The Twitter / X timeline crops in-feed image previews to a 16:9 aspect ratio. If key visual elements or text overlays sit outside this viewing window, users see an awkward, uninformative preview card.
Our converter formats graphics to 1200×675 pixels, ensuring the focal point sits right in the center of the timeline preview card. This helps drive higher retweets, likes, and click-through rates.
Designed for news outlets, indie developers, marketing professionals, and digital artists who want their shared images to display cleanly on the timeline.
