Convert WMA to M4A Free

The catch with most "free" converters shows up at the end: the download needs an account, a watermark tone is mixed into the audio, or your file waits in a queue behind paying users. None of that applies here. The engine is the same one Pro uses — same speed, same bitrate options — and the output is clean and unmarked.

Free also means free of the usual hidden cost: your file. Many no-cost converters are free precisely because your upload is the product. Here the conversion runs in your browser, so the WMA never leaves your device. Given that WMA files usually come from CDs ripped in Windows Media Player during the 2000s, when it was the Windows default, that's worth more than the price.

Sizes are comparable: WMA and M4A both sit near 1.2–1.2 MB per stereo minute, so this conversion is about compatibility, not storage. You're stacking a second lossy generation. At a generous bitrate that's inaudible, but if you still have a lossless original, encode from that instead: one generation always beats two.

Free covers input files up to 20MB file size limit with a 10-second preview output, and 5 conversions per month. Pro removes those limits for full-length conversions up to 500MB file size limit — and the privacy behaviour is identical, because there was never a server in the loop.

Where does a WMA file even come from? Usually CDs ripped in Windows Media Player during the 2000s, when it was the Windows default. The catch is that WMA has been abandoned — macOS, iPhones, most Android apps, car stereos and smart speakers all skip it. M4A is the destination because it plays essentially everywhere — iPhone Voice Memos and every ordinary phone, browser, and player. Sizes are comparable: WMA and M4A both sit near 1.2–1.2 MB per stereo minute, so this conversion is about compatibility, not storage. Both WMA and M4A are lossy, so this pair stacks a second encode — at a generous bitrate it stays inaudible, but if a lossless original of the WMA exists, encode the M4A from that instead.
