A CLOSER LOOK
Every sheet, accounted for.
White edges protect the printable area. The repeated image strip helps you line up the next sheet.
Trim edge Shared overlap
A little check. A better print.
Your PDF includes a calibration page, an assembly map
and every poster sheet, in order.
FROM SCREEN TO WALL
Three steps. Zero guesswork.
A ruler, scissors and tape are all you need.
Keep every sheet alike.
Use the selected paper and orientation. Print single-sided. Page 2 is your assembly map; the poster starts on page 3. Keep the same scale for every page.
Match. Trim. Tape.
Lay out the sheets using the map. Trim white edges at the marks. Place each right or lower sheet over the repeated strip on its neighbour. Match the picture and tape on the back. With zero overlap, butt image edges together.
Printer margins vary. Check your printer’s printable area first. Physical printing has not yet been verified on this version.

A few things worth knowing.
Will enlarging my picture make it sharper?
No. Enlarging spreads the same pixels across a bigger area. The effective DPI uses the image’s placed size, including zoom. Below 100 DPI, expect visible pixels; 100–149 DPI can look soft up close. We do not upscale with AI or invent details.
What stays on my device?
Your chosen image, previews, PDF and project are processed locally. There are no image uploads, analytics or accounts inside this tool. Refreshing clears your working image. Save a project before leaving; it contains your image and settings, so treat it like the original image.
Why do some sheets have extra white space?
Exact dimensions do not always fill a complete grid. The final column or row stops at the requested poster edge. “Show whole image” can also leave white space when image and poster proportions differ. Switch to “Fill poster” to crop instead, or choose a page grid to fill the sheet layout.
What are the limits?
Still JPG, PNG and WebP, up to 12 MiB, 16 megapixels and 8,192 pixels per side. Maximum 36 poster sheets, reduced to 25 on small screens or touch devices. A bounded working image (up to 8 MP / 4,096 px; 4 MP / 2,560 px on mobile) keeps memory use manageable. The displayed DPI reflects this working image. Transparent pixels print white. Colours may vary with your printer; this is an RGB home-printing tool.
