A scanned PDF is only pictures of pages, so you can't search it or select its text. Open it in the PDF editor of Eofent Capture and choose Make searchable. It reads the pages on your computer and lays an invisible text layer over each word.
7 STEPS · CHROME AND EDGE
Open the PDF tab, press Open a PDF and pick the file.
You will find it with the quick tools on the left, or in All tools. Each page shows whether it is scanned or already has text.

Choose the language the document is written in, so the words are read correctly.
Standard takes a second or two per page. Best is slower and gets more words right.
Scanned only skips pages that already have text. You can also choose All, or a Range.
