Download Instagram audio: use the MP3 button

To save just the audio from a public Instagram Reel, paste the link into Vidlune and choose Download MP3. The tool returns a single .mp3 file — the video is not included. In a measured test, that MP3 was 287,967 bytes and its audio stream was 8.83 seconds at 260.8 kbps.

What the button does

The MP3 button returns audio only

The Instagram downloader has two buttons: Download MP4 and Download MP3. Download MP4 returns the video with its audio track in one file. Download MP3 returns the audio track on its own as an .mp3 file, with no video. They use the same public-link box and the same download allowance.

If your goal is a clip you can drop into an editor or play while doing something else, the MP3 is the smaller file: in the test below it was about 281 KiB, against about 3.41 MiB for the same Reel as MP4.

The download path

How to download Instagram audio

  1. Copy the link to a public Instagram Reel, feed video or IGTV post.
  2. Paste the Instagram URL into the public-link box on the downloader.
  3. Choose Download MP3 and wait for the request to finish.
  4. Save the .mp3 your browser downloads from the response.

The downloader accepts public Instagram Reel, feed-video and IGTV URLs. It does not ask for an Instagram login, and it cannot fetch private, deleted, login-gated or non-video links.

Measured, not estimated

What one real download returned

The numbers below come from a test download run through the live tool on a public Instagram Reel. They are the actual response values, not rounded marketing claims.

The MP3 bitrate follows what the extractor pulled from the source; this walkthrough does not claim a specific quality label for it. The MP4 figures are included as a regression check — the video path was unchanged by the addition of the MP3 button.

How the audio is extracted

What runs when you pick MP3

For an MP3 request, the server runs yt-dlp with --extract-audio --audio-format mp3 --audio-quality 0 and selects the best available audio stream (format ba/b). It returns that audio track as the .mp3 file. The MP4 request uses a different yt-dlp format string and remuxes to MP4; the two buttons share the same quota and the same public-link checks.

Limits that apply

Quota and supported links

Each visitor can complete three successful downloads in a rolling 24-hour window, and that count is shared between the MP3 and MP4 buttons — an MP3 and an MP4 from the same link use two of the three. Failed or rejected links do not use the allowance. Only public Instagram links are supported; the tool never asks for an Instagram password, session cookie or access token.
