How do I search inside PDFs on a Mac?

Last reviewed: October 10, 2026 · Markdown version

For the PDF you have open, use Preview: type the word into the search field in Preview's toolbar, and every match is listed. For a whole folder of PDFs the built-in tools are Spotlight and the Finder's search, and here Apple's own guides are careful: they talk about finding files, narrowing by kind or name, and an index of "content", without saying in so many words that they match the text inside a PDF. So for many PDFs, a quick test tells you more than the documentation does.

One PDF: the search field in Preview

Apple's steps for Preview on a Mac: "In the Preview toolbar, type a word or phrase in the search field (you may need to resize the window to see it)." Two behaviours are worth knowing. "If you type a phrase, Preview searches for that exact phrase", and to match any of its words instead you open the field's menu and "choose Any Match". The results can be ordered two ways: "Click Search Rank" to sort "by number of matches", or "Click Page Order" to sort by page (Find text in PDFs in Preview on Mac, Preview User Guide, read 10 October 2026). Search Rank is the useful one in a long report, because the pages that mention your word most often come first. The keyboard shortcut, and what a browser's find bar does with a PDF, are on searching for a word in a PDF.

Many PDFs: what Apple says Spotlight does

Apple's Spotlight guide describes it as the way "to find anything on your Mac — your apps, files, emails, messages and more", opened with Command-Space bar. A result can be checked without opening it: "press Space bar on any result — works for documents, images, PDFs and videos" (Find what you need with Spotlight on Mac, Mac User Guide, Apple Support, read 10 October 2026). To keep the list to PDFs, Apple's narrowing page gives a short form: "to narrow search results to PDFs, enter “/PDF”, then press Return". It also lists keywords such as name and contains, to be entered "followed by a colon", without saying what contains looks in (Narrow your search results in Spotlight on Mac, Mac User Guide, Apple Support, read 10 October 2026).

Apple's indexing article comes closest. It says Spotlight's index covers "a wide range of content such as documents, email, text messages, contacts, photos" and more, and that "Spotlight indexes your device so that you can search its contents" (About Spotlight indexing and search results on Apple devices, Apple Support, read 10 October 2026). None of the three pages states that a word printed inside a PDF will bring that PDF up, and none describes showing you the page the word is on.

Many PDFs: the Finder's search criteria

The Finder's search window lets you stack criteria. Apple's examples are Kind, to search "for only a certain type of item", and Name, "to search for any item whose name contains a particular word or phrase" (Narrow your search results in Finder on Mac, Mac User Guide, Apple Support, read 10 October 2026). That page does not describe a criterion for the text inside a file. Its other tips, the kind: keyword and saving a search as a Smart Folder, are covered on searching many files in a folder.

A test worth one minute

Our suggestion, not Apple's: open a PDF you know well, pick a word that is in its text but not in its file name (a supplier's name, a reference number), and search for it in Spotlight with the PDF filter on. If the file comes up, Spotlight is reading that kind of PDF on your Mac. If it does not, the file may be a scan with no text in it; checking for a text layer settles that.

If Spotlight misses files it should find, Apple's indexing article says to check Spotlight in System Settings "to find out whether that type of content is turned on for Spotlight searches", and describes a rebuild: add the disk or folder to the list of places Spotlight is prevented from searching, then remove it, after which "Spotlight now reindexes the contents of the disk or folder" (the About Spotlight indexing article above). On a Windows PC the same problem has a different set of fixes, covered in why File Explorer search is slow.

On your phone instead

DocFind is not a Mac app; it runs on iPhone and Android. If the PDFs you need to search live on your phone, searching inside many PDFs at once explains how it works there, results with the file, the page and the surrounding text included.
