How to Make a PDF Searchable

Many PDF files these days are not searchable, making it hard to find specific text in a document. Fortunately, several online tools let you make a PDF searchable with OCR (Optical Character Recognition) technology and text recognition.

These tools are free with limited features but are more affordable than costly PDF software you may only use once or twice. You can simply upload your file, press a button or two, and download the searchable document.

Is My PDF Searchable?

One of the easiest ways to see if your PDF is searchable is to look for particular text that you know exists in the document. Depending on the PDF tool or platform you’re using, you may have a few ways to search for text.

Here are some examples:

• Adobe Acrobat Reader on Windows or Mac: Select Edit > Find from the menu.
• PDFelement on Windows: Select the Search icon on the left.
• Preview on Mac: Select Edit > Find from the menu bar and choose Find.
• Keyboard shortcuts: On Windows, press Ctrl + F, or on Mac, press Command + F.

When the search box opens, type your text and press Enter, Return, or the search button. If you see a message that the text could not be found, and you know it should be, your PDF document is not searchable.

Once you confirm that you’re unable to search the document, check out one of these online file converters. You can quickly and easily make searchable PDF files using OCR technology.
