Copy Text from a Non-Selectable PDF on Mac
By Eduard Bruch, developer of Optic · Updated
A PDF that will not let you select text is usually a scan: each page is an image of text, not text itself. To copy from it on a Mac, try selecting the text in Preview (Live Text may recognize it), or use a screen OCR app to read the part of the page you need off the screen.
Short answer: Preview with Live Text is worth one try. When it does not pick the text up, my pick is Optic, a menu bar app that copies the text in any area you drag across the screen ($4.99, a one-time purchase on the Mac App Store).
Disclosure: I build Optic.
Why some PDFs have no selectable text
A PDF can hold real text, images, or both. Scanned documents, photographed pages, faxes and some exported forms contain only images of the pages. Every PDF viewer sees the same thing: pixels shaped like letters, with no characters underneath to select.
A second, rarer case is a PDF whose author has restricted copying. That is a choice by the document's owner. Make sure you have the right to reuse the text before you copy it by any route.
Try Preview first
Live Text works where Apple supports it: images in Preview, Photos, Quick Look and Safari. It does not work on arbitrary app windows, video calls or UI text.
- Open the PDF in Preview.
- Zoom in so the text is large and sharp.
- Hover over a line. If the cursor becomes a text cursor, drag to select and press Command-C.
Whether this works depends on the document. If nothing highlights, move on to the next option.
Copy the text from the screen with Optic
Optic does not care how the PDF was made. It reads what is visible on screen inside a box you draw.
- Open the PDF in Preview or any PDF viewer and zoom to a comfortable size.
- Click the Optic icon in the menu bar.
- Choose Capture Text and drag a box over the paragraph you need.
- Paste with Command-V.
Recognition runs on your Mac with Apple's Vision framework at its accurate setting, so the document never leaves your computer. Larger, sharper text on screen gives better results, so zooming in before you capture helps with small print and faint scans.
Cleaner paragraphs
Scanned pages often break lines in the middle of sentences. In Settings, set line breaks to Smart merge to join wrapped lines while keeping sentence ends, or Remove to get one long line. Trim whitespace is on by default.
Working through several pages
Optic captures one area at a time. For a few paragraphs across several pages, scroll, capture, paste, and repeat. The menu bar history keeps your last 20 captures if you want to paste them later in a different order.
Mixed languages
Scans in other languages work as long as the language is one of the 21 Optic recognizes, such as German, French, Spanish, Polish or Japanese. Each language can be switched on or off in Settings.
Extract text from a whole PDF on Mac
If you need all the text of a PDF rather than a passage, the route depends on the file. A PDF with a text layer: open it in Preview, press Command-A, then Command-C, and paste. A scanned PDF without a text layer needs a document OCR app that opens files and creates a searchable PDF, such as OwlOCR (its listing states "Export searchable PDFs", checked 2026-10-10). Optic is the other job: it copies the passage you can see, page by page, and does not process the whole file.
Where Optic does not fit
Be clear about the job before you buy anything:
- It does not open the PDF file. The page must be visible on screen.
- It does not OCR a whole document. There is no whole-document mode, no folder processing and no searchable-PDF output. If you need a full scanned book turned into a searchable file, use dedicated PDF OCR software.
- No table extraction. Tables come out as lines of text.
- Handwriting is not a promised feature. It is meant for printed text.
- No translation.
Optic suits the common case: you need a sentence, a paragraph, an account number or a reference from a scan, right now.

For scans in other languages, see OCR foreign language text on Mac; to listen to a captured passage, see read text aloud from the screen on Mac.
FAQ
Why can't I highlight text in a PDF on Mac?
The PDF most likely contains scanned images of pages rather than text. Try Live Text in Preview or a screen OCR tool.
How do I copy text from a scanned PDF on Mac?
Open it in Preview and try selecting the text. If that fails, drag a box over the text with a screen OCR app like Optic and paste.
How do I extract text from a PDF on Mac?
If the text selects in Preview, press Command-A and Command-C. If it is a scan, copy the passages you need with a screen OCR app (my pick is Optic), or use a document OCR app for the whole file. More: best screen OCR apps for Mac.
Can Optic make my PDF searchable?
No. Optic copies text from the area you select to the clipboard. It does not change or create PDF files.
Does the PDF get uploaded anywhere?
Not with Optic. Recognition happens on your Mac and the app has no network access.
