Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert your OPUS audio files into the uncompressed WAV format effortlessly. This tool is essential for users who need to make highly compressed voice or music recordings compatible with professional editing software.
OPUS is a highly efficient, lossy media container designed for low-latency internet streaming and voice communication. In contrast, WAV is an uncompressed, lossless container that stores raw audio data. When you convert from OPUS to WAV, the compressed data is decoded and mapped into a standard PCM format. Because WAV lacks the aggressive compression algorithms of OPUS, the resulting file size will be significantly larger, often by a factor of 10 or more.
Converting OPUS to WAV does not improve audio fidelity because the original data was already processed with lossy compression. You are simply changing the container format to ensure compatibility.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
