About this tool

Check what a PDF says about itself: title, author, the program that made it, when it was created and changed, the number of pages and the page size in points and millimetres. It is a quick way to check a file before you share it. To remove this information use the Remove Metadata tool.

When to use it

See the author, title, creation date, software and page size stored inside a PDF, for checking where a file came from or before you share it.

Tips

Use Remove Metadata to clear the details. Page size shown here helps when a form asks for A4 or Letter.

获得最佳结果的提示

请使用文件的副本进行操作，并在检查结果之前保留原件。在提交到门户网站、雇主或机构之前，请打开输出并查看每一页。如果有大小限制，请确认接收网站如何计算：有些把一千字节算作 1000 字节，有些算作 1024 字节。所有处理都在您设备上的浏览器标签页中进行，因此大文件取决于设备内存，在手机上可能需要更长时间。
