The outline shows the crop or fitted picture. Shaded bands are rough layout guides for vertical output, not official safe-zone dimensions. Actual controls vary by device, captions and player state; check the upload preview.
Do the crop on your phone
Cropzen crops, trims and resizes video to these ratios on Android. No watermark or sign-up. 1080p exports are free; Pro adds 4K.
What to watch out for on TikTok
- The bottom 480 pixels are the riskiest real estate on any platform. Nothing readable belongs there.
- Captions added inside TikTok land in the same zone, so plan for them instead of fighting them.
- Exporting above 1080p rarely survives compression in any visible way.
