Will an M4A file play in the browser?

Yes, in the browser's built-in player. AAC in an MP4 container is supported everywhere, so there's nothing for the listener to install.

Should I convert M4A to MP3?

Usually not. M4A is supported just as widely and sounds better at the same bitrate; converting only loses quality.

How do I share an iPhone voice memo?

Export the memo, transfer it to a computer, and drop the .m4a here. The resulting link plays on tap for anyone you send it to.

Host an M4A file and share an audio link

Upload M4A audio and get an address that plays straight in the browser — the format iPhones and Macs record in.

You can host:

Drop your M4A file here

Any other file works too — up to 25.0 MB, or 100.0 MB for a whole site

Free to use. Your M4A file is live at your-name.99helpers.site in about ten seconds.

What is a .m4a file?

M4A is AAC audio in an MP4 container — the format Apple's Voice Memos, GarageBand and iTunes produce. At the same bitrate it sounds noticeably better than MP3, and every browser and phone plays it.

What people use M4A files for

Voice memos and interview recordings from an iPhone
Podcast audio and voiceover
Music exported from GarageBand or Logic
Audio notes sent instead of a long written explanation

What opens a M4A file

Every browser, phone and media player
iTunes, Apple Music, Voice Memos and GarageBand
Audacity, Logic and most audio editors

How to host a M4A file

1
Drop your M4A file in
Drag it onto the box at the top of this page, or click to choose it. Files up to 25 MB are supported, and nothing is uploaded until you publish.
2
Pick an address
Type a name and we'll tell you straight away whether it's free. That becomes the link: voice-note.99helpers.site
3
Publish and share
Create a free account — that step exists so the file is yours to update, replace or delete — and the link is live within seconds.

The same three steps work for any file — see how file hosting works on 99helpers.com.

What happens when someone opens the link

The audio plays in the browser's built-in player with a scrubber, so listeners can skip around without downloading anything.

Why host a M4A file instead of emailing it?

A voice memo explaining something is often faster than writing it, but it's awkward to send — too big for some mailboxes, recompressed by messaging apps. A link plays on tap, on any device.

Worth knowing before you publish

M4A sounds better than MP3 at the same bitrate, so there's rarely a reason to convert.
For speech, 64–96 kbps mono is plenty and keeps files small.
25 MB holds roughly 45 minutes of speech at 64 kbps.
