Three square-aware local grid slices and an order reminder.
Aftermath creates image files only. It does not connect to Instagram or publish content.
Selected files are processed in the current browser session. Aftermath has no account, cloud file storage, or server-side file-processing job.
Create a three-column image grid locally when one wide design needs to become ordered Instagram-style slices. The tool packages the slices in a ZIP and preserves their intended order for review. Platform presentation can change, so inspect the actual profile layout and current Instagram guidance before relying on a grid for publication.
A wide campaign image should become three ordered square profile-grid posts without reversing their posting sequence.
Observed operation: Fit the source to the three-panel grid, split it into ordered slices and download the numbered ZIP locally.
Review the result: Preview the three panels together and verify the documented posting order before uploading any slice.
Boundary: The route does not control a social profile layout, platform crop, posting sequence after download or future display behavior.
The selected image stays in the current browser session and is not sent to an Aftermath processing service. How local processing is verified.
Checks the displayed limits and reports or creates a ZIP containing three ordered Instagram grid slices from one supported local image.
A local measurement or export does not guarantee acceptance by an external destination.
