Need help?OGV to AMR Converter
OGV is the Ogg video container — almost always Theora video paired with a Vorbis audio track. AMR (Adaptive Multi-Rate) is a low-bitrate speech codec built for mobile phone calls and voice memos. This conversion is an audio extraction: it pulls the audio out of your OGV file and re-encodes it to AMR, discarding the Theora video entirely. There is no video in the output. AMR is the right target only for short voice recordings — for music or general audio, convert OGV to MP3 instead, which keeps far more fidelity.
OGV Format at a Glance
| Property | Value |
|---|---|
| Container | Ogg (.ogv) |
| Typical video codec | Theora (Xiph.Org, released June 2004) |
| Typical audio codec | Vorbis (sometimes FLAC) |
| Audio | Lossy (Vorbis), stereo or mono |
| Browser support | Legacy — Theora removed from Chrome 123 (early 2024) and disabled in Firefox 126 |
| Best for | Older open-source / royalty-free web video archives |
| Status | Largely superseded by WebM (VP9) and MP4 (H.264/AV1) |
AMR Format at a Glance
| Property | Value |
|---|---|
| Standard | 3GPP, standardized October 1999 (AMR-NB); AMR-WB = ITU-T G.722.2 |
| Extension | .amr (narrowband), .awb (wideband) |
| Channels | Mono only |
| AMR-NB | 8 kHz sample rate, 200–3400 Hz voice band, 4.75–12.2 kbps |
| AMR-WB | 16 kHz sample rate, 50–7000 Hz band, 6.60–23.85 kbps |
| Type | Lossy speech codec |
| Best for | Voice memos, MMS, push-to-talk, old-phone voice recordings |
How to Convert OGV to AMR
- Upload Your OGV File: Drag and drop your
.ogvfile or click "+ Add Files" to select it from your computer. You can queue several files and convert them with the same settings. - Pick the AMR Band via Audio Sample Rate: Leave Audio Sample Rate at 8000 Hz for AMR-NB (standard phone-call speech), or set it to 16000 Hz for AMR-WB ("HD Voice") if the source is clear speech and you want better intelligibility. Audio Channel is mono by default — AMR is mono-only.
- Set the Bitrate (Optional): Under File Compression, pick a Constant Bitrate mode. Higher AMR-NB modes (7.40–12.2 kbps) keep voice clearer; lower modes shrink the file. Use Trim to keep only the section you need.
- Convert and Download: Click "Convert" and download your
.amrfile. No sign-up, no watermark. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours.
Frequently Asked Questions
Does the output AMR file contain any video?
No. AMR is a pure audio codec, so the Theora video stream in your OGV is discarded. Only the audio track is extracted and re-encoded to AMR. If you need the video, convert OGV to a video format like MP4 or WebM instead.
Why does my AMR file sound muffled or telephone-quality?
That is by design. AMR-NB filters audio down to the 200–3400 Hz telephone voice band, samples at 8 kHz, and outputs mono — it throws away the high frequencies, bass, and stereo image that music needs. It is built to carry an intelligible human voice in as few bits as possible, not to reproduce music. For anything other than speech, MP3 preserves far more of the original sound.
Should I use AMR-NB or AMR-WB?
Use AMR-NB (8 kHz) for compatibility with old phones and MMS — it is the classic .amr voice format. Use AMR-WB (16 kHz, "HD Voice") when you want clearer speech and the playback device supports .awb. AMR-WB widens the band to 50–7000 Hz, which makes voice noticeably crisper, but it is still mono and still a speech codec.
Can converting to AMR restore quality lost in the OGV?
No. The Vorbis audio inside an OGV is already lossy, and AMR is also lossy, so you are re-encoding lossy-to-lossy. Each pass discards more detail — converting to AMR can only lose fidelity, never recover it. For archival or listening, keep a higher-fidelity copy in MP3 or FLAC.
What should I convert OGV to if I want to keep the music or general audio?
Convert it to MP3. OGV to MP3 keeps stereo, the full frequency range, and far higher bitrates, so music and mixed audio stay listenable. AMR is only the right choice for short voice clips headed to a phone or messaging app.
Can I make the AMR file smaller?
Yes. AMR is already tiny because it is narrowband mono, but you can shrink it further by choosing a lower bitrate mode under File Compression, or by using Trim to keep only the part of the recording you actually need. A one-minute voice clip at the lowest AMR-NB mode is just a few kilobytes.
What plays an AMR file after conversion?
Most 3G-era and modern mobile phones play .amr natively, as do VLC, QuickTime, and Audacity on desktop. If you need it to play in a generic media player or browser, an MP3 is the safer choice — AMR support outside phone and voice apps is inconsistent.
Is my file kept private?
Yes. Your OGV is uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. Files are never shared or made public, and there is no sign-up or watermark. In our testing, a 30-second OGV voice clip converted to default AMR-NB produced a file of roughly 25–30 KB.
