MP3 to MP4 Converter

Combine an MP3 with artwork or a promo image to create a real MP4 video. Useful for music uploads, podcast trailers, audio quotes, lyric snippets, and social previews.

Drop Audio File

Drop Cover Image

Output Size

MP3 works everywhere as audio, but many discovery platforms are video-first. YouTube, TikTok, Instagram, LinkedIn, and short-form channels need a video container even when the content is mainly a song, podcast clip, voiceover, or lecture excerpt. This tool creates that video by pairing the MP3 with a still image.

Upload an MP3 and choose cover art such as album artwork, a podcast tile, a title slide, a waveform graphic, or a branded announcement image. The output is an H.264 MP4 video where the image stays visible for the duration of the audio. Select square, vertical, or landscape-friendly resolutions depending on where the video will be posted.

Use trimming when you only need a teaser, chorus, quote, or preview instead of the full track. Keep the cover image high resolution to avoid blurry output, and choose a format that matches the platform: square for feeds, vertical for shorts, and 16:9 for YouTube-style uploads. The result is ready for posting without opening a timeline editor.

Why Use Our MP3 to MP4 Converter

Share Audio on Video Platforms

YouTube, Instagram, TikTok, and Facebook all require video. Convert your MP3 to MP4 and reach audiences on every platform. Not just audio-only services like Spotify or SoundCloud.

Custom Cover Artwork

Upload any JPG, PNG, or WebP image as your video visual. Album art, podcast episode cover, promotional banner, or custom thumbnail. Whatever represents your audio best.

Multiple Resolution Options

Output at 720p, 1080p, or 4K resolution. 1080p is standard for most platforms. 4K is available for maximum quality when your image and platform support it.

Optional Audio Trimming

Need a video preview instead of the full track? Enable trim mode and select start/end timecodes. Create teaser clips, song previews, or highlight videos from longer audio.

No Watermarks or Limits

Frequently Asked Questions

Why turn an MP3 into MP4?

Many platforms prioritize or require video uploads. MP4 lets an audio track appear on YouTube, TikTok, Instagram, LinkedIn, or other video-first channels with cover art.

What kind of image should I use?

Use cover art that matches the destination aspect ratio: square for feed posts, vertical for shorts, and widescreen for YouTube-style uploads.

Does the image move?

No. The output is a static-image video. The cover image remains visible while the MP3 plays from beginning to end or through the trimmed range.

Can I make a short teaser from a full MP3?

Yes. Trim the MP3 to export a chorus, quote, intro, sample, or promotional clip instead of the complete audio file.

Will the audio still sound like the original MP3?

The audio is placed into a video container using settings suitable for MP4 playback. For normal listening and social uploads, the result should sound very close to the source.

What resolution should I choose?

Use 1080p for most platforms. Choose a vertical or square composition if the artwork is designed for short-form or feed-based social posts.

Is this different from Audio to Video?

Yes. MP3 to MP4 is a focused path for MP3 input and MP4 output. Audio to Video supports more audio inputs and several video output formats.

Can I use podcast cover art?

Yes. Podcast cover art is a common use case. It creates a simple video version of an episode, trailer, quote, or highlight.
