What does the AIFF to WMA audio converter do?
+
AIFF is lossless audio; WMA is lossy. The converter re-encodes the waveform at a configurable bitrate. The result is much smaller but discards some inaudible frequency content — usually transparent at 192 kbps+.
What bitrate should I pick for WMA?
+
320 kbps for archival quality, 256 kbps for transparent listening on most speakers, 192 kbps for streaming, 128 kbps when file size dominates. Below 96 kbps artifacts become audible on percussive content.
Is the AIFF to WMA conversion reversible?
+
You can convert the WMA back to AIFF on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
How much smaller will the WMA be than my AIFF?
+
Typically 5-10x smaller for images, 5-15x smaller for audio. Exact ratio depends on the chosen quality level and the content — flat solid-colour images and silent audio compress far more than detailed photos or busy soundtracks.
Is there a file-size limit when converting AIFF to WMA?
+
Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.
Can I batch-convert several AIFF files to WMA at once?
+
Yes. Drop or pick multiple AIFF files in one upload — the converter processes them in parallel and returns a ZIP of the WMA results. There is no need to repeat the upload step per file.
What happens to my AIFF files after the conversion?
+
Uploaded files and WMA outputs are auto-deleted after a short retention window. We do not inspect, share, or train on user files. Direct download links are time-limited and tied to your session.
What apps can play a WMA file?
+
WMA plays in most music players, browsers, and media libraries. iTunes / Apple Music, VLC, Foobar2000, and phone media apps handle it natively.
Do I need to install software to convert AIFF to WMA?
+
No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
Do I need an account to convert AIFF to WMA?
+
No. AIFF to WMA conversion is free and works without an account. Signing in unlocks higher file-size caps, batch history, and API access.
Is there an API for AIFF to WMA conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. AIFF to WMA is one of the supported pairs.
What if my AIFF fails to convert to WMA?
+
Failures are usually caused by corrupted source files or unsupported AIFF variants. Re-export from the original app and try again; if it still fails, the contact page forwards the file to support so we can diagnose.
