Media files stay local; diagnostics are separate. Your media file is processed in your browser and is not uploaded or sent to an AI service. If enabled, anonymous diagnostics may be sent, but they do not contain file contents.

Processing Architecture & Calibration

All media streams are isolated locally inside your device using hardware-accelerated WebAssembly (WASM) and WebCodecs. Zero bytes of audio or video content are ever transmitted to external cloud servers.

How It Works

  1. Drop your audio or video file directly into the browser dropzone.
  2. The client-side engine executes local inference or bit-exact extraction without upload delays.
  3. Audition the 15-second realtime A/B comparison with the Dry/Wet slider.
  4. Export your pristine clean master file with 100% original video track preservation.

常见问题解答

这款工具能做什么？
Merge interactive form fields into static read-only vector page content.
它基于什么引擎？
它运行在 Drop & Clean 的本地 WebAssembly PDF 引擎上：解析、重写与导出全部在当前标签页的内存中完成，零服务器往返。
纯端侧 PDF 脱敏是如何彻底消除敏感信息的？
自动将交互式表单域扁平化固化，深度剥离隐藏的 XMP/作者/GPS 元数据、移除可点击外链动作并清除嵌入式附件数据包。
脱敏操作会破坏原文档的排版或清晰度吗？
不会。仅针对深层危险元数据和表单图层进行清洗，原文档的文字矢量排版、字体与图片画质 100% 保持不变。
涉密法律合同或敏感对账单会被上传吗？
PDF 解析、脱敏和重建在浏览器本地运行，文档不会上传。匿名诊断数据可能根据您的隐私设置发送；本地处理本身不代表符合所有保密或法规要求。
