OpenAnyFile
Works
Viewing, inspecting and verifying. You get a playback bar with duration and seeking. File details, exact byte size and the detected signature are always shown.
How to open a .aiff file
AIFF files come from Pro audio on macOS, and the usual advice — buy the software that made it — is rarely what you need just to look inside one. This page covers what the format is and how to open it in a browser tab.
What is a .aiff file?
Audio Interchange File Format is an audio format developed by Apple, first appearing in 1988. It is normally produced by Pro audio on macOS.
Same as .aif. Holds full ID3-style metadata more reliably than WAV does, which is why mastering houses prefer it.

Open a .aiff file in your browser
OpenAnyFile routes .aiff to its HTML5 audio player, which plays a playback bar with duration and seeking.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .aiff file onto the drop zone, click to browse for it, or paste it with Ctrl+V.
- The extension is detected and the file is handed to the HTML5 audio player.
- Your AIFF opens on its own viewer page: a playback bar with duration and seeking.
- Use fullscreen for a closer look, or download the file back out unchanged. Nothing is transmitted anywhere — the parsing happens in your own browser process.
What you can and cannot do with it here
Does not work
Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need special software or an equivalent.
No upload, and here is why that matters for {E}
Handing a .aiff file to a random conversion site means handing over a copy you cannot get back. OpenAnyFile parses the file locally instead — the same way special software reads it off your disk, except the reader happens to be a web page. Nothing is transmitted, so there is nothing to leak, log or subpoena. It also means it keeps working with your Wi-Fi switched off.
Frequently asked questions about AIFF files
Can I open a .aiff file without installing special software?
Yes. OpenAnyFile's HTML5 audio player runs in your browser, so you can read a AIFF file with nothing installed. You get a playback bar with duration and seeking. For full editing you still need the original application — this is a viewer, not an editor.
How can I check a file really is a AIFF file?
Look at the first bytes rather than the extension. A genuine AIFF begins with 46 4F 52 4D .. 41 49 46 46. Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .aiff by mistake is easy to spot.
Is it safe to open a AIFF file online?
With OpenAnyFile, yes, because nothing is uploaded. The file is read locally through your browser's File API and never leaves your device, so there is no server copy to leak, log or retain. That matters most for the kind of file people are least willing to hand to a random converter site.

Does the same viewer handle formats related to AIFF?
Yes — the same engine also opens .mp3, .flac, .wav, so you can compare related files without switching tools.
