QR Codes

You can turn your .mp3 file into a QR code for free using two simple methods.

One uses a file upload QR generator like Linko, and the other shares a public link to your audio hosted online.

Both work well depending on where your file is stored and how you want to share it.

Here’s a breakdown of both methods, step-by-step:

If you don’t want to host your audio elsewhere, Linko offers a direct file upload feature.

You can create a free account and upload your .mp3 file directly into a QR code that plays the audio when scanned.

Steps to convert MP3 to QR code using Linko:

  1. Sign up for a free account at Linko.

  2. Go to the Create QR section in your dashboard.

  5. Customize your QR code with colors, logo, or shapes (optional).

  6. Click Generate and download your scannable QR code.

Best part?

Linko hosts the audio for you, so there’s no need to upload your MP3 anywhere else.

You can also edit the file later without changing the QR code. It’s ideal for podcasters, musicians, teachers, or anyone sharing audio content in public spaces.

This method works if your .mp3 file is already uploaded to Dropbox, Google Drive, or any public hosting service.

You simply paste the shared file link into any free QR generator.

Steps using an external hosting service:

  1. Upload your MP3 to a cloud service (Google Drive, Dropbox, etc.).

  2. Set the sharing permissions to “Anyone with the link can view.”

  3. Copy the direct share link of the audio file.

  4. Paste this URL into any QR code generator (like Linko’s free QR code tool).

  5. Customize and download your QR code.

This method gives you more storage flexibility but doesn’t allow editing the destination later, unless you use a dynamic QR platform.

Use Cases for MP3 QR Codes

  • Musicians sharing tracks at events or merch tables
  • Teachers embedding audio instructions on worksheets
  • Podcasters linking episodes from business cards
  • Businesses playing audio guides or ads via print media

Both methods help you convert your .mp3 file to a scannable QR code for free.

If you want to skip hosting and get a ready-to-play audio QR, Linko’s direct upload feature is the simplest and fastest option.
