Host an AAC file and share an audio link
Upload AAC audio and get an address that plays in the browser — better sound than MP3 at the same file size.

Any other file works too — up to 25.0 MB, or 100.0 MB for a whole site
Free to use. Your AAC file is live at your-name.99helpers.site in about ten seconds.
What is a .aac file?
AAC (Advanced Audio Coding) is the successor to MP3, standardised in 1997 and now the default for Apple Music, YouTube and digital broadcasting. At any given bitrate it sounds better than MP3, which is why it replaced it almost everywhere except in name recognition.
What people use AAC files for
- Audio for video and streaming
- Podcast and broadcast audio
- Music at smaller file sizes than MP3 allows
- Sound exported from video editing software
What opens a AAC file
- Every browser, phone and media player
- iTunes, Apple Music and Spotify
- Premiere, Final Cut and every video editor
How to host a AAC file
- 1
Drop your AAC 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: audio-track.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 scrubbing supported.
Why host a AAC file instead of emailing it?
AAC is what you get when you export audio from most video software, and it usually needs a link rather than an attachment — for a review, a voiceover handoff, or a clip someone needs to approve.
Worth knowing before you publish
- A raw .aac stream is less universally handled than the same audio in an .m4a container; if playback is inconsistent, remux to M4A.
- 128 kbps AAC sounds roughly like 192 kbps MP3, so you can use a lower bitrate for the same quality.
- For anything that will be edited further, send FLAC or WAV instead.
AAC hosting questions
- Is AAC better than MP3?
- At the same bitrate, yes — noticeably so at lower bitrates. It's the reason streaming services moved to it.
- Will it play in the browser?
- Yes. If a particular raw .aac file gives trouble, wrapping the same audio in an .m4a container is the reliable fix.
- Should I convert AAC to MP3?
- There's rarely a reason — AAC plays everywhere MP3 does and sounds better. Convert only if a specific old device requires it.
