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

拖入图片压缩到 5MB 以下 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

无需上传服务器，端侧文件压缩是如何在浏览器中运行的？
Drop & Clean 在浏览器中本地压缩图片和视频，媒体文件不会上传。匿名诊断数据根据您的隐私设置单独处理，且不包含媒体内容。
压缩后的照片或视频肉眼可见画质会受损吗？
肉眼几乎察觉不到画质劣化。我们的引擎内置 0.65 智能画质底线保护与多遍码率均衡，在达到目标体积的同时严格抑制噪点色块与严重色阶断层。下载前您还可以直接拖拽对比滑块审验前后画质。
能否将文件精准压缩到平台限制大小（如 Discord、WhatsApp、邮箱附件）？
完全可以。我们为 Discord 免费版（≤10MB / 8MB）、WhatsApp 分享（≤16MB）、Gmail 与 Outlook 邮件附件（≤25MB）以及政务网站表单（≤50KB、≤100KB、≤200KB）提供了经过严格实测的精准字节阈值预设。
支持哪些多媒体文件格式？
全面支持主流媒体格式：包括 JPEG、JPG、PNG、WebP、AVIF 等图片，以及 MP4、MOV、WebM、MKV、AVI、FLV、TS 等视频容器，无需在电脑上安装任何外部转码软件。
处理商业机密文档和个人隐私照片安全吗？
压缩在浏览器本地执行，媒体文件不会上传。匿名诊断数据可能会发送，但不包含媒体内容；详情请参阅隐私政策。
