Platform documentation & further reading:

Keep the important content central

Leave space for captions and controls around the main subject. Check the image in the editor or publishing screen where you will use it, since overlays can cover different areas.

Check the cover options before publishing

TikTok Help describes selecting a frame from the video before posting. This tool only saves a still JPEG; it does not set your video cover. Check your publishing app before preparing a separate image. The help page does not specify 1080 × 1920 as a required cover size.

Frequently asked questions

Will this add a custom cover to my TikTok video?

No. It saves a still image to your device. Check whether your publishing app lets you use that image as a cover, and preview the result before publishing.

What size does this preset export?

It exports 1080 × 1920 at 9:16. This is a KiiMix preset, rather than a required size for every TikTok cover. Advertising formats have their own specifications.

Can I crop a video here?

This tool processes image files only. It does not edit a video timeline or extract a frame from a video.
