How do I convert OGG to WAV?

Drop the .ogg, .opus or .oga file on the converter at the top of this page. 48 kHz is preselected; choose 16 kHz and Mono instead if a transcription service asks for it. Press Convert to WAV, check the preview and download the .wav file. Nothing to install and no account.

Can I convert a WhatsApp voice note to WAV?

Yes. Save the voice note as a file first: on iPhone, press and hold it, tap Share and Save to Files; on Android, share it to Files or Drive; on a computer, download it from the desktop or web app. It usually ends in .ogg or .opus. Drop it here and convert. Telegram voice notes work the same way.

Why is the WAV so much bigger than the OGG file?

The voice note is Opus, a codec that compresses speech hard; a WAV stores every sample uncompressed. A minute of 48 kHz stereo WAV is about 11.0 MB, and a 5-minute note about 54.9 MB. At 16 kHz mono the same 5 minutes is about 9.2 MB.

Which sample rate should I pick for OGG to WAV?

Match the destination. 48 kHz keeps Opus's own rate and suits video editors; 16 kHz mono suits speech-to-text services that ask for it; 44.1 kHz suits music projects; 8 kHz mono is for phone systems that require it. A rate higher than the recording adds size, not detail.

Is the voice note sent to a server?

No. Your browser decodes the voice note and writes the WAV on your own device, so a private message stays private, and closing the tab clears it. The page counts analytics events, such as a started conversion and the chosen sample rate; the file and its name are never sent.

OGG to WAV Converter

This free OGG to WAV converter turns a voice note or any OGG or Opus file into an uncompressed WAV that editors, transcription services and upload forms accept. It runs online in your browser, yet the voice note stays on your phone or computer: pick the sample rate, see the WAV's size, convert and download.

Drop your OGG or Opus voice note here or click to browse

OGG, OPUS or OGA (also MP3, M4A, FLAC, WEBM), up to 100 MB and 30 minutes.

The file is converted in your browser and is not uploaded.

How to convert OGG to WAV

Get the voice note out of the chat as a file, then three steps here.

1
Drop the .ogg or .opus file
Drag the voice note onto the converter or click to pick it from Files, Downloads or a folder. Files ending in .oga work too; so do MP3, M4A and FLAC if you have a mix.
2
Keep 48 kHz, or match the destination
48 kHz is preselected because Opus audio works at that rate. Pick 16 kHz and Mono for a transcription service that asks for it, or 44.1 kHz for a music editor. The expected WAV size shows once the length is read.
3
Convert, listen, download
Convert to WAV writes the file on your device. Play a few seconds in the preview to check it is the right note, then download it: same name, ending in .wav.

Only want the voice note to play on any device? A much smaller MP3 does that: use the OGG to MP3 Converter.

Getting a voice note out of WhatsApp or Telegram

The apps keep voice notes inside the chat. Menu names change between versions, so look for the nearest match.

iPhone
Press and hold the voice note, tap Share (or Forward and then the share button) and choose Save to Files. Then pick it from Files in the converter above.
Android
Press and hold the voice note and share it to Files, Drive or yourself by email; some phones also keep received audio in a folder a file manager can open.
Computer
In WhatsApp or Telegram for desktop or web, open the voice note's menu and choose Download or Save as. The file usually ends in .ogg or .opus.
A whole chat
Exporting the chat with media attached gives you every voice note in it as a separate file. Convert the ones you need, one at a time.

Why convert OGG to WAV

An OGG voice note is small and plays in the chat. A WAV is the file other software is sure to open.

Editing a voice note
Audacity, GarageBand and most DAWs open a WAV without asking for a codec, and cutting or levelling it adds no new compression each time you export a draft.
Sending it to a transcription service
Some speech-to-text services and research tools want WAV. Google's Speech-to-Text guidance asks for lossless audio, mono and a sample rate of at least 16 kHz.
A source's voice note, for a story
A source or a client answered by voice note. A WAV copy goes into the editing program, the archive or the producer's folder without a format question.
Upload forms and phone systems
Forms, portals and phone systems that list WAV reject .ogg and .opus. Convert to the rate they name, 8 kHz mono for many phone systems.

How big the WAV gets

A voice note is compressed hard; a WAV stores every sample. A minute of 48 kHz stereo WAV is about 11.0 MB; at 16 kHz mono, about 1.8 MB. The converter shows the estimate for your file before you convert.

16-bit WAV	1 minute	5 minutes	30 minutes
48 kHz stereo	11.0 MB	54.9 MB	329.6 MB
48 kHz mono	5.5 MB	27.5 MB	164.8 MB
44.1 kHz stereo	10.1 MB	50.5 MB	302.8 MB
16 kHz mono	1.8 MB	9.2 MB	54.9 MB
8 kHz mono	938 KB	4.6 MB	27.5 MB

Sample rate × 2 bytes × channels × seconds, plus a 44-byte header. One MB here is 1,048,576 bytes.

Which sample rate and channels to pick

Every WAV here is 16-bit PCM. Choose the rate and the channels the destination asks for.

48 kHz: the default
Opus decodes at 48 kHz (RFC 7845), so a 48 kHz WAV keeps the voice note's own rate. It is also the rate for a video edit.
16 kHz mono: speech-to-text
For a transcription service that asks for 16 kHz or mono. A 5-minute note is about 9.2 MB, against 54.9 MB at 48 kHz stereo.
44.1 kHz: music projects
Pick it when the WAV joins a 44.1 kHz music or podcast project, so the editor does not convert the rate.
Mono or stereo
A voice note is one person and one microphone. Mono halves the WAV and loses nothing you would hear; keep stereo only if the destination asks for it.

Converting OGG to WAV does not improve the sound

Opus is a lossy codec: when the note was recorded, the app kept what matters for a voice and threw the rest away. The converter decodes what is left and stores it as plain 16-bit samples (LPCM, the usual encoding inside a WAV, as the Library of Congress describes the format). The WAV sounds exactly like the voice note; it cannot add back what Opus removed.

What you gain is compatibility and a file that loses nothing more when you edit it. What you pay is size: the WAV is many times larger than the .ogg it came from.

A higher sample rate does not help either. Google's guidance for its Speech-to-Text service says there is no benefit to up-sampling: frequencies the recording did not capture stay missing.

Browsers that convert OGG and Opus

The converter uses your browser's own decoder. Chrome, Edge and Firefox decode Opus and Vorbis in an OGG file. Safari added the OGG container for Opus and Vorbis in Safari 18.4 (macOS Sequoia 15.4, iOS and iPadOS 18.4).

On an older iPhone or iPad every browser uses Apple's engine, so switching browsers does not help: update iOS, or convert on a computer or an Android phone. If a file fails, the converter says so and suggests what to try.

The OGG to MP3 page has a table of browser support for OGG and Opus.
