The X (Twitter) header is a wide banner at roughly 1500×500, a 3:1 ratio. The catch is that the profile picture and some text overlap the lower-left corner, and the top and bottom can be trimmed on different screens, so keep important elements centered. This cropper locks the box to 3:1; type 1500 wide and the height follows to 500.
Because the avatar sits over the bottom-left and the banner is cropped differently on mobile and desktop, place logos or text in the middle band and leave breathing room around the edges. Export JPG for a small photo file or PNG for crisp graphics. Crop from a large source so the wide banner stays sharp.
The X (Twitter) header is trickier than it looks because two things move. First, your round profile picture overlaps the lower-left of the banner, so anything placed there is hidden. Second, the banner is cropped differently on mobile and desktop — the visible height changes with screen size, so the top and bottom edges can be trimmed. The safe approach is to keep logos, text and faces in a central band, away from all four edges and clear of the bottom-left. Preview your profile on both a phone and a computer after setting the header to confirm nothing important is clipped.
The header displays at roughly 1500×500, a 3:1 ratio, which this tool locks for you. Export JPG for a small photographic file or PNG for crisp graphics and text; either is accepted. Crop from a high-resolution source so the wide banner stays sharp on large and high-density screens rather than looking soft. If you also maintain other social banners, the Facebook cover and LinkedIn banner croppers preset those sizes, and the crop by size tool lets you type any exact dimensions at the same shape.
The Twitter Header Cropper costs nothing, adds no watermark and asks for no login. Because it works entirely on the HTML canvas in your browser, your images never leave your device, so it is both quick and genuinely private, and it continues to function offline after the first load. It works identically across Windows, macOS, Android and iOS, supports both mouse and touch dragging, and lets you process one image after another without a page refresh. Download as PNG or WebP to retain transparency, or choose JPG for the most compact photo file. The crop frame is locked to the right shape, so every result is consistent without manual measuring.
