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.

Privacy

Everything runs in your browser, so your data is not uploaded or stored.

獲得最佳結果的提示

請使用檔案的副本進行操作,並在檢查結果之前保留原件。在提交到入口網站、僱主或機構之前,請開啟輸出並檢視每一頁。如果有大小限制,請確認接收網站如何計算:有些把一千位元組算作 1000 位元組,有些算作 1024 位元組。所有處理都在您裝置上的瀏覽器標籤頁中進行,因此大檔案取決於裝置記憶體,在手機上可能需要更長時間。
