Audio to Video Converter
Create a video from audio plus a still image. Designed for podcasts, music previews, lectures, voice clips, guided meditations, and platform-ready social posts.
Drop Audio File
MP3, AAC, WAV, M4A, OGG
Drop Cover Image
JPG, PNG, WebP
This page is broader than MP3 to MP4. It accepts several audio formats and can export multiple video containers, so it is useful when your source or destination is not fixed. A WAV lecture can become an MP4 with a title slide, an FLAC music demo can become a WebM for a website, and an M4A podcast excerpt can become a vertical social clip with branded artwork.
Choose an audio file, add a JPG, PNG, or WebP image, then select the output video format that matches your platform. MP4 is the safest choice for YouTube and general sharing, WebM is useful for websites, MOV fits Apple workflows, AVI is for older systems, and MKV is a flexible archive container. The image remains visible while the audio plays.
For best results, use artwork that matches the intended aspect ratio. Square graphics work well for feed posts, vertical artwork suits shorts, and 16:9 images fit YouTube-style video. Trim the audio for teasers or quotes, or export the full duration for podcasts, songs, lessons, and announcements.

Who Should Use This Tool
Frequently Asked Questions
What audio formats can I convert to video?
The tool supports MP3, WAV, AAC, M4A, OGG (Vorbis), and FLAC audio files. Most common audio formats are accepted. The audio is decoded and re-encoded into the output video container.
What image formats work for the cover?
JPG, PNG, and WebP images are all supported. For best results, use a square image (1:1 aspect ratio) if targeting Instagram or TikTok, or a 16:9 image for YouTube and landscape video platforms.
What resolution should I choose for the output?
1080p (1920x1080) is the standard for YouTube, Instagram, and most social media. 720p is lighter and faster. 4K (3840x2160) is available for maximum quality but produces larger files and takes longer to process.
Will the video quality of the image be good?
Yes, the tool uses your image at the output resolution. For sharp results, use an image at least as large as your target resolution. The tool will automatically resize larger images to fit without distortion.
Which output format should I choose?
MP4 (H.264) is recommended for universal compatibility. It works on YouTube, Instagram, TikTok, Facebook, Twitter, and virtually every device and player. Choose WebM for open-source preference, or MOV for Apple ecosystem workflows.
How long does it take to generate a video?
Processing time depends on audio duration and output resolution. A 5-minute audio at 1080p typically processes in 10โ30 seconds. Since everything runs locally, your hardware determines the speed. A faster CPU means faster conversion.
Can I trim the audio to create a shorter video?
Yes. Enable the Trim option and enter start and end timecodes (HH:MM:SS). The video will only contain the specified audio segment with the cover image displayed for that exact duration.
Are there any watermarks on the output video?
No. There are no watermarks, no branding, and no limitations. The video you create is yours. Clean, professional, and ready to share anywhere.
