RepostGrid

RepostGrid is a free tool for making TikTok profile banners. TikTok shows the top row of pinned or recent posts side by side, so a wide image split into three tiles can read as one banner across your profile. RepostGrid takes one image and cuts it into a 3-tile banner or a 3x3 grid, with a preview of how it will line up and the correct order to post the pieces. Everything runs locally in your browser, so your image is never uploaded to a server. There is no sign-up and no watermark on the exported tiles. You can download each tile separately or all at once. It is handy for launches, rebrands, event announcements, or anyone who wants a tidy profile without opening a design app.
