ToolNova video tools provide audio extraction, format conversion, compression and AI-powered transcription in one hub.
Select a supported video file; the required media engine loads only when you open the tool.
A video extension alone does not determine compatibility; the video and audio codecs inside the container matter too. Knowing what the target device or application accepts reduces unnecessary re-encoding.
| Need | Suggested tool | What to check |
|---|---|---|
| Listen to a video’s audio separately | Video to MP3 | Output quality is limited by the audio track in the source video. |
| Change MP4 and WebM compatibility | MP4 to WebM / WebM to MP4 | Conversion may require re-encoding; duration and output size vary with the source. |
| Turn speech into text | Video to Text | Clear audio, one speaker and correct language selection improve transcription. |
| Reduce file size | Compress Video | A smaller output usually trades away resolution, bitrate or visual detail. |
No. Real compatibility depends on the video and audio codecs as well as the container. Renaming a file does not convert its media streams.
No. Detail missing from the source cannot be recreated. An unnecessarily high setting may only make a larger output.
Some conversion and compression tools use the FFmpeg engine in your browser. AI transcription runs on dedicated server infrastructure; the relevant page discloses the method.
