是怎么转换的？会不会只是取出内嵌的预览图？How is it converted — is it just the embedded preview?
不是取预览图。文件在浏览器中用开源的 LibRaw（libraw-wasm 构建，LibRaw 采用 LGPL-2.1/CDDL-1.0 双许可）完整解码：读取传感器原始数据，做去马赛克插值（AHD）、白平衡和相机色彩矩阵转换，输出 8 位 sRGB，再用浏览器编码为 JPG。No. The file is fully decoded in your browser with the open-source LibRaw (the libraw-wasm build; LibRaw is dual-licensed LGPL-2.1 / CDDL-1.0): the raw sensor data is demosaiced (AHD), white-balanced and converted with the camera colour matrix to 8-bit sRGB, then encoded to JPG by the browser.
颜色为什么和相机直出 JPG 或 Lightroom 不一样？Why do colours differ from the camera JPG or Lightroom?
相机直出 JPG 和修图软件会套用各自的照片风格、色调曲线、镜头校正、降噪和锐化；这里只做 LibRaw 的标准解码（含自动亮度），不做镜头校正、降噪或锐化，所以对比度和色彩会有差异，属于正常现象。白平衡默认使用相机记录的数值，也可以改为自动白平衡。The camera's JPG engine and editing apps apply their own picture styles, tone curves, lens corrections, noise reduction and sharpening. This tool does LibRaw's standard decode (with auto brightness) and no lens correction, noise reduction or sharpening, so contrast and colour will differ — that is expected. White balance uses the camera's recorded values by default; you can switch to auto.
为什么比较慢？“半尺寸快速模式”是什么？Why is it slow, and what is half-size mode?
第一次使用时需要下载约 1.5 MB 的解码组件；2000 万像素以上的 RAW 解码通常需要几秒到十几秒。勾选“半尺寸快速模式”后宽和高各减半（像素数为四分之一），速度快很多，适合预览和网络分享。单个文件最大 200 MB，全尺寸输出最大 1 亿像素。The decoder (about 1.5 MB) downloads on first use, and RAWs above 20 MP usually take a few seconds to over ten seconds to decode. Half-size fast mode halves the width and height (a quarter of the pixels) and is much faster — good for previews and sharing. Each file can be up to 200 MB, and full-size output up to 100 MP.
支持哪些相机？EXIF 信息会保留吗？Which cameras work, and is EXIF kept?
支持 LibRaw 能解码的索尼（Sony，含 ARW、SRF、SR2）机型，具体以 LibRaw 支持列表为准；刚发布的新机型或特殊压缩方式可能无法解码，会提示失败。其他品牌的 RAW（CR2、DNG、RW2 等）也可以拖进来转换。输出的 JPG 由浏览器 Canvas 编码，不包含 EXIF（拍摄参数、GPS 等），结果中会显示识别到的相机型号和尺寸。Any Sony (ARW, SRF and SR2) model that LibRaw can decode (see LibRaw's supported-camera list); very new models or unusual compression may fail with a message. RAWs from other brands (CR2, DNG, RW2 …) can be dropped in too. The JPG is encoded by the browser's Canvas and carries no EXIF (shooting data, GPS); the result shows the detected camera and size.
文件会上传吗？Are files uploaded?
不会。ARW 文件在你的浏览器里解码和编码，不会离开你的设备。No. The ARW file is decoded and encoded in your browser and never leaves your device.
