Frequently Asked Questions
此处进行编辑是否会永久删除底层文本？▼
此工具会在您选择的内容上直观地绘制一个实心黑框，这足以在您不希望信息可见的情况下共享文档。它不会从 PDF 的内部文件结构中剥离原始文本，因此对于法律、医疗或高度敏感的文件，请在共享之前将编辑后的 PDF 打印为新的 PDF，从而将其扁平化为纯图像，无需提取任何内容。
Can someone recover the text by copy-pasting over the black box?▼
It's possible with certain PDFs, since the box sits on top of the content rather than removing it from the file's code. If the information is highly sensitive, follow the print-to-PDF step above before you send the file anywhere.
Can I search for a word and redact every instance of it?▼
Yes, type the text you want to hide into the search box, and every matching instance across the document is located so you can mark them for redaction quickly instead of hunting page by page.
我可以编辑整个部分或仅编辑特定单词吗？▼
Both — draw a box over a single word, a paragraph, or an entire block of content, whatever size the sensitive information happens to take up on the page.
当我编辑文档时，我的文档是否已上传到任何地方？▼
不会，整个过程在您的浏览器本地运行，因此您所掩盖的敏感内容永远不会发送到服务器。
