A free Chinese-language tool for creating and placing digital seals on PDFs, with seam stamps, watermarks, invoice merging, and scan cleanup.

Why it surfaced

盖章通 handles the unusually specific mechanics of Chinese document workflows: it splits a seal across page edges so a multi-page seam stamp reconstructs as one image, and it can arrange invoice images and PDFs into an A4 document. The site says files stay in the browser, with no registration, usage limit, or export watermark.
