HOW IT WORKS
1
Drop the aiff file
Drag your AIFF onto the page or click to browse. It is read locally, never sent anywhere.
2
Choose M4A and bitrate
Pick 128, 192, 256 or 320 kbps. 192 kbps is the default. Click Convert to start processing in this tab.
3
Save the m4a
The finished M4A downloads straight back to your device. Nothing touched a server on the way.
Why convert here, not there
No upload, ever
Your aiff file is decoded and re-encoded by code in this tab - a song, a memo, a podcast never leaves the device.
Local conversion
No upload time for a big aiff file, no server queue, no waiting on a download link.
No account, no daily cap
No daily caps, no "3 conversions left", no email wall. Convert the whole aiff library.
The two formats, briefly
| AIFF | AIFF is an audio container. This converter writes 16-bit PCM audio; a higher-bit-depth source can lose precision. | |
|---|---|---|
| M4A | M4A is an audio container. This converter writes AAC audio inside M4A, not Apple Lossless. | |
When you need this
- Use M4A when your receiving app or player does not accept AIFF. This page re-encodes the audio, so keep the original and check the download in that app before replacing it.
AIFF vs M4A: what changes
| AIFF | M4A | |

| Kind | Audio | Audio |
| Compression | 16-bit PCM output here | AAC audio output here |
| Typical size | Depends on the file and encoding settings. | Measure the exported file; it may be larger. |

Keep the original. Compare the exported file before sharing or replacing it.
Good to know
- The audio bitrate choices are 128, 192, 256 and 320 kbps, with 192 kbps as the default. Lower bitrates usually reduce size but can make loss more audible.
- First use downloads the audio/video engine (about 30 MB). The input cap is 2 GB, but available browser memory can run out below that.
AIFF to M4A, answered
Why convert AIFF to M4A?+
Use M4A when your receiving app or player does not accept AIFF. This page re-encodes the audio, so keep the original and check the download in that app before replacing it.
Which quality should I pick?+
The audio bitrate choices are 128, 192, 256 and 320 kbps, with 192 kbps as the default. Lower bitrates usually reduce size but can make loss more audible.
Does converting AIFF to M4A lose quality?+
This export uses lossy audio encoding. The source AIFF may contain different codecs or recording quality; re-encoding cannot improve the original. Compare the result before deleting the source.
Is there a file size limit?+
The hard cap is 2 GB per file. The practical limit is your device: conversion runs in its memory, so very large files can fail on phones with little free RAM. There is no server-side cap because nothing is uploaded.
Does my file get uploaded anywhere?+
No. EverywhereTrade has no server that receives files - the conversion code downloads once and runs entirely in this tab.
