Tile Poster

Tile Poster helps you create giant posters by splitting an image into a grid and generating a multi-page PDF you can print and assemble. Choose a photo, set the tile grid, and export a poster PDF for A4 or US Letter—ready to share and print.

■Key Features

•Pick an image from your Photos library

•Choose a grid size (2×2 and up)

•Generate multi-page PDFs for A4 / US Letter

•Outer margin: add margin only around the final poster edges

•Overlap: add a small overlap between tiles for easy assembly

•Alignment guides: lines / dashed trim marks / shaded overlap (optional)

•Tile position labels (Row/Col) (optional)

•Share and print using the iOS share sheet

■How it Works

1.Select an image

2.Adjust grid, paper size, margin, and overlap

3.Generate the PDF and print it

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