On one sheet of A4 this photo prints 27.7 cm wide. Set it By sheets (3 wide × 3 tall) or By size (100 cm wide). Type either side and the other follows the picture, so nothing stretches.
One picture → many sheets
Print a large image on multiple pages
Page Tiles splits one image or PDF page across ordinary sheets: A4, Letter, A3, Tabloid or a size you type. Pick the finished size, check every sheet, then print on the printer you already have.

Scroll to print it02 · Check every sheet
Nine sheets, each one labelled
Switch to Sheets to see exactly what each page will print. Every sheet is labelled in the margin, A1 to C3, with “Sheet 3 of 9”, so a pile of paper goes back together in order. Auto orientation picks the layout with the fewest sheets.
03 · Test the seam
Two sheets before nine
Each sheet can repeat the edge of its neighbour: none, 3, 5 or 10 mm, or your own amount. Cut marks show where to trim. Alignment marks sit at each end of a seam. Print Test Seam… prints A1 and A2 on their own, so you can check the edges before using a whole stack of paper.
04 · Print
On the printer you already have
Print through the normal macOS print panel, or export a PDF with one page per sheet. Print at 100% / Actual Size and the poster comes out the size you set. Smudged B2? Select it and choose Print Only B2.
05 · Trim and join
82.5 × 55 cm, on the wall
Lay the sheets out in label order. Trim the sheet to the right or below along its cut marks, lay it over its neighbour’s overlap and line up the marks. How to assemble a tiled poster.

Before you print
See if your picture is sharp enough at that size
A photo has a fixed number of pixels. Page Tiles calculates the DPI at the finished size and grades it Blurry, Fair, Good or Sharp. How to enlarge without a blurry print.

- Blurry under 100 DPI Soft even from across a room. Go smaller or find a bigger file.
- Fair 100–149 DPI Fine on a wall seen from a few steps back.
- Good 150–299 DPI Looks clean at arm's length.
- Sharp 300+ DPI As sharp as a normal photo print.
- Vector PDF pages PDFs made on a computer print crisp at any size. A scanned PDF is only as sharp as the scan.
Features
Controls for sizing, printing and joining the sheets
By sheets or by size
Choose a grid of sheets, or type the finished width or height in mm, cm or inches. Up to 100 sheets a side.
Auto orientation
Portrait or landscape, whichever needs fewer sheets and wastes less paper. You can still pick one yourself.
Overlap for gluing
Each sheet can repeat the edge of its neighbour: none, 3, 5 or 10 mm, or your own amount. Trim one sheet and glue it over the next.
Cut and alignment marks
Cut marks show where to trim. Alignment marks sit at each end of a seam so neighbouring sheets line up.
Sheet labels
Every sheet is labelled A1, A2, B1 in the margin, with “Sheet 3 of 9”, so a pile of paper goes back together in order.
Test before you print them all
Print Test Seam prints A1 and A2 on their own, so you can check the edges and the overlap before using a whole stack of paper.
Printer margins
Margins start at 1 cm a side. Match a Printer sets them to how close your printer says it can print, and warns you when they’re too narrow.
Reprint one sheet
Smudged B2? Select it and choose Print Only B2, instead of printing the whole poster again.

Honest limits
What Page Tiles doesn't do
Things people ask for that it can't do yet, or won't.
No borderless prints
Most home printers can’t print right to the edge of the paper. Page Tiles leaves a margin and uses overlap to hide the seam.
One page per poster
A multi-page PDF tiles one page at a time. Step to the next page and print again. Your paper, overlap and marks carry over.
No upscaling
Page Tiles prints the pixels you give it. For a small picture, upscale it first, then open the bigger file.
Scans stay scans
Every PDF page gets the Vector grade, scans included. A scanned PDF prints only as sharp as the scan.
100 sheets a side
That’s the most it will lay out. Past it, choose a smaller size or bigger paper.

Common questions
Does it work with my printer?
Page Tiles prints through the standard macOS print panel, so it works with any printer your Mac can already print to. It installs no drivers and needs no printer account.
Can I print without borders?
Most home printers can’t print right to the edge of the paper, so Page Tiles leaves a margin and uses overlap to hide the seam. It doesn’t promise borderless output.
What does it cost?
A one-time purchase on the Mac App Store, which shows the price in your local currency. No subscription and no in-app purchases.
Which Macs does it run on?
Any Mac with macOS 12 Monterey or later, Apple silicon or Intel.
