About This Launch
Block Poster Maker is a free online tool that turns an image into a giant printable poster. Upload a JPG, PNG or WebP image, choose a paper size, preview the layout, and download a multi-page print-ready PDF to assemble at home. Processing runs in the browser with no upload to a server.
Why I Built This
Built as a privacy-friendly way to make wall art without uploading photos to a third-party server.
