  4. Click on the previous and next buttons to move through the results that match your search word or phrase in the document.

How to check if your PDF is searchable.

For a PDF to be searchable it must be text-based. That means individual characters or letters are recognized. To find out whether your current PDF is searchable, can you follow these steps:

  1. Open the PDF you want to search on your phone or computer using an Acrobat app.
  2. Press the Ctrl+A keys to “Select All.” If your PDF is text-based this will select and highlight the text in the file, as shown below.

  1. If nothing is selected, there is no text, and the file isn’t searchable as it is.
  2. You can also simply try selecting text with your mouse or keyboard after opening the PDF. If you can’t select or highlight text, then the PDF is not currently text-based.

Why your PDF might not be searchable – and the solutions.

In terms of formatting, PDFs can be powerful documents that you can do a lot with. PDFs can be searched, edited, interactive, shared, signed, encrypted and more.

This can happen if the document has been scanned as a flat image to PDF format. What this means is there are no text characters that your PDF viewer recognizes. Fortunately, it’s easy to resolve this issue. Use the optical character recognition (OCR) technology in Acrobat to make your PDFs searchable and editable.
