PiCraft (picraft.ai) turns a short form into finished, correctly sized design files: print PDFs with bleed, transparent PNGs, pure white product photos and thumbnails. We write about file specs and the web tools that export them.
File rules are dull and easy to get wrong. An upload over the size limit is refused, a flyer printed without bleed can show a white edge, and a product photo that is not pure white can be rejected by a marketplace. PiCraft started from those rules: each maker asks only for the details that matter and returns a file at the exact size and format. Every number in our size guides links to the official page it came from.
