Frequently asked questions

Which ratio do I need for TikTok, Reels or Shorts?

9:16 (portrait). Instagram feed posts use 1:1 or 4:5, YouTube and most TVs 16:9.

Is there a file size limit?

No fixed limit. The video is read in small slices and the result is streamed to your disk, so even multi-gigabyte files work without filling up memory.

Is my video uploaded to a server?

No. The file is read and written inside your browser tab using WebCodecs — nothing is uploaded, there is no account and no watermark. Once loaded, the page also works offline.
