPCM files exactly like WAV — to MP3, FLAC or any target.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.
How AMR compares to WAVPCM
| AMR | WAVPCM | |
|---|---|---|
| Compression | Lossy speech codec | Uncompressed PCM |
| Quality | Speech only | Bit-exact |
| Compatibility | Phone recorders | Universal |
| Best for | Voice memos and call recordings | Recording and editing masters |

About the AMR format
AMR (Adaptive Multi-Rate) is the speech codec of 2G/3G telephony, and the default recording format of countless feature phones and early smartphones. It is optimized exclusively for human voice: narrowband (300–3400 Hz) and wideband (AMR-WB, 50–7000 Hz) modes that make calls sound like calls.
For voice memos it is remarkably compact — a few kilobits per second. For anything musical it is hopeless: cymbals, bass and anything above its band simply do not exist. Convert AMR voice notes to MP3/Opus for archiving and playback anywhere else.
+Strengths
- ✓Extremely compact for speech
- ✓Native phone-recorder format
!Limitations
- −Voice-only: music quality is unusable
- −Narrow bandwidth sounds dated
About the WAVPCM format
WAV is the simplest possible audio file: PCM samples — the raw digits of the waveform — inside a RIFF container. CD-quality stereo (44.1 kHz, 16-bit) runs about 10 MB per minute, and studio work uses 24-bit/48–96 kHz without blinking. Every DAW, every interface and every phone records to it; nothing about it can be misinterpreted.
That perfection is why WAV remains the format of recording and editing: every sample is bit-exact, so processing, slicing and mixing never fight artifacts. And it is why nobody streams it — ten megabytes a minute is storage money, not delivery.
+Strengths
- ✓Bit-perfect, zero-loss audio
- ✓The editing and recording standard
- ✓Supports hi-res depths and sample rates
!Limitations
- −Enormous files (~10 MB/minute at CD quality)
- −Tagging is an afterthought (BWF fills the gap)
- −Impractical for streaming or phones-on-the-go libraries
Why convert AMR to WAVPCM?
Think of it as moving your file to the container that fits the job. Voice-only: music quality is unusable WAVPCM works differently: Bit-perfect, zero-loss audio If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this AMR to WAVPCM converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for AMR to WAVPCM?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Can I convert a whole folder of AMR files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
Will converting AMR to WAVPCM reduce audio quality?
If WAVPCM is lossless, the output contains everything the AMR file contains — no further loss is added. If WAVPCM is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
