A real WebM video file whose audio track is your M4A, paired with a generated visual — a still background, the cover art, or a rendered waveform. Nothing is invented: the audio is untouched, and the picture exists only because a video container needs a video stream.

Only if the container requires it.

Where it does not, we re-encode once at a high bitrate — audible difference is very unlikely.

Duration is limited by the file-size cap rather than by minutes. A static-image WebM adds very little per minute on top of the audio, so full-length podcast episodes and DJ sets convert comfortably; free accounts cover typical uploads and Pro raises the ceiling.

MP4 with H.264 and AAC is the universally-safe combination and what we default to. Because WebM ní àwọn ààyè-iṣẹ́ wẹ́ẹ̀bù tí a kò fi ẹ̀yàn-ìdáràn-ìpàdé - vidéòlù VP9 tàbí AV1 láti ní ìrànwọ́ Opus, tí a fi àwọn àmì-ìwé ìṣàfarawé kọ́òdù nípa àwọn ìṣàmúlò-ètò gbogbò tí a tí wa, the container you pick determines where it plays more than the audio ever does.
Tags are copied into the WebM container metadata where there is an equivalent field. Note that platforms usually ignore embedded video metadata and use the title and description you type into their own upload form.
Can I convert a batch of M4A files into videos?
+
Yes — upload several and each becomes its own WebM with the same visual settings. This is how people turn a full album or a season of episodes into uploadable videos in one pass.
