About this tool

Every PDF can hold the author's name, the title, the software used and the date. Remove all of that here; the text and pictures on the pages stay the same.

When to use it

PDFs can hide the author name, the software used and the dates. Remove them before sharing a document publicly.

Tips

Check the result with the PDF Metadata tool. Text in the pages is not changed.

Privacy

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

What counts as metadata

Title, author, subject, keywords, creator program, producer and dates. Some PDFs also carry XMP data, which this tool clears too. The page content is untouched.

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。

要點

常見問題

Will the text or pictures change?

No. Only the file details are removed, nothing on the pages changes.

Are comments and bookmarks removed?

No, they stay. To hide text on the pages use the "Redact PDF" tool.

What details are removed?

Author, title, creator software, keywords and dates.

Does it change the pages?

No. The visible content stays the same.

Can metadata reveal my name?

Yes. Word often stores the author's name, so clean the file before publishing.
