Use Echora to convert .aiff or .aif audio to WAV for editing or delivery. Upload one file and download the WAV when conversion finishes. The tool is free and requires no account or software installation.
The output is fixed at 16-bit PCM WAV. A 24-bit or higher-bit-depth AIFF cannot retain its full original precision in this output. Keep the source for further editing or precise archiving.
What changes between AIFF and WAV?
AIFF and WAV are containers commonly used for PCM audio. WAV can contain several encodings, as described in MDN's container guide; this tool specifically writes uncompressed, signed 16-bit little-endian PCM.
| Property | AIFF input | This tool's WAV output |
|---|---|---|
| Extension | .aiff or .aif | .wav |
| Container | AIFF | WAV |
| Audio | Commonly PCM; the file must be decodable | 16-bit PCM |
| Byte order for typical PCM | Big-endian | Little-endian |
| Precision | Depends on the source, including 16-bit or 24-bit | Fixed at 16-bit |
| Main use here | Original recording or export | Copy for a workflow requesting WAV |
Changing the container or byte order is different from reducing bit depth. The former does not inherently reduce PCM precision; the latter can. Check the source's properties and the requested WAV specification before converting material that needs exact preservation.
When converting AIFF to WAV is useful
Deliver a file with a WAV requirement
A client or upload form may ask for WAV even though your existing export is AIFF. Make a copy and test it in the destination application. Confirm that 16-bit PCM is acceptable, along with the sample rate and channel layout. A request for 24-bit or floating-point WAV needs a different output configuration than this page provides.
Import an existing recording into an editor
An editor or project may work more conveniently with WAV assets. Converting an individual AIFF can supply that input without changing your original file. Check the start, end, and channel balance after importing. If the editor already reads your AIFF correctly, conversion may not be necessary.
Keep a high-precision original alongside the copy
For a 24-bit recording, retain the AIFF for future edits or archive use and create a 16-bit WAV only when that copy meets the recipient's needs. This lets you deliver the requested file without replacing the more precise source. Repeated conversion cannot bring back precision discarded in an earlier step.
How to convert AIFF or AIF to WAV online
- Upload one file. Select or drag in an
.aiffor.aiffile up to 200MB and 30 minutes. The upload area shows file information; browser playback of the input is not required. - Start the conversion. Wait for the upload to finish and start the task. WAV is already selected. The service checks the audio and duration, then creates the 16-bit PCM output.
- Check and download. When the task completes, preview the WAV if supported and save it. Open the downloaded copy in its intended editor or player before handing it over.
Use an actual audio file that has finished exporting or downloading. A damaged file or unsupported internal encoding can still fail on the service even if its extension is accepted. Try opening the original in its source application if processing reports a read error.
What to inspect in the downloaded WAV
Check that the file is identified as PCM, 16-bit, with the expected duration, sample rate, and channels. A generic “WAV” label does not tell you the bit depth. Listen to both channels of stereo material and compare quiet endings so you know the intended recording is present.
This page has no bit-depth, sample-rate, channel, dither, or target-size controls. The output uses fixed PCM encoding, not a selectable compressed-audio bitrate. If a production specification asks for particular settings, compare them with the actual file rather than assuming that any WAV will qualify.
Review tags, markers, and loop-related information separately. A usable audio track does not guarantee complete transfer of AIFF's non-audio data into the WAV.
Is AIFF to WAV conversion lossless?
For 16-bit PCM AIFF, a conversion that preserves sample rate and channels can preserve the decoded audio samples. The two files will still have different headers and byte layouts, so different file checksums alone do not establish an audible change. Exact audio comparison requires comparing decoded samples in the same representation.
For 24-bit or other higher-precision input, this tool's 16-bit output has less available precision. Do not treat it as an exact replacement for the source. That distinction matters even when a short listening test sounds the same or both files report the same sample rate.
Compare at similar volume through the same equipment, especially for quiet passages and fades. Format conversion does not repair distortion, noise, or missing detail in the original recording. Keep the source when further processing or precise archiving is planned.
Will the WAV file be smaller?
A 16-bit PCM AIFF and a 16-bit PCM WAV with the same sample rate, channel count, and duration contain the same amount of audio data. Their total file sizes may differ because of headers and metadata. Changing the container alone generally does not make equivalent PCM audio substantially smaller.
Use bytes ≈ sample rate × channels × bytes per sample × seconds for an estimate. At 48kHz, stereo, and two minutes, 16-bit PCM contains about 23.04MB, while 24-bit PCM contains about 34.56MB. These decimal-MB calculations omit headers. The smaller 16-bit version reflects reduced precision, not lossless compression or a measured result from your file.
The source must fit the upload limit first. A large AIFF cannot bypass 200MB simply because its 16-bit WAV might be smaller. Prepare a suitable excerpt separately if the recording exceeds the size or duration limit.
Frequently Asked Questions
Is the AIFF to WAV converter free?
Yes. No account or credits are required. Each task accepts one .aiff or .aif file up to 200MB and 30 minutes; this page does not support batch uploads.
Are .aif files supported too?
Yes. This page accepts both .aiff and .aif. It does not accept the separate .aifc extension; changing a filename does not confirm that the underlying audio is compatible.
Will I get a 24-bit WAV from a 24-bit AIFF?
No. Output is fixed at 16-bit PCM WAV. A 24-bit source cannot retain its full original precision in that output, so keep it for work requiring higher bit depth.
Can the conversion preserve a 16-bit AIFF exactly?
For 16-bit PCM input, decoded audio samples can be preserved when sample rate and channels remain unchanged. This does not promise identical file bytes or complete metadata transfer, and it does not apply as a blanket guarantee to higher-bit-depth or unusual AIFF files.
Can I choose the sample rate or bit depth?
No. The page provides no sample-rate, bit-depth, channel, or dither selector. Check the saved WAV's properties against your delivery specification.
What if my browser cannot preview the AIFF?
Input playback is not required because AIFF uses a file-information preview. The service must still decode the audio and validate the 30-minute limit. After a successful task, download the WAV and test it in the receiving application.
Can I rename .aiff to .wav instead?
No. Renaming does not rewrite the container or PCM byte layout. Use conversion to create a WAV file that the destination can recognize correctly.
