Yes. MixMasterAI Music to Video AI Generator is completely free and adds no watermark to exported videos. The MP4 you download is clean — just your audio visualizer with the title and artist text you entered. No account required, no file upload, no hidden fees.
MP3, WAV, FLAC, and M4A are all supported. Your browser decodes the audio using the Web Audio API, so the supported formats depend slightly on your browser — Chrome and Edge support all four, Firefox supports MP3/WAV/FLAC. Files up to 50 MB are handled without slowdown.
Three aspect ratios: 9:16 portrait (720×1280) for TikTok, Instagram Reels, and YouTube Shorts; 16:9 landscape (1280×720) for YouTube and Facebook; and 1:1 square (720×720) for Instagram feed and Twitter. All three export at 720p, 30 fps.
You can export a 15-second clip, 30-second clip, 60-second clip, or the full song (up to 120 seconds). For clip modes, the tool auto-finds the most energetic window in your track. Full song export for a 120-second track takes approximately 2-4 minutes to render and encode in-browser.
No. Your audio file is decoded and processed entirely in your browser using the Web Audio API. Video rendering uses the Canvas API and WebCodecs API (H.264 + AAC encoding). No audio, no video frame, and no metadata is sent to any server at any point.
