MP3 to MP4 Converter — Free, No Watermark
Turn a track of up to 10 minutes into a video: your picture on screen, an optional moving waveform, and an MP4 that YouTube accepts.

你可以用它做什么
YouTube will not take an audio file. Give it your cover art and get a Full HD MP4 it accepts, with no watermark and no editor to learn.
Take a minute of the episode, add the moving waveform and post it square or vertical — something happens on screen, so the clip stops being a still image.
The picture fills the frame with a blurred copy of itself behind it, so the cover is never cropped, never stretched and never sits in black bars.
工作原理
上传您的文件
We put your picture behind the track, draw the waveform if you asked for one, and encode it as an MP4

常见问题
Is it free, and is there a watermark?
It is free, there is no signup and nothing is written over your video. What you download is your picture, your track and — if you asked for it — the waveform, and nothing else.
Do I need a background image?
No. Without one you get a dark background, which is enough for YouTube and for a podcast clip. Add a picture and it fills the frame: a blurred copy covers the edges and the whole picture sits in the middle, so nothing is cropped away and nothing is stretched.
Which video size should I pick?
16:9 at 1920×1080 for YouTube, 1:1 for a square post in a feed, and 9:16 for Reels, Shorts and TikTok. Pick the one for the place the video is going — reframing later means losing part of the picture.
What does the moving waveform look like?
A wave along the bottom of the frame that moves with the sound, in the colour you choose. It is the strip you see on music channels, and it is the simplest way to show a viewer that the track is playing.
How long can the track be?
Up to 10 minutes. Drawing and encoding video costs many times more than converting audio, so we cap the length to keep the tool free and quick for everybody. For a longer track, cut the part you need first.
Which files can I use?
Any common audio file — MP3, WAV, M4A, FLAC, OGG — and a JPG or PNG for the picture. You get back an MP4 with H.264 video and AAC audio, the combination every player, phone and platform accepts.
Why is the video 25 frames per second?
Nothing on screen moves except the waveform, and 25 frames a second is already smooth for it. A higher rate would only make the file bigger and the render slower, and every platform accepts 25.
Do my files stay private?
Yes. Your track and your picture are processed on our own servers, deleted automatically afterwards and never shown to anyone. The download link is unguessable and is not listed anywhere.

如果你想深入研究一首歌曲中从每种乐器到每段人声编排的细节，vocalremover正是你需要的工具。你可以清晰地听到歌曲中每个组成部分的细节。我平时很少评论，但这次决定在这里写下这段话，因为我想，如果有人看到这里，心中仍有疑虑，需要一些鼓励来尝试使用vocalremover，那就放心地用吧，你绝对不会后悔！！
Si buscás estudiar desde cada uno de los instrumentos hasta cada arreglo vocal de una canción, vocalremover es lo que buscás. Podés escuchar cada componente de tu canción al detalle. No suelo dejar comentarios, pero decidí dejar uno acá porque imagino que si alguien llegó hasta acá y tiene dudas y necesita ánimo para usar vocalremover que lo haga tranquilo, no se va a arrepentir !!

这是一项超乎想象的服务！它的音质令人惊叹，而且所有可用选项都非常实用。基于转换分钟数的价格结构不会 "惩罚 "短音频片段/歌曲的转换，因此这项服务非常有价值。
This is an unreal service! The sound is amazing and all of the available options make it very functional. The price structure being based on minutes converted makes the service valuable by not "penalizing" converting short audio clips/songs.
我喜欢这项服务--它既适合歌手，也适合音乐家！
Love this service - it’s made for singers and musicians alike!
