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 MP4 video files into OGG audio format quickly and efficiently. This tool is ideal for users who need to extract audio tracks from video clips for specialized media players or web applications.
MP4 is a versatile multimedia container primarily designed for video storage, while OGG is a flexible open-source container optimized for audio streams. During this conversion, the tool strips away the video track and re-encodes the audio stream into the OGG container. This process transforms a video-based file into an audio-only format, ensuring compatibility with platforms that prefer the Vorbis or Opus codecs housed within OGG.
Since both MP4 and OGG are lossy formats, re-encoding the audio stream will lead to a minor generational loss in quality. The file size typically remains relatively stable, as you are simply removing the heavy video data and retaining the audio data.
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.
