PDF 页面签署常见问题
这个签名工具免费吗？

这是具有法律效力的电子签名吗？
该工具放置的是视觉签名。法律效力取决于您的司法辖区和流程；请查阅当地要求以获得合规的电子签名。
签署大PDF速度快吗？
字段放置和保存均在本地完成，因此即使多个字段的大型PDF也能在几秒内完成签署。
Can I keep signing without connectivity once everything is loaded?
Yes. After the signer, your PDF, and any signature assets are cached in your browser, you can keep placing fields and exporting even if your connection drops. Reconnect before sharing the finished file so teammates can download it.
How do I route the PDF to additional signers without overwriting earlier marks?
Follow the how-to flow: let the first signer place their fields, press Sign & Download to export a copy, then share that file with the next signer. Each person opens the latest export, adds their marks, and repeats the export-share cycle so every signature stays intact.
