Shopper questions
What is a TikTok banner splitter?
A TikTok banner splitter cuts one wide image into three equal pieces that you post as three separate photos. When those posts sit side by side in the top row of your profile, they read as one banner. People also call it a banner cutter or a banner divider.
How do I split a banner into 3 for TikTok?
Choose your image, keep the TikTok banner layout selected, and drag or zoom until the preview looks right. Then save the three tiles which are numbered 1st, 2nd and 3rd in posting order.
Which piece do I post first?
Post the right piece first. TikTok shows your newest post first, so post the right piece, then the middle, then the left, and pin them in that same order so the banner stays at the top.
What size should a TikTok banner be?
The recommended size is 3240 × 1440 pixels, which splits into three 1080 × 1440 tiles in the 3:4 shape TikTok uses for profile thumbnails. For full-screen posts, use 3240 × 1920 for 1080 × 1920 pieces.
Is it free and does it have a watermark?
Yes, it is completely free with no watermark, no sign-up required, and no limit on how many banners you can make.
