WAV (.wav) · Max 20 MB

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 WAV never leaves your device. Given that WAV files usually come from recording sessions, DAW bounces, and anything captured uncompressed, that's worth more than the price.

WAV costs you around 10 MB for every minute; Opus asks for about 0.5. Over a long recording that gap is the whole reason to convert. Starting from WAV means the encoder isn't working around someone else's compression. That's why this produces a better Opus than converting from an already-lossy file would.

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.

Most people meet WAV through recording sessions. It is a fine format there; the trouble is that WAV is uncompressed, so files are enormous — an hour of audio runs past 600 MB. Opus is the destination because it plays essentially everywhere — Discord recordings and every ordinary phone, browser, and player. WAV costs you around 10 MB for every minute; Opus asks for about 0.5. Over a long recording that gap is the whole reason to convert. Because WAV is uncompressed, encoding to Opus here is the clean, single-generation case — the encoder sees the whole original signal, so this Opus is as good as the format gets.

Frequently Asked Questions

Is this WAV to Opus converter really free?

Yes — no watermark, no signup, no queue. Free covers files up to 20MB file size limit, 5 conversions per month, and a 10-second preview output. Pro removes those caps; the engine and audio quality are identical on both tiers.

What's the catch with free converters?

Usually one of four: a watermark tone in the audio, a forced account before download, a throttled queue behind paying users, or your file quietly becoming the product on someone's server. None apply here, because the conversion never leaves your machine.

Do I need an account to download the Opus file?

No. The file downloads straight from your browser the moment conversion finishes — it never went anywhere, so there's nothing to gate behind a login.

Is the free output lower quality?

No. Free and Pro use the same encoder and the same bitrate options. Quality is never the paywall — the free tier limits length and file size, not fidelity.

How much smaller or larger will the file be?

WAV costs you around 10 MB for every minute; Opus asks for about 0.5. Over a long recording that gap is the whole reason to convert.
