Adobe Reader（也称为Acrobat Reader）是美国Adobe公司开发的一款优秀的PDF文档阅读软件。文档的撰写者可以向任何人分发自己制作（通过Adobe Acobat制作）的PDF文档而不用担心被恶意篡改。

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。
