MP3 to Video Converter

Convert an MP3 to video for sites that only take video. Upload your MP3 and pick any 90 seconds or less. Potto adds a waveform, a picture and captions. Then export an MP4.

What an MP3 video is good for

An MP3 cannot go where only video is accepted. A short MP4 can. Here is where the format change helps most.

How to convert MP3 to video

The creator above does the work. Nothing is exported until you say so.

  1. 1. Add your MP3

    Upload the file and a cover image. Say where the clip should start.

  2. 2. Check the clip

    Potto lists the start and the end. Fix them in chat if they are off.

  3. 3. Export the MP4

    Preview the waveform, the picture and the captions. Then export.

What the MP3 to video converter does

A basic converter pairs your MP3 with one still picture. Potto builds a clip. It draws a waveform from your audio and adds your cover image and captions.

  1. 01

    A clip of your MP3

    Say which part to use. Potto lists the clip's start and end. Change them in chat.

    • Files up to 10 minutes

    A waveform, not a still frame

    The shape moves with your sound. Pick bars, a wave or a ring.

    Captions and an SRT file

MP3 to Video FAQs

How it works, limits, formats, captions and credits.

  1. How do I convert MP3 to video?

    Open the creator at the top and drop in your MP3. Add a picture for the cover. Tell Potto where the clip starts. Check the times it lists. When they look right, export the MP4.

  2. What is an MP3 to video converter?

    An MP3 to video converter puts an audio file inside a video file. Many video sites accept video only, so a bare MP3 cannot be posted. A basic converter shows one still picture. Potto's MP3 to video converter adds a moving waveform, a cover picture and captions.

  3. Can I convert a full MP3 to video?

    No. Potto converts one clip, 90 seconds at most. You can upload an MP3 of 10 minutes or less, up to 20 MB. Potto then uses the part you choose. A full-length conversion is not something it does.

  4. Is MP3 to MP4 the same as MP3 to video?

    Yes, in practice. An MP3 holds sound only. Potto's MP3 to video converter writes an MP4, a file with a picture track and your sound. MP4 is the video type most sites and phones accept.

  5. Which audio files can I upload?

    WAV and M4A files are accepted too. Each file can be 10 minutes or 20 MB at most. Your file's sound stays as it is. Potto does not re-record it, remix it or add music.

  6. Can I use my own picture on an MP3 video?

    Yes. Upload a picture along with the MP3. It appears in the frame next to the waveform. A ring style can wrap around it. Potto always draws the waveform, so the result is never a frozen image.

  7. How do I convert an MP3 to a YouTube video?

    Choose 16:9 and export the MP4. Then upload that file to YouTube yourself. Potto does not post for you. Pick the clip that best shows what your audio is about.

  8. Does the converter add captions?

    By default the clip gets captions. They are built from the words in your audio. Save the SRT file if the site you post to takes caption files. Read each line first, because transcripts miss names.

  9. Can I add an MP3 to a video I already have?

    No. You cannot upload an existing video. That rules out adding a soundtrack to your footage. It also rules out pulling an MP3 out of a video. Potto only makes a new video from your audio.

  10. What size is the video?

    The export is an MP4 at 1080p. The default is square, 1:1. Pick 16:9 for a wide player or 9:16 for a phone screen. The frame rate is 30 fps.

  11. Is the MP3 to video converter free?

    You can try it free. Previews cost nothing. New accounts start with 100 credits, which covers 15 seconds. After that, each second of video costs 5 credits, so 30 seconds costs 150 credits.
