PDF 里的页面按什么顺序排？In what order do the pages go?

支持哪些图片？会跳过哪些文件？Which images work, and what is skipped?
PNG 和 JPG 直接嵌入；WebP、GIF（第一帧）和 BMP 先在浏览器里解码，再以 PNG 嵌入。每张图片一页，页面大小等于图片尺寸。不是图片的文件和无法解码的图片会跳过，完成提示里会列出它们的文件名；macOS 生成的 __MACOSX 和隐藏文件会忽略。上传的不是 ZIP 或 ZIP 已损坏时会直接提示。PNG and JPG are embedded directly; WebP, GIF (first frame) and BMP are decoded in the browser first and embedded as PNG. Each image becomes one page the size of the image.
