## Questions & answers

### Why does my Reel show black bars after resizing?

Scaling a horizontal video into a vertical frame adds bars. To fill the frame edge to edge, crop to 9:16 with the [video cropper](/tools/crop-video-online).

### Does the file get uploaded?

No. Everything runs in your browser, your video never leaves your device, and nothing is stored.

### What size does Instagram Reels use?

The full-screen spec is 1080x1920 at 9:16, applied for you by the Reels preset.

### Need TikTok or Shorts sizing too?

They share the 9:16 spec, so pick the matching preset in the resizer.
