# Is your PDF actually searchable?

*Last reviewed: September 2, 2026 · [HTML version](https://docfindapp.com/tools/is-your-pdf-searchable)*

Some PDFs are text. Some are *photographs* of text. They look identical on screen, and only one of them
can be searched — which is why "search inside this PDF" sometimes finds nothing in a document you can
plainly read with your own eyes.

The tool on the HTML version of this page checks a PDF you choose and tells you which kind you have.
**The file never leaves your browser**: nothing is uploaded, no network request carries it anywhere, and
nothing is stored.

## What the answer means

**"Has a text layer"** — the words are really in the file as text. Most PDF readers can find them,
though not every mobile viewer offers a search box. If searching still fails, the problem is the search, not the document.

**"No text found — this looks like a scan"** — the file has page images and no text-drawing instructions. Nothing in the file says "this pixel is the
letter A", so there is nothing for a search to match. To make it searchable, the picture has to be run
through OCR (optical character recognition), which looks at the shapes and writes a text layer underneath.

**"Contains both text and images"** — the file has a text layer and it also has images. *Which pages are
which is not something this check can tell you* — it reads the file as a whole, not page by page.

**"Can't say for this file"** — parts of the PDF use a compression this page cannot read, so a "no text
found" answer would not be trustworthy. The file may well be searchable.

**"Encrypted — it may still be searchable"** — PDF encryption comes in two kinds. A **user password** is
asked for before the file opens, and until it is removed nothing inside can be read by anything. An
**owner password** (restrictions on printing or copying) opens without prompting, and DocFind indexes and
searches it like any other document. This page reports that a file is encrypted but does not try to tell
the two apart — the quickest test is to open it in any reader and see whether you are asked for a password.

## The honest limits — ours and OCR's in general

- **Handwriting is not recognised.** DocFind's recognisers are built for printed text. A handwritten page
  will not become searchable, here or in the app.
- **On Android, a *scanned* page in a non-Latin script — Hindi, Chinese, Arabic — will not become
  searchable**, because the recognizer bundled with the app covers Latin script. A PDF that already has a
  non-Latin *text layer* searches normally on both platforms. The distinction is between a picture of the
  words and the words themselves.
- **Search matches what you type.** DocFind looks for the word you asked for and does not guess at
  related words, so "running" will not find "run". That is deliberate — you can trust a hit.
- **PDFs only.** Word, Excel and plain-text files are not supported.

## About the app

DocFind searches inside many PDFs at once, and reads scanned pages by running OCR on your
device. Nothing is uploaded: the index is built and stays on the phone, and the iPhone app ships with no
network capability at all. iPhone and Android.
