访问 PDFnoted 网站（pdfnoted.com），拖入待签署的PDF文件；在预览界面勾选需添加签名的页面（如第2页为甲方签字区、第4页为乙方签字区），支持多页同时选中。
点击「添加签名」→ 选择「手绘签名」用鼠标/触控板书写姓名，或「上传图片」导入已签名PNG/JPG（建议白底透明边缘，尺寸≥200×80px）。PDFnoted自动优化边缘清晰度。
将签名拖拽至页面指定位置（如右下角‘签字处’框内），调整大小与旋转角度；点击「批量应用到选中页」，PDFnoted自动在所有已选页面相同坐标处插入签名，确保格式统一。
确认所有签名位置无误后，点击右上角「下载PDF」按钮，PDFnoted生成含嵌入式签名的不可编辑PDF（符合ISO 32000标准），支持直接发送给客户或归档使用。
Go to pdfnoted.com, drag & drop your PDF. In the preview pane, check the pages where signatures are needed (e.g., page 2 for Party A, page 4 for Party B)—select multiple pages at once.
Click 'Add Signature' → choose 'Draw Signature' to write your name with mouse/touchpad, or 'Upload Image' to import a PNG/JPG of your signed name (white background + transparent edges, min. 200×80px). PDFnoted auto-sharpens edges.
Drag the signature to the exact spot (e.g., inside the 'Signature Here' box), resize or rotate as needed. Click 'Apply to Selected Pages'—PDFnoted places identical signatures at the same coordinates on every selected page.
Once verified, click 'Download PDF' in the top-right corner. PDFnoted outputs a standards-compliant, non-editable PDF with embedded signatures (ISO 32000), ready for email or archival.
PDFnoted生成的签名属于可视化电子签名（Visual E-Signature），适用于日常商务场景（如内部审批、服务协议）。如需具备《电子签名法》第十三条规定的‘可靠电子签名’效力，建议配合身份认证与时间戳服务（PDFnoted暂不内置，但输出格式兼容第三方CA集成）。
可以。PDFnoted支持添加多个签名模板（如‘张经理’‘李总监’），每套签名可独立绘制/上传，并分别拖放到对应页面或区域。操作时只需重复步骤2–3，系统自动保存各签名实例。
PDFnoted导出的PDF默认禁用编辑权限（含表单填写、内容修改），且签名图像以矢量+栅格混合方式嵌入，无法被常规PDF工具删除或移动。如需更强保护，可在下载后用PDFnoted的‘密码加密’功能设置打开密码。
PDFnoted creates visual e-signatures—suitable for internal approvals and standard agreements. For legally enforceable 'qualified electronic signatures' (per China’s E-Signature Law Art. 13), pair with external identity verification & timestamping services (PDFnoted outputs compliant PDFs but doesn’t host CA integration).
Yes. PDFnoted allows multiple signature templates (e.g., 'Manager Zhang', 'Director Li'). Create each via 'Add Signature', then drag distinct signatures to their designated pages/areas—each is saved separately and reusable.
Exported PDFs are read-only by default—no form filling or content editing allowed. Signatures embed as vector + raster layers, resisting removal/movement in standard PDF tools. For extra security, apply password protection via PDFnoted’s 'Encrypt PDF' option before download.
