How to Extract Text from Images for Free (OCR Guide)
Learn how to use free OCR tools to extract text from images, screenshots, PDFs, and scanned documents. No upload required — works in your browser.
Need to copy text from a screenshot, a scanned document, or a photo of printed text? OCR (Optical Character Recognition) technology can read text from images and convert it into editable, searchable text. What used to require expensive software now works for free in your browser.
What Is OCR and How Does It Work?
OCR analyzes an image to identify letter shapes and patterns, then converts them into machine-readable text. Modern OCR engines use neural networks to achieve over 99% accuracy on clean text. They can handle various fonts, sizes, and even slightly tilted or distorted text.
Common Use Cases for OCR
Students extracting text from textbook photos for notes. Professionals digitizing scanned contracts or receipts. Writers pulling quotes from screenshots. Developers extracting data from UI mockups. Anyone who needs to convert a non-editable image into text they can copy, search, and edit.
Privacy Matters for OCR
Most online OCR tools upload your image to a server for processing. This is a privacy risk, especially with sensitive documents like contracts, medical records, or financial statements. Browser-based OCR processes everything locally — your images never leave your device.
