FAQ
Why convert WAV to MP4 instead of MP3?
Social platforms accept video, not pure audio. Wrapping your track in an MP4 lets you publish to YouTube, Instagram Reels and TikTok while keeping good sound quality.
Can I add a cover image or logo to the video?
Yes. After uploading, click “Advanced settings” → “Artwork” to upload a JPG/PNG. It will fill the canvas behind the animated waveform.
Will the MP4 include an animated waveform?
By default we generate a minimalist bar waveform. You can turn it off or choose a circular or line style in the visual options.
Which resolution and aspect ratio do you export?
The tool outputs 1080 × 1080 px square by default - ideal for feeds. You can switch to 16:9 1080p or 9:16 vertical in the size menu.
Does converting change my audio quality?
The audio is encoded to AAC. Select 320 kbps in Advanced settings for virtually transparent quality, or a lower bitrate for smaller files.
What is the maximum file length or size?
Tracks up to 2 GB or roughly 3 hours are supported. Longer recordings should be trimmed before upload.
How do you protect my privacy?
Files move over encrypted HTTPS, are processed in RAM only and automatically deleted from our servers within minutes of conversion.
