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).
