CBZ 是什么？What is a CBZ file?
CBZ（Comic Book ZIP）就是把漫画每一页的图片按顺序打包成的 ZIP 文件，只是把扩展名改成 .cbz。转成 PDF 后可以在任何阅读器、平板、Kindle（通过 PDF）或打印机上使用。A CBZ (Comic Book ZIP) is simply a ZIP of the comic's page images in order, renamed to .cbz. As a PDF it works in any reader, on tablets, on Kindle (as PDF) and with printers.
页面顺序是怎么确定的？How is the page order decided?
按压缩包里的完整路径做“自然排序”：数字按数值比较，所以 page2 排在 page10 前面；子文件夹（如按章节分的文件夹）也按名称顺序。__MACOSX、.DS_Store 等系统文件和 txt、xml 等非图片文件会被跳过。Full paths in the archive are sorted naturally — numbers compare by value, so page2 comes before page10 — and sub-folders such as chapters are ordered by name too. System files like __MACOSX and .DS_Store and non-images such as txt or xml are skipped.
支持 CBR 吗？Is CBR supported?
暂不支持。CBR 是 RAR 压缩，浏览器里解压 RAR 需要额外的解码组件；可以先用 7-Zip 等软件把 CBR 解压后重新压缩为 ZIP，再改名为 .cbz。Not yet. CBR uses RAR compression, which needs an extra decoder in the browser. Extract the CBR with 7-Zip or similar, re-compress as ZIP and rename it .cbz.
文件很大会怎样？What about very large comics?
单个文件最大 100 MB、最多 1000 张图片、所有图片合计 6 亿像素以内。默认（自动/无损）模式下，JPEG 页面直接嵌入原始数据，不会二次压缩，PDF 大小和原图接近；带 EXIF 旋转标记、CMYK 或特殊编码的 JPEG 以及 PNG 等其他格式会解码后无损保存。选择“JPEG”压缩时，所有页面按所设质量重新编码。完成提示会说明有几页 JPEG 是原样嵌入的。Up to 100 MB per file, 1,000 images and 600 megapixels in total. In the default (Auto/Lossless) mode, JPEG pages are embedded as is with no recompression, so the PDF stays close to the image size; JPEGs with an EXIF rotation flag, CMYK or unusual coding, and PNG and other formats, are decoded and stored losslessly. With JPEG compression selected, every page is re-encoded at the chosen quality. The done message says how many JPEG pages were embedded as is.
图片会上传吗？Are my images uploaded?
