Cut WMA, AIFF and APE online
Browsers cannot decode WMA or AIFF, so this page converts your file on our server first, then trims it in your browser. Your file is uploaded for that conversion — if you need a tool that never uploads anything, use the Audio Trimmer for MP3, WAV, FLAC, M4A, AAC, OGG and Opus.
WMA, AIFF and APE are the three common audio formats a web browser will not open. Every browser-only audio editor — including our own Audio Trimmer — relies on the browser’s built-in decoder, and that decoder refuses all three. It is not a missing feature; it is a licensing and codec-support boundary that no amount of JavaScript gets around.
This page closes that gap the only way it can be closed: the file is converted to WAV on our server, then handed back to your browser, where the trimming, the waveform and the export all happen locally. One upload, then nothing else leaves your machine.
WMA is what Windows Media Player produced for years, so it turns up constantly in old music libraries and in recordings from Windows voice recorders. AIFF is the Apple equivalent of WAV and is what Logic, GarageBand and older Mac software export by default. APE (Monkey’s Audio) shows up in lossless music archives. All three are accepted here.
If your file is already MP3, WAV, FLAC, M4A, AAC, OGG or Opus, use the Audio Trimmer instead — it is faster, it has a fuller editor with fades and multi-region cuts, and it never uploads anything. If you only want to change format rather than trim, the Audio Converter handles that directly.
Because your browser cannot decode WMA, AIFF or APE at all. The Audio Trimmer works entirely offline by handing your file to the browser’s own audio decoder, and that decoder returns an error for these three formats — tested, on valid files that other software opens without complaint. The only way to open them is to convert them somewhere that has the right codecs, which means our server. Once the conversion comes back, everything else — waveform, selection, preview and export — happens in your browser.
WMA, AIFF (and .aif) and APE. Those are the formats worth sending to a server. Everything the browser can already open — MP3, WAV, FLAC, M4A, AAC, OGG and Opus — belongs on the Audio Trimmer instead, where it is faster and nothing is uploaded.
A WAV or an MP3 of just the part you selected. WAV is lossless and larger; MP3 is smaller and lets you pick a bitrate. Because the source has already been decoded to WAV on the server, exporting to WAV adds no further quality loss beyond the original format’s own.
Yes — 200 MB per file, which is the limit on our audio conversion service. A 200 MB WMA is roughly three hours of typical-bitrate audio, so most files are well inside it. Conversion of a large file can take a minute or so; trimming afterwards is instant.
Yes. There is no signup, no watermark and no credit cost for this page. The conversion runs on the same service that powers the free Audio Converter.
It is converted and returned in the same request and is not stored afterwards. If that is still more than you want to share, convert the file yourself with any desktop tool and then use the browser-only Audio Trimmer on the result — that path never uploads anything.
