You open a PDF, try to select a sentence to copy — and nothing highlights. That's because it's a scanned PDF: each "page" is actually a picture of a document, not real text. To get the words out, you need OCR. Here's how to do it for free, without any software.
Why you can't select text in a scanned PDF
There are two kinds of PDFs. A digital PDF (exported from Word, a browser, and so on) contains real, selectable text. A scanned PDF is built from photos or scans of paper — so as far as your computer is concerned, every page is just an image. That's why the highlight tool does nothing. OCR is what turns those page-images back into text.
The method: PDF to images to text
The reliable free approach has two simple stages: first turn the PDF's pages into images, then run OCR on each image. No installs, no accounts.
Step by step (free)
- Convert your scanned PDF's pages to images with PDF to JPG — each page becomes a JPG.
- Open the Image to Text tool and drop in a page image.
- Copy or download the extracted text. Repeat for each page.
Handling multi-page PDFs
For a long scanned document, convert all the pages to images in one go with PDF to JPG, then run each page through the text extractor and paste the results together in a document. If you later need to bundle images back into a single PDF, Image to PDF does that too.
Getting accurate results
Scanned documents vary in quality, so a few pointers:
- Higher-resolution scans read better. If you're scanning the paper yourself, use 300 DPI or more.
- Straight pages matter. A skewed scan trips up OCR — straighten it if you can.
- Pick the right language in the tool so accented characters come through correctly.
- Edit afterward. The extracted text is editable, so fix any stray characters before saving.

Frequently asked questions
It's a scanned PDF, meaning each page is an image rather than real text. You need OCR to convert the page-images into selectable text.
Convert the PDF pages to images with a PDF to JPG tool, then run each image through an OCR tool like Image to Text and copy the results. Both steps are free and run in your browser.
Yes. Doing it with Pixveil's browser tools keeps everything on your device — nothing is uploaded — which is important for the contracts and statements that scanned PDFs usually contain.
Convert all pages to images at once, run each through the text extractor, and combine the text. It's a page-by-page process, but quick once you have the images.
