The TikTok look

Blurred-background fill keeps the whole frame visible (nothing important cropped away), or crop-to-fill for a full-bleed vertical — your choice, positioned your way.

Runs on your hardware

Where your browser supports it (Chrome/Edge/Safari), the work runs on your device's video hardware via WebCodecs — far faster than uploading to a server and waiting in a queue.

Free, no watermark, no caps

No account, no watermark, no length or file-size tiers, no daily limit. The things other video sites paywall are simply free here.

How to do it

  1. 1Drop your video in — 9:16 is preselected.
  2. 2Pick blurred-background or crop-to-fill and position it.
  3. 3Trim to length and export the MP4.

FAQ

What aspect ratio is TikTok?

9:16 vertical — 1080×1920. This page preloads that format; you just choose how to fill the frame.

How do I make a landscape video fit TikTok without cropping?

Use the blurred-background fill: the full landscape frame sits centered over a blurred cover — the standard look you see all over TikTok.

Will there be a watermark?

No watermark — the export is clean MP4, ready to post.
