Bilingual PDF stamping tool — compose seals, check them at real size, export. Fully offline.
PDF Seal Tool stamps your seal image (PNG or JPG) onto a PDF, either as a cross-page seam seal (騎縫章) split across the edges of the pages or as a full seal on every page — no printing and no scanning. Before you stamp, you see your own seal at true size on the page, including the multi-page seam, and you can adjust position, size, offset, opacity, margin and page range; the page range is checked first. There is no page limit, and no license key or activation, so you can carry it on a USB stick. Your contract is processed on your own computer and never uploaded. The interface is available in English and Chinese. Delivered as a digital download. Opens in any modern browser — no install, no account, no internet needed after download.
Anyone sealing contracts who would rather not upload them to an online tool or pay for Acrobat Pro.
所有重要細節,盡在一處。
