TilePoster: Large Posters

TilePoster helps you create large posters by splitting a photo into a grid and generating a multi-page PDF for printing and assembly. Pick an image, set the grid, then export an A4 or US Letter poster PDF ready to share and print.


Key features

• Choose a photo from your gallery
• Manual grid (2×2 and up) or scale presets
• Multi-page PDF for A4 and US Letter
• Outer margin around the finished poster only
• Overlap between tiles for easier assembly
• Alignment guides: lines / dashed trim / shaded overlap
• Optional row/column tile labels
• Share and print from the Android share sheet

How to use

1. Choose a photo
2. Set the grid, paper size, margin, and overlap
3. Generate the PDF and print it

Tip: Use Actual Size (100%) when printing, and confirm A4 / US Letter in the print dialog.

Create large posters without a large printer — print, then assemble.
