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 high-fidelity FLAC audio files into WMA format quickly and efficiently. This tool is perfect for users who need to make their music library compatible with older Windows-based devices or legacy players.
FLAC (Free Lossless Audio Codec) is a container designed for archival-quality audio that preserves every bit of the original source, resulting in large file sizes. WMA (Windows Media Audio) is a proprietary container format developed by Microsoft that utilizes lossy compression algorithms. When you convert FLAC to WMA, the system discards redundant audio data that the human ear typically cannot perceive, effectively compressing the stream to reduce the total disk footprint while maintaining acceptable audio fidelity.
Since you are moving from a lossless format to a lossy one, a portion of the original audio data will be permanently discarded during the conversion process.
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.
