How to convert MID to M4A?

You can convert MID to M4A with MConverter in three easy steps:
  1. Choose MID files from your device or cloud storage
    At the top of this page, drag and drop your MIDs.

    Alternatively, click on the Browse box to select files with your device's file picker, or copy and paste a MID file by pressing Ctrl+V (or ⌘+V on Mac).

    MConverter can easily import MIDs from Google Drive, OneDrive, and Dropbox.

    Converting a folder with MID files to M4A is also supported: simply paste, drag and drop it, or use the ADD FOLDER button.
  2. Click or tap on M4A from the list of target formats
    You could also use the search box at the top right to quickly find the format you need, whether it's M4A or something else.
  3. Get your M4A files after MConverter has finished processing them
    Click on DOWNLOAD ALL to save your M4As to your default downloads folder, or select SAVE TO to choose another location.

    You can also configure automatic file downloads during the conversion process or in the settings menu. When enabled, each M4A file is downloaded as soon as its conversion is complete, without waiting for the others to finish.

    If supported by your device, you'll see a Share icon, allowing you to directly send converted files to other apps.

Format description

A MID (or MIDI) file describes music data in the Musical Instrument Digital Interface technical standard. Unlike other audio formats like MP3, it specifies the individual music notes, their duration and loudness, as well as the instruments used. Because of that, a MIDI file may sound differently on different systems.
In order to make it consistent, you can convert it to another audio format.
File extension .m4a
Category Audio file formats
Developed by Apple
Mime type audio/m4a

Format description

M4A files store audio using the AAC codec. M4A stands for MPEG-4 Audio. It is very similar to MP4 with the difference being the lack of a video/subtitle track in the file.

I love that I can just convert my files from File Explorer, no need opening the app first, just right click and "open with" or the "Share" button and choose "MConverter" immediately or drag the file to MConverter home screen if I'm in a rush. Even though it's a web wrapper, it still serves a distinct purpose, compared to other website converters.

What I appreciate most is how user-friendly it is. It handles just about any file conversion I throw at it, quickly and efficiently. It's become an indispensable tool in my daily workflow. The fact that it supports so many formats is a huge plus, and it's saved me a lot of time and hassle. It's a solid, reliable tool, and I'd definitely recommend it to anyone who needs to convert files regularly.

I love this converter! It's free and easy to use, and it successfully converted .mov with transparent background to .png with transparent background in only a few seconds. It will now live permanently in my Tools bookmark folder :)

Excellent tool, it does exactly what it says it will do. It does it really quick. No fuss, just upload your file in the web interface, select the output and the download of your formatted file begins almost immediately. Super fast !

AMAZING APP! I am so glad I found it!! It actually converts WEBM files without the weird bleeds! It's the only app I use to convert cute emotes from any site! I have been looking for years to find an image/gif converter but all the ones I found didn't convert emotes correctly. MCONVERTER DOES!! Hands down, best app!

I tried several programs to convert AI files to PNG, but only this program managed to convert both the text and the image exactly as in the original. The other programs transformed the text using their own fonts, which were not the ones originally used.

An exceptional product, with a fantastic, simple, immediate effective UX. A spatial combination of which format can be converted to which other format. A fast and flawless execution, with a very high quality of the output that maintains practically all the characteristics of the original document.

What truly sets MConverter apart is its Swiss Army knife-type functionality. This tool can convert anything to anything with just a click of a button. It doesn't matter whether you're working with audio, video, documents, images, or any other file type - MConverter has got you covered.

This app is exactly what I asked for and is super easy to use. I am not a big time computer wizard so I need apps that do what they say do in a straightforward process. This app does just that! I love it and will continue to use it and will advise others of it as well. Good job to the owners/developers! And, sincere THANK YOU!

The most fantastic, fastest, best and easiest file converter I have ever had installed on my mobile. You deserve all the praise possible, more than happy, I am super grateful, I will always be grateful to you for this super fantastic application. This super fantastic app has literally saved my life, now I can read novels and books in any format, including pdf, which has very small print, in epub format👏

AMAZING! This is the perfect file converter! The first thing I used it for was to convert WMV files to MP4 and it worked flawlessly. I then realized it supports all kinds of formats and is basically unlimited. The UI is very user-friendly and super easy to navigate. Incredible app, MConverter!
