TilePrint Lab
Free browser tool

Print an image on multiple pages.

Make a tiled PDF from one JPG, PNG or WebP. Choose the paper, orientation and finished poster width, then adjust the margin and overlap. The preview shows how the picture is distributed across the sheets before you download the PDF.

File and layout limits. Per image: 20 MB, 30 megapixels and 30,000 pixels on either side. Finished width: 5–200 cm (about 1.97–78.74 inches), with up to 36 sheets. The page limit may require a smaller width. Margins: 8–30 mm; overlap: 0–20 mm.

Up to 36 sheets. PDF artwork is rendered at 150 ppi. A 50 mm check line on page 1 helps verify actual-size printing.

A real layout you can inspect

600 by 400 millimetre poster arranged in four columns and two rows of A4 portrait sheets
A4 portrait, 8 mm margin, 5 mm overlap: 4 × 2 = 8 sheets. Auto orientation can choose a different layout.

The 1,200 × 800 pixel sample at 600 × 400 mm contains 50.8 source ppi. Rendering the PDF at 150 ppi does not add missing image detail. Print page 1 at 100% and measure its 50 mm check line.

Set the size before the page count

Choose A4, Letter or A3 in portrait or landscape. The poster width is a physical measurement; its height follows the image proportions. A wider poster usually needs more sheets. Margins reserve space at the paper edge, while overlap repeats a narrow part of the picture on neighbouring sheets to help assembly. Both affect the page count. If the layout exceeds 36 pages, reduce the poster width or change the paper settings.

Before choosing the final dimensions, check the source print size at your chosen PPI.

Check the exported resolution

This browser tool renders PDF artwork at up to 150 pixels per inch to keep memory use manageable. Check the displayed export rendered resolution, especially for a large poster or a small source image. This is not a promise of photographic print quality. Test one sheet at the intended viewing distance before committing paper and ink to the whole poster.

Print and assemble

The PDF includes tile labels to keep the sheets in order. Use the same paper size in the print dialog and select actual size or 100 percent. A fit-to-page setting can change the intended dimensions. Print single-sided, compare adjacent sheets, and trim only the edges needed for your overlap. Input images are limited to 20 MB and 30 megapixels; processing happens in your browser.

If the printed measurement is wrong, follow the steps to print the PDF at actual size.

Once the scale is correct, learn how to trim and join the poster sheets.

Frequently asked questions

Why are some final sheets partly empty?

The chosen physical size may not fill the last row or column of paper. Those sheets contain only the remaining image area; changing margins, overlap, paper or orientation changes the layout.

Does the PDF improve a small image?

No. Rendering at 150 ppi does not recreate detail missing from the source. Check the source ppi at the selected size and print a test sheet.
