Extracting Audio: MP3 vs WAV vs Opus
Which format to choose when you only want the sound, and why the source quality caps everything.
Why Extract Audio at All?
Plenty of reasons are perfectly legitimate: archiving a voiceover you recorded, keeping a reference copy of a sound you have licensed, saving your own podcast clip, or pulling narration out of a tutorial so you can listen while commuting.
vGram handles this with the Audio Only option — tick it before downloading and choose one of four formats.
The One Rule That Governs Everything
You cannot add quality that was never there. Instagram and TikTok compress audio heavily on upload — typically AAC at somewhere between 64 and 128 kbps. Converting that to a lossless WAV does not recover detail. It produces a much larger file containing exactly the same compressed audio.
This is the single most misunderstood point about audio extraction. Every format below is working from the same already-compressed source.
The Four Formats
MP3 — the default choice
Nearly thirty years old and still the most compatible audio format in existence. Every phone, car stereo, DAW, and browser handles it. It is lossy, and re-encoding from the platform's AAC adds a second generation of loss, but at these bitrates the difference is very hard to hear.
Choose MP3 when you want the file to simply work everywhere. This is the right answer for most people.
WAV — uncompressed, and usually unnecessary
WAV stores raw PCM audio with no compression. Files are roughly ten times larger than the MP3 equivalent. Because the source was already lossy, WAV preserves the compressed audio faithfully rather than improving it.
Choose WAV when you are importing into an editor that prefers uncompressed input and you want to avoid further generation loss during your own editing. Otherwise it is wasted disk space.
OGG Vorbis — efficient and open
An open, royalty-free format that generally beats MP3 at the same bitrate. Support is good on Android, Firefox, and Chrome, but patchier across older hardware and Apple's ecosystem.
Choose OGG when you want better efficiency than MP3 and you control where the file will be played.
Opus — technically the best, least universal
The most modern codec of the four and clearly the strongest at low bitrates — it is what most voice and video calls use. Excellent for speech in particular.
Choose Opus when you are saving spoken content, care about file size, and know your playback target supports it.
Quick Comparison
| Format | Compression | Relative size | Compatibility | Best for |
|---|---|---|---|---|
| MP3 | Lossy | Small | Universal | General use, sharing, car and phone playback |
| WAV | None | Very large | Universal | Importing into an audio or video editor |
| OGG | Lossy | Small | Good | Android and web playback |
| Opus | Lossy | Smallest | Modern only | Speech, podcasts, low-bandwidth storage |
How to Extract Audio With vGram
- Copy the link to the Instagram reel or TikTok video.
- Paste it into vGram.
- Tick Audio Only. The video quality selector greys out, since it no longer applies.
- Pick your format from the dropdown.
- Download.
Practical Recommendations
- Just listening? MP3.
- Editing in Premiere, Resolve, or Audition? WAV, to avoid stacking another lossy generation.
- Archiving lots of speech? Opus, for the size savings.
- Unsure? MP3. It is the safe default and always will be.
The Licensing Reality
Most trending sounds on TikTok and Instagram are commercial music, licensed to the platform for use inside that platform. That licence does not extend to you.
Extracting a track for private listening is one thing. Using it in a monetised video, a client project, or a commercial release is a different matter entirely and typically requires a proper licence from the rights holder.
Audio you recorded yourself is yours to extract freely. For everything else, check before you publish — our Terms and Conditions set out what is and is not acceptable.
