Specify by page count, physical size, or a simple scale factor.
Crop marks, registration marks, and per-page labels make gluing or trimming straightforward.
See the effective print DPI before you print, so you know if the result will be sharp.
Frequently asked questions
How do I join the pages together?
In "Overlap & glue" mode, each page includes a duplicated strip along shared edges — trim nothing, just line up the grey-tinted overlap zones and glue there. In "Trim & butt-join" mode, cut along the printed crop marks on each page, then butt the trimmed edges together.
What image size do I need?
The tool shows an effective DPI and quality rating for your chosen poster size. Aim for at least 150 DPI for a good result — if it's rated "blurry", use a larger source image or reduce the number of pages.
Does it work with A3?
Yes — A4, A3, Letter, Legal, and Tabloid are all supported, in portrait or landscape, with an adjustable printer margin.
