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 uncompressed WAV audio files to the highly efficient FLAC format. This tool is ideal for audiophiles and archivists looking to reduce storage space without compromising sound fidelity.
WAV is a raw, uncompressed media container that stores audio data in a linear pulse-code modulation (LPCM) format, resulting in very large file sizes. FLAC (Free Lossless Audio Codec) is also a media container, but it utilizes sophisticated compression algorithms to shrink the data footprint while maintaining bit-perfect reproduction of the original signal. When you convert WAV to FLAC, you are essentially wrapping the original audio stream into a more efficient, metadata-rich container.
Since both WAV and FLAC are lossless formats, the conversion process preserves the original audio quality 100%. You lose no data; the sound remains identical to the source.
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.
