BannerSplitter

BannerSplitter is for TikTok creators who want a photo or design to span several posts on their profile without cropping each tile by hand. Choose an image, drag it in, or paste it from your clipboard; the browser-based tool supports JPG, PNG, WebP, HEIC, and GIF files up to 20 MB. You can frame the image and split it into three, six, or nine tiles, then check a reassembled preview for seams and warnings about text or faces near the cuts. The numbered tiles download together as a ZIP, ready to post in order. Images are processed in your browser, so they aren’t uploaded, and you don’t need an account or software to install. BannerSplitter also has a video splitter that creates three, six, or nine MP4 posts, plus a 3×3 Instagram grid tool. It may suit creators preparing a profile banner, multi-post mural, or launch and event announcement.
