About BannerSplitter

BannerSplitter is an independent, independently built web tool for social media creators. It is not affiliated with TikTok.

What it does

It takes one wide image and cuts it into tiles that line up across the top row of your TikTok profile. It numbers the files in the order to post them and checks the result before you publish: whether text crosses a cut, whether something important sits under TikTok's labels, and whether each tile still reads on its own.

How it works

Everything happens in your browser. Your image is never uploaded to a server, and the tool never asks for your TikTok login.
