PDF OCR Tool
AIfreeforever's PDF OCR tool converts scanned documents into editable, searchable text right inside your browser. Upload any image-based PDF, select your language, and let the optical character recognition engine analyze every page. Four specialized modes handle different scenarios: Full Page OCR for complete document extraction, Region OCR for targeted text capture, Batch OCR for processing multiple files, and Handwriting OCR for notes and forms written by hand. Your files stay on your device because all processing happens locally with no server uploads.
Full Page OCR
Scan every page of your PDF and extract all visible text with a single click using optical character recognition.
Region OCR
Draw a selection rectangle on the PDF page to extract text from a specific area like a table, header, or paragraph.
Batch OCR
Add multiple PDF files and run optical character recognition on all of them in a single batch operation.
Handwriting OCR
Extract handwritten text from scanned notes, forms, and letters with optimized recognition settings.
How PDF OCR Extracts Text from Scanned Documents
Because scanned PDFs are just images saved as a PDF, you usually cannot select, search, or copy the text inside them. Our tool fixes this by turning each page into a high-resolution image and processing it with the Tesseract.js engine right in your browser tab. It recognizes characters, words, and lines to reconstruct your text while keeping the original formatting intact. You will even see a confidence score for each run, making it easy to spot any areas that might need a quick manual check.
Multi-Language Support for Global Documents
You can pick from 12 supported languages, including English, Spanish, French, German, Chinese, Japanese, Korean, Arabic, Hindi, and Russian. By selecting the right language, you load a specific model tailored to that script, which gives you much better accuracy than a one-size-fits-all approach. If you need to switch languages, the change happens instantly for your next run without needing to refresh the page.
Region Selection for Targeted Extraction
If you only need a specific snippet of text, Region OCR lets you skip the rest of the page and focus on exactly what you want. Just click and drag on the preview to highlight the target area with a blue rectangle. This speeds things up significantly because the engine only looks at those specific pixels, automatically ignoring headers, footers, or any notes in the margins.
Online PDF OCR with Batch Processing
While one-by-one processing is fine for quick jobs, digitizing a whole folder of files is much easier with our batch mode. You can queue up multiple PDFs and let the tool process them all in order. You can track the progress and see confidence scores for each file right in the sidebar. Once finished, all the text is neatly organized in the output panel with file headers, so you can copy or download everything as one convenient text file.
Handwriting Recognition for Notes and Forms
Handwriting OCR applies the Tesseract engine to documents containing handwritten content such as notes, medical forms, legal documents, and personal letters. Recognition accuracy depends on handwriting legibility, pen contrast, and scan resolution. For best results, scan your handwritten documents at 300 DPI or higher with good lighting and a clean white background.
Copy or Download Extracted Text
As soon as the OCR process wraps up, your text appears in the side panel along with a character count. You can copy everything to your clipboard with a single click or save it as a text file named after your document. The tool keeps the text in the correct reading order, so it is ready for you to paste into a Word doc, spreadsheet, or any other app.
Free PDF OCR with Complete Privacy
Scanned files often hold sensitive details that you should not have to upload to a random server. That's why this tool handles everything right in your browser tab using a client-side engine. Your document renders locally, the text recognition runs locally, and your output is saved locally. Since nothing ever crosses the network or gets stored on our end, your privacy is completely protected without even needing an account.
No Account, No Upload, No Storage
All four PDF OCR modes are available the moment you open the page with no sign-up, no email, and no payment. Your files live only in browser memory while the tab is open and vanish completely when you close it. There are no usage limits, no premium tiers, and no watermarks on the output text.
Client-Side Processing for Document Security
Since the entire process runs through JavaScript and WebAssembly in your browser, your documents never actually travel across the internet. You can process medical records, tax forms, or legal contracts with the peace of mind that your confidential information stays strictly on your own computer.
