I Built a Browser-Local PDF Redaction Tool Because a Black Rectangle Isn't Redaction

说明与用途

RedactGo 是一个在浏览器本地运行的 PDF 红action 工具，能够永久删除敏感内容，生成可供审阅的新 PDF，并且完全在客户端执行。

问题

A black rectangle can hide text on screen without removing the text stored inside a PDF, allowing the hidden content to be selected, copied, searched, or recovered.

结果

RedactGo removes sensitive text from PDFs locally in the browser, produces a new PDF that can be reviewed before download, and cleans basic metadata and embedded files.

工作流

• Open a PDF up to 10 MB in the browser
• Draw multiple redaction areas across multiple pages
• Undo marks or redact an entire page
• Generate a new PDF
• Review the actual generated output before downloading
• Download the redacted PDF

证据

A black rectangle can hide text on screen without removing the text stored inside a PDF. Someone may still be able to select, copy, search, or recover what appears to be covered.

来源

RedactGo is a free PDF redaction tool that runs locally in the browser.

来源

PDF.js handles viewing, while MuPDF.js runs the redaction work in a background worker.

来源

RedactGo therefore refuses some PDFs with unsupported features, including encrypted files and certain interactive, tagged, layered, or scripted documents.
