About X (Twitter) Post Image Maker
On X (formerly Twitter), posts move fast and images are what make people stop scrolling. A well-made image attached to a post gets far more attention than plain text, and a clean profile header signals that an account is worth following. This maker covers the two sizes that matter most: the in-stream post image at 1600×900 (16:9), which displays crisply without awkward cropping, and the profile header at 1500×500. Add a bold headline with an outline and you have a graphic that reads clearly even as a small preview in a busy timeline.
Post image vs header
Use 1600×900 for images you attach to posts — X previews landscape 16:9 images nicely and they expand cleanly on click. Use 1500×500 for your profile header (banner); note that on many screens the top and bottom edges of the header get cropped and your profile picture covers the lower-left corner, so keep key text centered and clear of that corner. Both presets are one tap away at the top of this tool.
Keep it readable
Short beats long: a few large words with strong contrast outperform a paragraph squeezed into an image. Use the outline or a dark overlay so text survives over photos. As always, everything is processed locally and nothing is uploaded.
