AI 图像超分无损放大 (2x / 4x)
借助端侧 Real-ESRGAN Compact 算法无损放大高达 4 倍,切片 Tiling 架构杜绝显存溢出。
Part of the AI Image Upscaler 4K suite. 100% in-browser private execution with zero cloud storage.
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
- Drop your audio or video file directly into the browser dropzone.
- The client-side engine executes local inference or bit-exact extraction without upload delays.
- Audition the 15-second realtime A/B comparison with the Dry/Wet slider.
- 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。
