Audio to Base64

Convert audio to Base64 online and use the result string as data URI, HTML object, JavaScript Audio, and others. Sometimes you have to send or output a sound file within a text document (for example, HTML, JSON, XML), but you cannot do this because binary characters will damage the syntax of the text document. To prevent this, for example, you can encode sound file to Base64 and embed it using the data URI. Please note that the audio to Base64 encoder accepts any sound files types with a size of up to 50 MB. If you are looking for the reverse process, check Base64 to Audio.


How to convert a sound file to Base64

  1. Choose the source of sound file from the “Datatype” field.
  2. Paste the URL or select a local sound file from your computer.
  3. If necessary, select the desired output format.
  4. Press the “Encode audio to Base64” button.
  5. Download or copy the result from the “Base64” field.

Additional audio encoders

The Audio to Base64 converter generates ready-made examples, depending on the selected output format. It automatically detects the content type of the uploaded sound file, so that you simply copy the complete result. If you need to encode specific audio formats, please follow the links below:

Output formats

If you do not know what output format you need, check the following examples to see how will look the result of the same Base64-encoded sound file formatted in each of the available formats:

If I missed an important output format for Base64-encoded audio files, please let me know — I would love to implement it.

  • Lefteris,
    Very good page.

    Maybe try to make some visual changes.
    • Administrator,
      Hi! Thank you for your comment. Could you please share some ideas or describe the problems encountered?
      • GoldenFirster,
        i think he means the css? and if so, i agree. this is a very useful webpage but it could use some proper styling
  • kang,
    Hello, this is very useful Web page!

    in the results of the transformation, how many times sampling rate?

    I need a 48k Hz audio sampling integer data.

    in the C program, it is possible to just copy the ascii code to the list for output-sound?
  • Steve,
    Very useful site. Thank you! I used this site to encode a .flac file to a Data URI and then had javascript play it using new Audio.
  • HECTOR,
    How could I convert Base64 text to audio?
  • waqar,
    it is best website to convert things
  • Hung,
    good job bro (gút chóp em)
  • plainqin,
    It's COLLLLLLLLL. For MacOS audio file format `.m4a`, python's base64 library have a bad operate experience. This website is COLLLLLLLLLLLLLL
  • Yafjeff,
    Great soft screen got multicolored
  • Dev,
    Hi,

    I like the functionality.

    I am looking to write similar functionality for my current project to convert wav file present at URL to Base64

    Are you comfortable in sharing your code or give some idea about it. Your help is really appreciated.

    Thanks,
    Dev
