Adobe Reader Lite是非官方的简化版本，因为Adobe Reader是在有点大，很多没用的东西都放在里面，而且安全性也不高，很多朋友都开始用上了国产的Foxit Reader。
PDF (Portable Document Format) 文件格式是电子发行文档的事实上的标准，Adobe Acrobat Reader 是一个查看、阅读和打印 PDF 文件的最佳工具。而且它是免费的。新版增加了两个 Acrobat plugs-ins (Acrobat Search and AutoIndx)，它可以在硬盘、CD 和局域网中搜索用 Acrobat Catalog tool 创建了索引文件的多个 PDF 文件。
