I built a small web tool to generate “tap the post” / “tap-to-reveal” image slices for X (Twitter): https://splitimage.im/x-image-splitter/

What it does: - Split a single image into templates optimized for X multi-image posts: - 2×2 (4 tiles) - 1×2 (2 strips) - 4×1 (4 vertical strips) - Names files in the correct upload order (e.g., top-left → top-right → bottom-left → bottom-right), so you don’t accidentally post the tiles in the wrong sequence - Runs 100% in your browser (no server uploads)

Why I made it: I kept seeing the “tap the post” pattern on X, where the timeline grid looks cropped/mysterious and the full image is revealed when you open the post. Existing tools either felt too generic (no posting order help) or required uploads. I wanted something quick, local, and harder to mess up.

What I’d love feedback on: - Does the output look correct on X across desktop/mobile for you? - Any edge cases where the crop/reveal doesn’t line up (image ratios, unusual source sizes)? - Feature requests: presets, better previews, bulk mode, or anything else you’d expect from a tool like this.

If you try it and it breaks or feels confusing anywhere, please tell me what you uploaded + which layout you selected (a screenshot of the X preview helps a lot).
