保存之前

  • 请使用不超过 100 MB、500 页且未锁定、无标签的 PDF。不支持数字签名、XFA、含脚本或其他不受支持的文件。原文件不会更改。

Questions about place a signature

Is this digital signing?

This tool places a visual mark only. It does not provide certificate signing, identity verification or an audit trail.

Where is my signature stored?

It stays in this page’s browser memory and in the PDF copy you download. Oxford PDF does not upload or save it.
