How to Make a PDF Searchable - Easy Guides & Tips

You can usually use the Ctrl+F shortcut or a direct search option in your PDF reader to search for specific names, numbers, or other keywords in a document. This saves significant time in acquiring key information, compared with reading through the entire document manually. However, a PDF may be non-searchable at times, depending on how it was created or for other reasons. When you enter a word, it shows no results, though you have already seen a matching instance on the current pages.

An additional step is required to work with these non-searchable PDFs normally. And this post shows you how to make a PDF searchable. Check out the details.

What Is a Searchable PDF? Searchable Vs. Non-Searchable PDF

A searchable PDF is typically created from a text file and contains a real text layer. You can use the Search & Find feature to quickly locate and highlight specific words or phrases. With the appropriate permissions, you can also copy and edit the text. 

When a PDF is created from physical paper scans, screenshots, or images, the text content may look normal but it is actually embedded in the image layer rather than stored as actual characters. Without extra processing, it is impossible to search, select, and edit the file.

How to Check Whether Your PDF is Searchable?

There are various ways to verify practicability. Try this method on a Windows PC:

Step 1. Open the PDF file with your regular PDF reader.

Step 2. Move your cursor to any word or line and click on it. Alternatively, you can type a word displayed in the PDF into the built-in Search & Find textbox. 

Step 3. If the PDF is searchable, the target word or phrase will be highlighted. Otherwise, the whole page will be selected.

How to Make a PDF Searchable with OCR?

How do I make a searchable PDF document? A common method is to apply text recognition to the PDF. Most PDF software and online services use OCR (Optical Character Recognition) technology to convert image-based content into machine-readable text, making it searchable, selectable, and editable. Continue reading to learn about some of the best PDF OCR tools and how to use them to make a PDF document text searchable.
