Poster tools
Poster tools here turn a picture into something you can print large: a raster wall, a tiled PDF, or a designed poster. A general design suite is included only where people already use it as the alternative.
Print size and bleed are the real difference, and most vendor sites hide them behind the editor. The table can tell you whether the tool is free, in the browser, or open source. It cannot tell you the largest poster it will export. Open the product before you promise a print size.
