立即使用电子签名 → Use E-Sign →

1. 上传或创建签名

打开 PDFnoted（无需安装），点击「电子签名」按钮 → 选择「手绘签名」用鼠标/触控板自由绘制，或「上传图片」导入已保存的签名PNG/JPG文件（建议透明背景、尺寸适中）。PDFnoted 自动优化边缘清晰度。

2. 导入并定位 PDF 文件

点击「上传PDF」，选择待签署文档；加载完成后，使用底部页码栏跳转至需签名的页面（如第3页合同签字栏）。PDFnoted 支持缩放与平移，确保精确定位。

3. 拖放签名并调整大小

将签名图标拖入PDF页面指定位置；按住右下角圆点可自由缩放，旋转图标可微调角度（支持±30°），松手即固定。支持多签名——重复操作即可为联合签署人添加多个签名。

4. 导出签署后的 PDF

确认位置无误后，点击右上角「下载PDF」按钮，PDFnoted 将生成含嵌入式签名的新文件（非图片浮层，文字仍可选中、搜索）。文件自动保存至本地，全程不上传服务器。

1. Upload or Draw Your Signature

Open PDFnoted (no install needed), click ‘E-Sign’, then choose ‘Draw Signature’ to sketch freely with mouse/touchpad—or ‘Upload Image’ to import a PNG/JPG signature file (transparent background recommended). PDFnoted auto-enhances edge clarity.

2. Import Your PDF and Navigate to Target Page

Click ‘Upload PDF’ and select your document. Once loaded, use the bottom page navigator to go to the target page (e.g., page 3’s signature field). Zoom and pan freely in PDFnoted for pixel-perfect placement.

3. Drag, Resize & Rotate Your Signature

Drag the signature icon onto the exact spot on the PDF page. Resize by dragging the bottom-right handle; rotate ±30° for fine alignment. Release to lock. Add multiple signatures for co-signers—just repeat the process.

4. Export Your Signed PDF Instantly

Once positioned correctly, click ‘Download PDF’ (top-right). PDFnoted embeds your signature as vector-based markup—not an image overlay—so text remains selectable and searchable. The signed PDF saves locally; zero upload occurs.

小贴士：✅ 建议提前用白纸黑笔手写签名拍照，裁切留白后保存为PNG（透明背景）→ 上传后更易对齐；❌ 避免在签名区域叠加文字框，可能遮挡签名；💡 按Ctrl+Z随时撤销误操作。

Tips: ✅ Pro tip: Scan your handwritten signature on white paper with black ink, crop tightly, save as transparent PNG—uploads align more precisely. ❌ Avoid placing text boxes over signature areas. 💡 Press Ctrl+Z anytime to undo.

常见问题

FAQ

手绘签名会模糊或失真吗？

不会。PDFnoted 使用矢量描边技术绘制签名，无论放大多少倍都保持锐利；导出时自动转为PDF原生路径对象，完全不失真。

能给多页PDF每页都加不同签名吗？

可以。PDFnoted 支持逐页编辑：切换页面后重新拖入签名，每个签名独立定位、缩放和旋转，适合律师函、分页审批表等复杂场景。

签名后还能编辑文本或添加其他注释吗？

可以。PDFnoted 是全功能PDF标注工具：签名后仍可高亮、批注、添加文本框或形状，所有操作实时保存，支持撤销/重做。

Will my hand-drawn signature appear blurry or distorted?

No. PDFnoted renders signatures as vector paths—not raster images—so they stay crisp at any zoom level. Exported signatures become native PDF path objects, ensuring perfect fidelity.

Can I place different signatures on different pages?

Yes. PDFnoted allows per-page editing: switch pages and drop unique signatures each time—each independently resizable, rotatable, and positionable—ideal for multi-page legal docs or approval workflows.

Can I edit text or add other annotations after signing?

Yes. PDFnoted is a full-featured annotation suite: after signing, you can highlight text, add comments, insert text boxes or shapes—and all edits are non-destructive with full undo/redo support.
