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.
Gratis · No es necesario registrarse · Tus archivos se mantienen privados
Qué puedes hacer con esto
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.

We put your picture behind the track, draw the waveform if you asked for one, and encode it as an MP4

Preguntas frecuentes
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.

Es un poco molesto que cada vez haya que elegir el tipo de conversión y no se guarde lo que elegí la primera vez. Por lo demás, todo bien.
קצת מעצבן שכל פעם צריך לבחור סוג המרה ולא נשאר מה שבחרתי ראשון חוץ מזה הכל טוב
Impresionante y fácil de usar, gran calidad,
Awesome and easy to use, great quality,
¡Este es un servicio irreal! El sonido es increíble y todas las opciones disponibles lo hacen muy funcional. La estructura de precios basada en minutos convertidos hace que el servicio sea valioso al no "penalizar" la conversión de clips de audio/canciones cortas.
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.
Me encanta este servicio, ¡está hecho tanto para cantantes como para músicos!
Love this service - it’s made for singers and musicians alike!
