🔎 PDF OCR
🔒 Client-Side OnlyWhat Is PDF OCR?
OCR stands for optical character recognition, a technology that analyzes an image of text and converts it into machine-readable, selectable text. When a PDF is made from a scanned document or a photo, the "text" on the page is really just a picture; you can't select, search, or copy it the normal way. OCR solves that by reading the shapes of the letters and turning them back into actual text characters.
This tool renders each page of your PDF as an image and then runs OCR on it directly in your browser, producing plain text you can copy or download.
How to Extract Text from a Scanned PDF Step by Step
Pulling text out of a scanned PDF takes just a few steps:
Upload Your PDF
Drag and drop your scanned or image-based PDF into the upload area.
Pick a Language
Choose the language that matches the text in your document for best accuracy.
Click Extract Text
The tool runs OCR page by page, right in your browser.
Copy or Download
Copy the extracted text or download it as a .txt file.
Why Use NexaTools PDF OCR
Many online OCR tools require uploading sensitive scanned documents to a remote server, or they cap how many pages you can process for free. NexaTools takes a different approach: the entire OCR process happens locally in your browser using JavaScript, so your document is processed on your own device and is never transmitted anywhere.
100% Private. Your PDF never leaves your device. There is no server upload involved.
Multiple languages. Choose from several supported OCR languages.
Completely free. No credit card, no hidden fees, no premium tier, unlimited use.
Works everywhere. Fully responsive on desktop, tablet, and mobile browsers.
Who Should Use This Tool
NexaTools PDF OCR is built for anyone who has a scanned document and needs the text inside it, without installing software or uploading files to a third-party server.
Students & researchers pulling quotes and passages out of scanned textbooks or papers.
Office staff digitizing old scanned contracts, forms, and letters.
Archivists converting scanned records into searchable text.
Freelancers extracting text from client-provided scanned documents.
Common Use Cases
People use PDF OCR for many different everyday reasons. Some of the most common include:
Digitizing paperwork. Turn scanned forms and contracts into editable text.
Making documents searchable. Extract text so you can search and find information faster.
Copying quotes. Grab a passage from a scanned book or article without retyping it.
Archiving records. Convert old scanned files into plain text for storage or backup.
How Your Privacy Is Protected
When you upload a file into the tool above, it is read directly by your browser's own file-reading APIs, rendered onto a canvas, and analyzed using OCR that runs with JavaScript on your device. At no point is the file sent across the internet to a remote server or stored in any database. Once you close or refresh the tab, the file and the extracted text are simply gone from memory. This local-first design means there's nothing for anyone including NexaTools to access, log, or retain.
Common Problems & Troubleshooting
"Extract Text" stays disabled. This button only activates after a valid PDF has been uploaded.
Extraction is slow. OCR is processor-intensive; large PDFs with many pages take longer since everything runs locally in your browser.
Extracted text has errors. Try selecting the correct language, or use a higher-quality scan for better accuracy.
"This file could not be read." The PDF may be corrupted or password protected. Remove any password and try again.
