关于此工具
选择区域或文字匹配项。本地引擎会永久移除所选文字、重叠的图像像素及相交的图形，再填充纯色。除非将所有页面栅格化，其他文字仍可选取。模糊和马赛克不用于永久删改。
新文件会清除旧版本、未使用对象、元数据、附件、书签、批注、链接和表单，并使数字签名失效。画笔可能移除附近内容。搜索仅查找可提取的文字，不执行 OCR，也不跨行匹配；扫描件应手动选择区域。未选中的副本可能保留。分享前请检查下载文件的每一页。

常见问题

This tool works with text-based PDFs. For scanned documents, you would need to use manual area-based redaction.
Yes, you can set the redaction color, add borders, and optionally include replacement text like "[REDACTED]".
Enable "Use Regular Expression" to search using regex patterns. For example, \d{4}-\d{4}-\d{4}-\d{4} to find credit card numbers.
