Frequently Asked Questions
What is the Audio to Video converter?
This browser-based tool converts your audio files into video by adding a cover image. It takes any common audio format (MP3, WAV, M4A, OGG, FLAC, and more) and runs right in your browser. Perfect for uploading podcasts to YouTube, sharing music on social media, or turning audiobooks into video content.
What do the title, subtitle, and colors do?
When you pick a Style instead of uploading your own image, that Style sets the cover's background colors (gradients like Purple or Ocean, solids like Black or Navy, or a ready-made background). The Title is the large text printed on the cover, and the Subtitle is the smaller line under it (great for an episode number or track name). Both are optional. If you upload your own cover image, the title and subtitle are not used.
What image formats are supported?
You can upload JPEG, PNG, or WebP images. For best results, use high-resolution images. We also offer built-in templates if you don't have a cover image.
Can I create vertical videos for TikTok?
Yes! Choose between horizontal (16:9) for YouTube and presentations, or vertical (9:16) for TikTok, Instagram Reels, and YouTube Shorts.
How long does it take?
Seconds. VideoToBe's Audio to Video tool makes the video right in your browser using your computer's own hardware, so even a long podcast finishes in a few seconds. No upload, no queue, no waiting for an email. The moment it's done you can download the MP4.
Is my audio uploaded to a server?
No. VideoToBe's Audio to Video tool runs entirely in your browser, so your audio and the finished video never leave your device. It takes any common audio format you have, like MP3, WAV, M4A, OGG, and FLAC. That is why it is both instant and private.
What if I don't have a cover image?
No problem! Use our built-in templates with customizable backgrounds, titles, and subtitles. Or create a professional cover using Canva and upload it.
