OOCR
What OOCR is
OOCR is a free web OCR tool that turns images into editable text in the browser. You can paste, drop, select, or photograph an image, then copy the recognized text, download a .txt file, or create a searchable PDF with an invisible text layer. It uses PaddlePaddle PP-OCRv6 and offers Tiny, Small, and Medium model variants. Detection and recognition are available for 50 languages, and handwriting OCR is supported. The interface places bounding boxes around recognized regions and keeps them synchronized line by line with the text display. OOCR is an installable progressive web app that caches its model, allowing offline use after the first load. The maker says image and text processing stays in the browser and is not sent to a server. Models use browser storage, OCR content is not kept in cookies, and analytics are off by default. Batch processing handles up to 25 page images. The app is free without login, watermark, page limit, or subscription. JavaScript is required.
