About this tool

Choose a PDF, type the word or phrase you are looking for and the tool marks every match with a yellow highlight, tells you how many matches there are and on which pages, and lets you download the highlighted copy. It works on PDFs that have real text; for scans, run OCR first.

Where it is useful

Students mark key terms in lecture notes, lawyers flag a clause across a contract, and anyone reading a long report can highlight a name or a number so that it is easy to find again. The original file is not changed.

Scanned documents

A scanned PDF is only a picture, so there is no text to search. Run the OCR PDF tool first to add a text layer and then use this tool.

Matching

Search is by plain text inside each text run of the page. A phrase that is split across two lines may not be found, so try a shorter part of it. Tick the case box to match capitals exactly.

Privacy

The PDF is processed in your browser and is not uploaded.

獲得最佳結果的提示

開始之前請花一點時間閱讀選項，並先用一個小例子試用工具。一切都在您裝置的瀏覽器中執行；您輸入或新增的任何內容都不會被上傳，關閉標籤頁會清除所有內容。如果看起來不對，請重新整理頁面重試，或使用本頁的報告連結告訴我們出了什麼問題。如果結果仍然看起來不對，請每次只更改一個值，看看哪個輸入影響最大。如果您還會再用，請收藏此頁。
