Yes for outputs up to 6000 pixels on the longer side, with a caveat on the cell-size scaling. The export honours the source resolution of the cutout, so a 4000-pixel-wide cutout produces a 4000-pixel-wide composite with the checker rendered at full pixel sharpness across the entire grid — print this at 300 DPI and you get a clean 13-inch-wide canvas, at 200 DPI you get a 20-inch banner, at 150 DPI you get a 26-inch wall print. The caveat is that the auto-fit cell ratio is calibrated for screen viewing, where 14 to 18 cells across the subject reads as a deliberate backdrop. At wall-art scale, that same ratio can read as too coarse; consider overriding manually to the fine cell-size preset for wall prints over 24 inches wide. The /commercial-use-background-remover/ documentation covers the licensing for canvas-print resale, which is permitted on every export from this tool.

Yes, and that is the most common use of this look. The grey-and-white checker (RGB 204,204,204 over RGB 255,255,255 is the common default) is the universal visual shorthand for transparent in graphic-design tutorials, portfolio mockups, transparent-PNG demonstration shots and editorial articles about cutouts. Sometimes the writer wants to show what a transparent file looks like without shipping a transparent PNG, because the publishing platform may flatten it, or the article must render the same way in dark mode and light mode. To do that here, put your own grey-and-white checker image behind the cutout and download a JPG: the checker is flattened into the picture, so it shows the idea of transparency without being transparent. If you want a genuinely transparent PNG instead, keep the background transparent and download a PNG — the same file our /transparent-background/ tool makes.
