OCR Software for Mac: What the Built-in Tools Can Do and When an App Is Worth It

When people look for OCR software on a Mac, they usually want one of three things: copy text from an image, make scanned PDFs searchable, or grab text from the screen that can't be selected. For the first, macOS is enough. For the other two, the system hits its limits, and that is where an app is worth it. This article shows what the built-in tools can do, where they stop, and which software fits which job.

What macOS can do without extra software

Since macOS Monterey, text recognition is built into the system. Apple calls it Live Text. It runs locally on your Mac, without uploading anything.

• Photos, Preview, Quick Look and Safari: you can select and copy text in images with the mouse, just like regular text.
• Shortcuts: the action “Extract Text from Image” reads the text from image files. You can use it to process several images in a row.
• Spotlight: text in image files is recognized in the background and then becomes searchable. This takes a while, because macOS analyzes images at low priority.

For everyday tasks, such as a phone number from a photo or a sentence from a screenshot, that's all you need.

The limit: scanned PDFs

A PDF from a scanner is just a series of images at first. It only becomes searchable once text recognition adds an invisible text layer. macOS doesn't do that:

• Live Text recognizes the text while you look at the document, but doesn't save a text layer into the PDF.
• macOS doesn't analyze images inside PDFs for search. A scanned contract without a text layer stays invisible to Spotlight, no matter how well the index is maintained.

This affects exactly the documents you need to find again later: invoices, contracts, official letters. Why search fails here is explained in Spotlight Not Finding Files.

OCR software for Mac: which one for which job

Adding a text layer: PDF apps and OCRmyPDF

If you want scans to be searchable for good, you write a text layer into the PDF. After that, Spotlight finds the content too. Large PDF apps such as Adobe Acrobat Pro (subscription) and ABBYY FineReader PDF can do this, also for several files at once.

Free and thorough is OCRmyPDF, an open-source tool for the Terminal. With Homebrew it is set up in two lines:

brew install ocrmypdf
ocrmypdf scan.pdf scan-searchable.pdf

For other languages, install tesseract-lang as well and pass the language, for example -l deu for German.

The downside of all three: every file has to go through text recognition once, and every new file again. With an archive of thousands of pages, that's a lot of manual work unless you automate it.

Searching scans without changing them: PDF Content Search

The second approach leaves your files as they are and builds its own search index. That's how PDF Content Search works, which I develop myself. You choose a folder, the app recognizes the text with Apple's text recognition and makes everything searchable: amounts, IBANs, names, contract numbers.

• scanned PDFs, images and text files, plus Apple Mail with PDF and image attachments
• its own index, independent of Spotlight; watched folders stay up to date automatically
• matches are highlighted in the document
• AI assistants such as Claude Desktop, Claude Code, VS Code or Cursor can search your documents via MCP, connected locally and only when you switch it on
• text recognition, index and search run locally on your Mac, no cloud for your files

To be honest: the first text recognition of a large archive takes computing time here too. After that, the app only works when new documents arrive. What this looks like in practice is shown in Finding Scanned Letters on Your Mac.

Text from the screen: FreezeText

Some text you can see but can't select: in a video, in a popup that disappears after three seconds, or in a PDF with copy restrictions. With built-in tools, the only way is a screenshot detour. FreezeText freezes the whole screen with a keystroke. You draw a rectangle around the text, and the result is on your clipboard. Recognition runs through Apple's Vision framework on your Mac, nothing is uploaded. FreezeText costs €19.99. A similar app is TextSniper. Details are in Copy Text From Videos, Popups and Protected PDFs.

What to look for in OCR software

• Local or cloud: online OCR services require you to upload documents. For contracts, invoices and official letters, local processing is the safer choice.
• Text layer or own index: a text layer changes the file and helps every app. An own index leaves the file unchanged and picks up new files automatically.
• Languages: set the recognition language to match your documents, otherwise accents and special characters suffer.
• Volume: for a single document almost anything works. With hundreds of files, batch processing and watched folders matter.

Frequently asked questions

Does the Mac have built-in OCR?
Yes. Since macOS Monterey, Live Text recognizes text in images, in Photos, Preview, Quick Look and Safari. macOS does not write a text layer into PDFs, though.

Can Preview make scanned PDFs searchable?
No. Preview recognizes text while you view it, but doesn't save it into the PDF. For that you need a PDF app with OCR, OCRmyPDF or a search tool with its own text recognition.

Which OCR software for Mac is free?
Live Text and the Shortcuts action “Extract Text from Image” are part of macOS. For searchable PDFs, OCRmyPDF is free but requires the Terminal.

Why doesn't Spotlight find my scanned documents?
Because they have no text layer. Spotlight doesn't analyze images inside PDFs. The fix is a text layer or a search tool with its own text recognition.
