Make your X split posts more seamless.
Solve the image gap problem!
On X (formerly Twitter), a widely used technique involves splitting a single image into multiple horizontal slices and posting them simultaneously, creating one large visual on the timeline. It allows impactful tall images to span across the feed, effectively boosting engagement.
X automatically inserts small gaps (margins) between images. With regular splitting, these gaps cause a stretched, disconnected appearance. This tool's "Margin Adjust" mode pre-subtracts the pixels corresponding to these gaps, generating images that connect seamlessly when posted.
Image data is never sent to any server -- everything is processed within your browser. Designed with privacy in mind. Split results can be downloaded individually or bundled as a ZIP file.
