Question 1

Does my music get uploaded anywhere?

Accepted Answer

No. Decoding, drawing and rendering all happen inside your browser. Your audio, images and the finished video never reach us or anyone else — there is no server involved.

Question 2

Can I use the videos commercially?

Accepted Answer

Yes. You keep every right to what you load and what you export, and we claim no license over any of it. You do need to hold the rights to the music you use — that part is on you, and since your files never reach us, we could not check it even if we wanted to.

Question 3

What files can I load?

Accepted Answer

Any audio your browser can play — MP3, WAV, M4A and FLAC all work, and OGG does in most browsers. For the background you can add an image or a video, and everything is read straight off your disk, so there is no upload and no size limit beyond what your machine can hold.

Question 4

What do I get out?

Accepted Answer

A 1080p MP4 at 30 frames a second, with H.264 video and AAC audio — the combination every platform and editor accepts. You pick the shape before exporting: 9:16 for Reels, TikTok and Shorts, 1:1 for feed posts, or 16:9 for YouTube. The export is always full resolution no matter how small the preview is on your screen.

Question 5

Which browsers can export?

Accepted Answer

Exporting needs WebGL2 and WebCodecs, including the audio encoder. Chrome and Edge have had it for years, and Safari has it from version 26 on. Older Safari and Firefox can preview but not export. If your browser cannot, the app tells you when you open it rather than after you have done the work.

Question 6

How long does an export take?

Accepted Answer

Usually less time than the track itself. Every frame is drawn and encoded on your own hardware, so a Mac with Apple Silicon or a PC with a modern GPU finishes well ahead of the music, and a recent phone lands roughly level with it. An older machine takes longer. A video background is the one setting that slows things down a lot — a still image or gradient exports far faster.

Question 7

Can I use it on my phone?

Accepted Answer

Yes. It runs in the browser on a phone the same way it does on a desktop, and exports the same 1080p MP4. A phone works through the frames more slowly, and the time scales with the length of the track, so for a full song expect to wait a few minutes. Keep the tab in front and the screen awake until it finishes.

Question 8

What is the difference between free and Pro?

Accepted Answer

Free gives you every visualizer, effect and aspect ratio, exporting up to 30 seconds with a small corner watermark. Pro removes both limits. Nothing is held back from the look itself.

Question 9

What happens if I cancel Pro?

Accepted Answer

Your key keeps working until the end of the period you already paid for, then the free limits return. Nothing you have already exported is affected.
