Post Image Maker

X displays attached images at 16:9 in the timeline, which is why this canvas uses 1600×900 instead of the square or portrait ratios most other platforms default to. A photo shot vertically will lose its top and bottom when it's placed into this frame, so it's worth starting from a landscape source image rather than cropping a portrait one down to fit.

Unlike a Fake Tweet Generator mockup, this is a plain image attachment — no avatar, handle, or engagement counters rendered in, just your background and text composited onto one flat canvas. That makes it the right tool for a quote graphic, an announcement image, or a stat card meant to sit inside a real post's media attachment rather than simulate the post itself.

• •Keep text large and centered rather than tucked in a corner — the timeline crops this image to a shorter preview height before anyone taps to see it full size.
• •A single clear message reads better here than a busy collage, since the image is usually seen for a split second while scrolling before someone decides to stop.
