4 Methods to Make PDF Searchable Hurriedly

It is becoming increasingly common for PDF files to lack search functionality, making it difficult to locate specific content inside a document. The good news is that you can use OCR (Optical Character Recognition) and text recognition using numerous programs to make PDF searchable.

Instead of investing in pricey PDF software that you might only use once or twice, you can get by with these tools for free despite their restricted functionality. Just upload your file, click a few buttons, and you'll have a searchable document downloaded to your computer.

Part 1. What is a Searchable PDF?

The process of applying OCR, or optical character recognition, to scanned PDFs or other image-based documents typically results in the creation of searchable PDFs.

During the process of text recognition, both the characters in the document and the structure of the document itself are examined and "read." The picture layer receives a text layer, which is often positioned beneath the image.

These PDF files are completely searchable and practically impossible to tell apart from the original papers they were created from. Documents in PDF format that support searching can have their text highlighted, copied, and annotated.

Part 2. Why are some PDFs not Searchable?

When a PDF was created from an image rather than from a written document, the resulting PDF file does not include any text that can be searched by default. In order to utilize Adobe Acrobat to convert a PDF, the original picture must have a resolution of 72 dpi or higher.

The content of a document does not become searchable instantly once it is either converted to a PDF document or produced as a PDF document. A PDF's text may be made searchable even if it was scanned and stored as an image by using the program's OCR text-recognizing feature and saving the file.

Another reason that can make your PDF unsearchable is the use of a password on your PDF document. In simple words, if your PDF file is password protected, you cannot search the text in it. You will have to enter the password to make it searchable.

Part 3. How to Find Out if Your PDF is Searchable or Not?

Simply opening your PDF and exploring by searching for or selecting text using your keyboard or mouse will help you determine whether or not your PDF is searchable.

If you are able to choose or highlight text in your PDF file, this indicates that it is searchable. If you are unable to, this indicates that the PDF you are using is not searchable.

Either way, you will have to open your PDF file. You cannot determine if your PDF is searchable or not without opening it.
