纸张必须手动搜索，但数字文档可以立即搜索，对吗？不幸的是，情况并非总是如此。大约25％至33％的PDF文档根本不包含可搜索的信息。例如，当一份扫描件被包装成PDF文档后，您得到了一张文本工具无法访问的图像。
但是，可识别的文本信息的可用性不仅对于搜索或复制文本至关重要。它也是辅助技术如盲人屏幕阅读器的无障碍文件的关键，这已成为政府、公共服务、教育等领域的一项要求。
这些问题的解决方案是光学字符识别。OCR将可见图像转换为编码为文本的信息有关OCR的详细信息）。ABBYY FineReader PDF 中这项技术的优点是它在后台运行，因此在需要时始终可用。因此，如果您打开的文档包含尚不可读信息，FineReader PDF 会在后台执行OCR。
在后台执行的OCR转换是FineReader PDF 的一项独特功能，这使您无需更改文档本身就可以立即访问各种PDF文档。如果文档仅包含扫描件，且该扫描件的一部分是图像，FineReader PDF 使用OCR来查找所有可识别的文本
此功能最大的好处在于，在搜索文档并找到搜索词所有的匹配项之前，您甚至根本不会注意到FineReader PDF 在工作，这是其他PDF工具无法做到的。PDF只是按照您期望的那样工作，并向您展示其工作内容。只有当您使用另一个PDF工具并尝试相同的操作时，才能看到两者的差异。
