Extract Text from a Scanned PDF (OCR)

A scanned PDF looks like text, but to a computer it's just a picture. You can't select it, search it, or copy a single word. OCR (Optical Character Recognition) fixes that by reading the shapes of the letters and turning them back into real, editable text. This guide shows you how to do it in a few clicks.

What is OCR, and when do you need it?

OCR is the technology that recognizes printed or handwritten characters inside an image and outputs them as machine-readable text. You need it whenever a PDF was created by scanning paper or from a photo, rather than exported from a word processor. A quick test: try to select a line of text with your cursor. If nothing highlights, the page is an image and OCR is the tool for the job.

Extract text in 4 steps

1. Open the OCR tool and upload your scanned PDF.
2. Choose the language of the document for the most accurate results.
3. Start the scan and let it process each page.
4. Copy the recognized text, or download it for editing.

The recognition runs locally on your device. There is no upload, no account, and no watermark on the result.

Tips for the best OCR accuracy

• Use a high-resolution scan. 300 DPI or higher gives the engine crisp letter shapes to work with.
• Keep pages straight. Skewed or rotated scans hurt accuracy — straighten them before running OCR.
• Pick the right language. Selecting the document's language dramatically improves recognition of accents and special characters.
• Prefer clean contrast. Dark text on a white background reads far better than faint or shadowed scans.

Common uses

• Copying quotes or figures out of a scanned report.
• Making an old contract searchable so you can find a clause fast.
• Digitizing receipts, notes, or book pages into editable text.
• Pulling data from a scanned form into a spreadsheet.
