What Is a Searchable PDF? Why My PDF Is Not Searchable?

A searchable PDF is the PDF file composed of 2 layers, image layer and text layer. There in the text layer saves the text content and users are allowed to search for or locate the keyword within the document. 

If your PDF is not searchable, it is much likely that the file is not originally generated from documents editors like Adobe, Microsoft Office, it is image-based, which means the text layer is filled with bitmap fonts. These fonts cannot be recognized, therefore the PDF tool cannot do the matching to locate the keywords.
