Frequently Asked Questions
Can this tool hack or bypass a password I've forgotten?▼
不可以。如果 PDF 有“用户”加密，这意味着它需要密码才能打开它，您需要知道该密码。如果它只有“所有者”限制，例如阻止打印或复制，则通常可以在没有任何密码的情况下将其删除。
在这里解锁银行对账单或税务文件安全吗？▼
是的，解密发生在您的浏览器本地 - 您输入的密码和文档本身永远不会发送到我们的服务器。
所有者和用户限制有什么区别？▼
User-level encryption locks the file so nobody can open it at all without the password. Owner-level restrictions let anyone open and read the file, but block specific actions like printing, editing, or copying text.
解锁会改变我的 PDF 中的其他内容吗？▼
No, the content, formatting, and page order stay exactly the same — only the password requirement and permission locks are removed.
Can I re-lock the PDF later if I need to?▼
是的，解锁后，您可以随时通过“保护 PDF”运行它，将新密码重新添加到文件中。
