Image grid splitter: turn one design into numbered posts

Prepare a source that survives being divided

Choose a high-resolution JPEG, PNG or WebP. Keep faces, logos and essential text away from tile boundaries. Each exported tile should remain useful when viewed alone, especially if followers encounter individual posts in their feeds. The splitter accepts files up to 24 MB and 24 megapixels to keep processing manageable.

Choose layout and tile shape together

Pick 3×3, 3×4 or 4×4, or choose one to six columns and rows. Select square, 3:4 portrait or 4:5 portrait tiles. Center crop fills the composition by removing excess edges; fit preserves the source within white padding. Preview again after changing any setting, because those choices affect every tile.

Review export order

For a chronological profile where newer posts appear first, bottom-right-first numbering can reconstruct a three-column design after the full sequence is published. For carousel slides, use left-to-right, top-to-bottom order. The downloaded ZIP contains numbered JPEG files and an order guide; downloading does not publish anything.

Check the result before scheduling

Inspect the individual tiles at the size people will see. Exports do not upscale a small source to invent detail. Create separate unscheduled drafts for the selected account directly from the splitter, or download the ZIP and upload tiles to a supported carousel. Add captions and review validation in the publishing editor before scheduling. Native pins, gaps, crops and other posts can interrupt a profile mosaic.
