常见问题

FAQ

PDFnoted能破解所有类型的PDF密码吗？

PDFnoted专精于移除「打开密码（Document Open Password）」，即限制打开文件的密码；不支持移除权限密码（如禁止编辑/打印）。该设计符合安全合规要求。

去除密码后，原文档格式和字体会不会变形？

不会。PDFnoted采用原生PDF解析引擎，不转码、不OCR，直接重建文档对象树，100%保留原始字体嵌入、矢量图形与页面流，格式零失真。

处理过程是否上传到云端？我的文件安全吗？

PDFnoted在浏览器内完成全部处理（WebAssembly技术），文件全程不上传服务器；任务结束后自动清除内存缓存，隐私零留存，符合GDPR与企业级数据合规标准。

Can PDFnoted crack all types of PDF passwords?

PDFnoted only removes Document Open Passwords (required to open the file). It does not bypass permission passwords (e.g., edit/print restrictions)—ensuring compliance with PDF security standards.

Will fonts or layout change after password removal?

No. PDFnoted uses native PDF parsing—no OCR or re-rendering—reconstructing the object tree directly. Fonts, vectors, and page flow remain identical to the original.

Is my file uploaded to the cloud? Is it secure?

All processing happens client-side via WebAssembly—your file never leaves your browser. Memory is wiped post-task, ensuring zero data retention and full GDPR/compliance alignment.
