Can I extract text from an image using OCR in the browser?
Yes. Browser OCR uses libraries like Tesseract.js to read text from screenshots, scans, and photos without uploading them. Clear, high-contrast images with horizontal text work best; skewed or blurry shots lower accuracy. Crop to the text region first, pick the document language, run recognition, then copy or export plain text. OCR in the browser suits quick notes from whiteboards, receipts, or book pages when privacy matters more than enterprise accuracy. It is weaker than dedicated server OCR on multipage PDFs — for born-digital PDFs, use PDF-to-text instead. Processing large images can take tens of seconds on older phones because OCR is CPU-heavy. EasyPDFHub’s image-to-text tool is free and keeps files on your device.
