PDFs, or Portable Document Format files, are commonly used for sharing documents online. PDFs are popular because they preserve the formatting of the document, making them easy to view and share across different devices and operating systems. However, searching for specific information within a PDF file can sometimes be challenging. In this article, we will explore various methods and tools you can use to search for text within a PDF document.
Using Adobe Acrobat Reader
Adobe Acrobat Reader is one of the most popular PDF viewers and offers powerful search functionality. Here’s how you can search for text in a PDF using Adobe Acrobat Reader:

- Press Enter to search for the text within the PDF document.
- Adobe Acrobat Reader will highlight all instances of the text within the document.
Using Built-in Search Functionality
Some PDF viewers, such as web browsers like Google Chrome or Microsoft Edge, have built-in search functionality that allows you to search for text within a PDF document. Here’s how you can use the built-in search functionality:

Using Online PDF Search Tools
If you don’t have access to Adobe Acrobat Reader or a PDF viewer with built-in search functionality, you can use online PDF search tools to search for text within a PDF document. These tools allow you to upload a PDF file and search for specific keywords. Here are some popular online PDF search tools:

Advanced Search Techniques
When searching for text within a PDF document, you may encounter situations where you need to use advanced search techniques to find the information you’re looking for. Here are some tips for performing advanced searches in PDF documents:
- Use Boolean Operators: You can use Boolean operators such as AND, OR, and NOT to refine your search queries.
- Search for Phrases: Enclose phrases in quotation marks to search for exact matches.
- Search by Wildcard: Use asterisks (*) as wildcards to search for variations of a word.
- Search by Proximity: Use the NEAR operator to search for words that are close to each other.
Searching Scanned PDFs
Scanned PDFs, also known as image-based PDFs, pose a challenge when it comes to searching for text since the text is embedded in the image. To search for text in scanned PDFs, you can use optical character recognition (OCR) software. OCR software converts images of text into searchable and editable text. Here are some popular OCR software tools:
- Adobe Acrobat Pro: A comprehensive PDF editor that includes OCR functionality.
- ABBYY FineReader: A powerful OCR software tool for converting scanned documents into searchable text.
- Tesseract OCR: An open-source OCR engine that is widely used for text recognition.
