Its engine is downloaded the first time you run a tool; your files are never uploaded. 1. **Choose a tool and add files**: Pick a tool below, then drop files on the page or choose them from your device. 2. **Your browser does the work**: Everything runs locally on your device. Nothing is uploaded and nothing waits in a queue. 3. **Preview and download**: Check the result, change options and run again. Sign in with a free account to download a file or a ZIP. ## FAQ **How do I extract the audio from a video as MP3?** Use MP4 to MP3, or Video to MP3 for MOV, WebM, MKV and AVI files. The audio track is saved as MP3 at up to 192 kbps; MP4 to MP3 can also save M4A, WAV, FLAC or OGG. **How much smaller does Compress Video make a file?** Compress Video re-encodes the video as H.264 MP4 at up to 1280p. How much smaller it gets depends on the original resolution, length and content; long videos are best compressed on a computer. **Why is video conversion slow on my phone?** FFmpeg runs inside your browser, so the speed depends on your device: a laptop or desktop is much faster than a phone. Keep the tab open until the conversion finishes. **Can I convert WhatsApp or Telegram voice notes to MP3?** Yes. Opus to MP3 converts .opus and .ogg voice notes, and M4A to MP3 handles iPhone voice memos. **Which audio formats are supported?** Audio Converter writes MP3, M4A, WAV, FLAC, AIFF, CAF and OGG, and also reads Opus, AC-3, AU and WMA files. Audio to FLAC turns WAV, AIFF and CAF into lossless FLAC, about half the size of WAV. ## Guides - [How to Reduce Video File Size for Email, WhatsApp and Discord](https://filevale.com/guides/compress-video-file-size/): Make big phone videos small enough to send.
