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

拖入图片即可 4x 无损放大，细节更清晰 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.

纯端侧 AI 图像超分与画质修复是如何运作的？
Drop & Clean 使用 WebGPU 与 WebAssembly 在浏览器中运行 Real-ESRGAN Compact。图片在本地处理，不会上传；匿名诊断数据可能会发送，但不包含媒体内容。
放大 4K 等超大图片会导致显存溢出或浏览器崩溃吗？
不会。系统内置动态 Tiling 切片引擎，将大图分拆为 256x256 单元切片与余弦加权融合，在任意配置的电脑上均能平稳运行，杜绝内存爆满。
我的个人照片和商业设计图是否安全？
图片增强在浏览器本地运行，图片不会上传。匿名诊断数据根据您的隐私设置单独处理，且不包含图片内容。
