🎵 Convert audio
Convert audio to another format. Supports common formats including MP3, WAV, OGG, AAC, FLAC, M4A and OPUS.
🎬 Convert video
Convert video to another format. Supports common formats including MP4, WebM, AVI, MOV, MKV and FLV.
Choose a conversion based on what you need to keep
Decide whether you need sound, video or both. Format conversion creates a compatible output; it does not automatically repair distortion, remove noise or restore source detail.
| Your task | Tool to use | Output and checks |
| A player does not accept the recording format | Audio conversion | Try MP3. Check the duration and the beginning and end, then play the result on the target device. |
| A video will not open and needs another format | Video conversion | Try MP4. Compatibility also depends on codecs and devices. Check the picture, sound and synchronization. |
| You only need the speech from a recording | Extract audio from video | Output contains audio only, and the original video must have an audio track. This does not transcribe speech or isolate voices. |
Which quality setting should I choose?
MP3/AAC/M4A target 96, 192 or 320 kbps; Opus targets 96, 192 or 256 kbps; OGG uses quality 3, 6 or 9 with a bitrate that varies by content. WAV/FLAC do not use lossy presets. Higher settings cannot recover lost detail and may produce larger files.
Video presets depend on the encoder. H.264 in MP4/MOV/MKV and VP9 in WebM use CRF 35/23/18; AVI/FLV use quantizer values 12/5/2. Lower values usually mean higher quality and larger files. Results vary by codec and source. High quality does not increase source resolution, and conversion does not guarantee a smaller file.
Example: keep only the sound from a meeting video
- Play the original and confirm it contains the audio you need.
- Open audio extraction and try MP3 with medium quality first.
- Follow the task status after submitting. Download the completed result and listen to the beginning, middle and end.
- If audio is missing or the wrong track is selected, check the source. This tool does not offer manual selection among multiple audio tracks; use software with that capability if needed.
