BannerSplitter
Free TikTok banner splitter: turn one image into a swipe-through profile banner
A free browser tool that splits one wide image into tiles that line up as a TikTok profile banner, with no watermark, no sign-up and no upload.
About this launch
BannerSplitter is an independent web tool that splits a single wide image into tiles for a TikTok profile banner. Users upload a photo directly in their browser, choose a layout (1×3, 2×3 or 3×3), and the tool cuts it into exact 1080×1440 pixel tiles that line up across the top row of a TikTok profile. The tool runs entirely in the browser—images are never uploaded to a server. It includes seam checks to warn if text or faces cross cut lines, and files are numbered in posting order. BannerSplitter is free with no watermark or account required. A one-time Pro purchase at $9.90 adds batch splitting, custom grids up to 5×5, custom tile sizes and file naming templates.

Shopper questions
What size is a TikTok banner?
A TikTok banner starts from a 3240×1440 px image and splits into three 1080×1440 posts. The profile grid shows each post as 3:4, so these tiles line up exactly.
How do I split a picture into 3 TikTok banners?
Upload the picture, keep the 1×3 layout and frame it. Then download the ZIP file which contains three numbered tiles ready to post. No account is needed.
Does BannerSplitter upload my photo to a server?
No. Your photo is read and cut by your own browser and never sent to a server. Closing the page removes it.
Can I use BannerSplitter for Instagram?
Yes. Instagram's profile grid also uses 3:4 tiles in rows of three, so the same tiles work there when posted in the same number order.
Is BannerSplitter Pro a subscription?
No. Pro is a single payment of $9.90 plus any local tax. There is nothing to cancel.
