Which video sizes does the resizer export?

The tool exports 1080×1920 for 9:16, 1080×1350 for 4:5, 1080×1080 for 1:1, and 1920×1080 for 16:9.

What is the difference between crop and contain?

Crop fills the selected frame and may remove content from the edges. Contain keeps the full source frame and adds empty space when the aspect ratios differ.

Is my video uploaded to Videotok?

No. This free resizer uses browser media APIs to process and export the video on your device.
