# What is a searchable PDF? — DocFind

**A searchable PDF is one whose words are stored in the file as text, so a find command, a copy, or a screen reader has something to work with. A PDF exported from a word processor is searchable from the start. A scanned PDF is a picture of a page until OCR (optical character recognition) reads it and stores the recognised words with the image, which is the step Adobe describes as converting "text images into searchable, selectable text"** ([*Scanned PDF settings*, Acrobat Desktop Help](https://helpx.adobe.com/acrobat/desktop/create-documents/scan-documents-to-pdfs/scanned-pdf-settings.html), read 21 October 2026). Two PDFs can look identical on screen and still differ on exactly this point.

## The three kinds you will meet <ul> <li>**Born digital.** Made by software that already had the words: a document exported to PDF, a bank statement generated by a server. The open-source tool OCRmyPDF calls this "“born digital” content that doesn’t require text recognition" ([*Introduction*, OCRmyPDF documentation](https://ocrmypdf.readthedocs.io/en/latest/introduction.html), read 21 October 2026). It is searchable as soon as it exists.</li> <li>**Image only.** Made by a scanner or a phone camera with no recognition step. Adobe's wording is that such a file "contains only image data, not searchable text" ([*Recognize text in scanned documents*, Acrobat Desktop Help](https://helpx.adobe.com/acrobat/desktop/create-documents/scan-documents-to-pdfs/recognize-text.html), read 21 October 2026). You can read it; your software cannot.</li> <li>**Image plus a hidden text layer.** A scan that has been through OCR. The picture stays exactly as it was and the recognised words sit behind it, which Acrobat describes for doubtful words as "visually showing the original image but placing searchable text behind it" ([*Fix text issues in scanned PDFs*, Acrobat Desktop Help](https://helpx.adobe.com/acrobat/desktop/create-documents/scan-documents-to-pdfs/fix-scanned-text.html), read 21 October 2026). OCRmyPDF's one-line summary of its own job is the same idea: it "adds text “layers” to images in PDFs, making scanned image PDFs searchable" (the OCRmyPDF page above).</li> </ul> <p>One file can mix them. A typed report with a few scanned pages bolted on is searchable for some pages and not others, and nothing on screen marks the boundary.</p>

## What a search actually reaches <p>"Searchable" usually means the body text, but a PDF can hold words in other places too. Adobe lists what its own search covers: "Acrobat searches the PDF body text, layers, form fields, and digital signatures", and "You can also include bookmarks and comments in the search" ([*Searching PDFs*, Adobe Acrobat Help](https://helpx.adobe.com/acrobat/using/searching-pdfs.html), read 21 October 2026). That list is Acrobat's; other viewers may reach less, so a word typed into a form field or left in a comment can be findable in one app and not in another.</p>

## Searchable is not the same as correct <p>OCR guesses at shapes, and the guess is what gets stored. Adobe's tools say so: when "a match is uncertain, it marks the word as a suspect", and its advice after any recognition pass is to "review the document to ensure the text is accurate and complete" (the *Fix text issues* and *Recognize text* pages above). A misread word is the awkward case, because the page looks searchable and still misses the term you type. A clean, straight, well-lit scan gives recognition its best chance.</p>

## Searchable in one app is not a searchable file <p>Some viewers do the recognition for you while the file is open. Google says that in Chrome on a computer, "scanned PDFs of physical documents are automatically converted to be searchable and selectable using Optical Character Recognition (OCR)", on your device ([*Manage PDFs in Chrome* (Computer), Google Chrome Help](https://support.google.com/chrome/answer/16215622?hl=en&co=GENIE.Platform%3DDesktop), read 21 October 2026). The same page does not say that the recognised text is written into the file when you download it, so do not assume a scan that searched well in Chrome will search anywhere else. To find out what a given file holds, [try to select a word](https://docfindapp.com/answers/does-my-pdf-have-a-text-layer); to give a scan a real text layer, [run OCR on it](https://docfindapp.com/answers/make-a-scanned-pdf-searchable).</p>

## Where DocFind fits <p>[DocFind](https://docfindapp.com/) searches both kinds without asking you to convert anything. It reads scanned PDFs on your device, then searches them like any other document, across many PDFs at once, and matches found through OCR are labelled as such, so you can tell a word the file stored from a word the app recognised. It does not write that text back into your PDF, because it never changes the files you search: a scan that searches in DocFind stays image-only for every other app. Its recognition is for printed text, not handwriting; on Android it reads Latin-script print only, and scanned Hindi pages are not read on either platform.</p>
