How do I turn a MP3 audio file into a MP4 video?

Upload your MP3 file and the converter wraps the audio into a MP4 video container with a generated visual layer (a solid background or the embedded cover art). The audio plays unchanged; you get a MP4 file you can upload anywhere that requires video instead of audio.

Why would I convert MP3 to MP4 instead of keeping it as audio?

Most video platforms — YouTube, Instagram, TikTok, Facebook — reject raw audio uploads but accept MP4. Converting MP3 to MP4 gives the track a video wrapper so it passes the upload check, while the sound stays exactly as it was in the MP3 source.

What appears on screen in the MP4 file?

By default a static frame: the MP3 file's embedded cover art if present, otherwise a solid background. The frame is held for the full duration of the audio, so the MP4 file is a single still image with your MP3 audio as the soundtrack — small and fast to encode.

Will the MP4 video lose any audio quality versus the MP3 source?

No re-sampling beyond what the MP4 container's audio codec requires. The MP3 audio is muxed into MP4 and, where the container allows the same codec, copied bit-for-bit. Where MP4 needs AAC / Opus, we transcode at 192 kbps or higher so the result is transparent.

How long will the MP4 video be?

Exactly as long as the MP3 audio — a 4-minute song becomes a 4-minute MP4 video, a 50-minute podcast becomes a 50-minute MP4. The still-image visual costs almost nothing, so duration, not picture, drives the encode time.

How big will the MP4 file be compared to the MP3 audio?

Only slightly larger. Because the picture is a single repeated frame, the video stream adds very little — most of the MP4 file size is still the audio. A 5 MB MP3 track typically yields a MP4 file in the 6-9 MB range.

Can I use my own image as the background instead of the cover art?

Not in this one-step converter — it uses the embedded MP3 cover art or a default background. To set a custom still or a looping clip behind the audio, convert MP3 to MP4 here first, then use /video-editor/ to swap the visual track.

Will the MP4 file play on YouTube and social platforms?

Yes. We default to the most compatible codec for the MP4 container (H.264 for MP4 / MOV, VP9 for WebM, H.265 for MKV) so the MP4 upload is accepted and transcoded cleanly by YouTube, Instagram, TikTok and Facebook without a "format not supported" error.

Can I batch-convert a whole album of MP3 files to MP4?

Yes — drop the full set of MP3 files in and each becomes its own MP4 video in parallel. Premium runs more workers, so a 12-track album finishes far faster than converting each MP3 one at a time.

Are my MP3 files private during the MP4 conversion?

Yes — uploaded MP3 files are processed in isolated workers and deleted within minutes. We never listen to, retain, or share your audio. The full retention window is documented at /privacy/.

Does the MP4 video keep the MP3 title and artist tags?

Where the MP4 container supports metadata, the MP3 title / artist / album tags are copied into the MP4 file. Note that most video platforms read their own title field on upload rather than the embedded tag, so set the platform title manually too.

What's the difference between converting MP3 to MP4 and just extracting audio later?

Converting MP3 to MP4 adds a visual layer so the audio can live as a video; the reverse — pulling audio back out of a video — is a separate /video-to-audio/ operation. If you only need the sound in a different audio format, use the audio-to-audio converter instead of going through MP4.
