PDF.to wraps your WAV audio into a WMV video with a static cover image (or a generated waveform) as the visual track. Upload the WAV, optionally drop in a cover image, and download the finished WMV.
Why would I convert WAV audio to a WMV video?
+
A WMV video plays everywhere a raw WAV sometimes will not — most notably on video-only platforms and social feeds that require a video container. It is the standard way to publish a podcast, song, or mix as a shareable WMV.
What plays in the picture of the WMV?
+
By default PDF.to shows a single still cover image for the full duration. You can upload your own artwork, or let the converter render an animated waveform that moves with the WAV audio.
Will the audio quality of my WAV change in the WMV?
+
The WAV stream is re-encoded into the WMV container at a high audio bitrate (192 kbps AAC by default), so it stays effectively transparent for music and speech. Lossless WAV sources are not upsampled.
What resolution is the WMV video?
+
The WMV matches the cover image you supply, defaulting to 1280x720. Because the picture is static, a higher resolution adds almost nothing to the file size — the bulk of a WMV made from WAV is the audio.
Can I set a custom thumbnail or cover for the WMV?
+
Yes. Upload any JPG or PNG and PDF.to centers it on a solid background for the whole WMV. This is how you give a WAV track a branded video thumbnail.
Does the WMV keep the title and artist tags from my WAV?
+
Where the WMV container supports metadata, title and artist tags from the WAV are carried over. The cover artwork embedded in the WAV is also used automatically if you do not supply your own.
Can I batch-convert many WAV files to WMV?
+
Yes. Drop a folder of WAV files and each becomes its own WMV video; all of them are zipped for a single download.
Is the WAV to WMV conversion free?
+
Yes, within the free size limit. PRO unlocks much larger WAV uploads, longer durations, and parallel jobs.
How long can the WAV be?
+
Full-length albums and multi-hour WAV recordings convert fine. Because the picture is static, even a long WMV stays modest in size relative to a filmed video of the same length.
Will the WMV play on YouTube, Instagram, and TikTok?
+
Yes. PDF.to encodes the WMV with a widely supported codec and pixel format, so the resulting video uploads cleanly to the major platforms that reject bare WAV audio.
Are my WAV files private during conversion?
+
Uploads are encrypted in transit, the conversion runs in an isolated worker, and both the WAV and the rendered WMV are deleted automatically a short time after you download.
