Questions
Why turn audio into a video?
YouTube, Instagram, and X accept videos, not audio files. Holding a cover picture over the sound is the usual way to post music, podcasts, and voice notes there.
Are my files uploaded?
No. Your files are processed on your device. We never upload them.
What format is the video?
MP4 with H.264 video and AAC sound, which YouTube and every phone play. Browsers that can't make H.264 make a WebM (VP9 and Opus) instead; YouTube accepts that too.
Why is the video file so small?
The picture doesn't move, so it's stored once a second and costs almost nothing; most of the file is the sound, at 192 kbps.
What size picture should I use?
Any JPG, PNG, or WebP. The video takes the picture's shape, so a square cover makes a square video and a 16:9 picture fills a YouTube player. It's scaled to fit 1920 (1080p) or 1280 (720p) pixels.
How long does it take?
About as long as the song plays, or less on a computer. Long podcasts on phones take a while; keep the page open.
