OOCR review
A free local OCR tool for private screenshot, document, and handwriting extraction.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OOCR is a free, browser-based OCR tool for extracting text from screenshots, scans, photos, receipts, documents, and handwriting. It runs PP-OCRv6 through WebAssembly in the browser, keeping images and recognized text on the device rather than sending them through an image upload path. The tool is suited to people who want private OCR without an account, server processing, watermarks, or page limits, especially when their main workflow starts with screenshots or other image files.
Its strongest fit is local processing combined with a practical browser workflow. Users can paste, drop, or select images, copy recognized text, download plain text, and create searchable PDFs with an invisible text layer. Live bounding-box overlays stay synchronized with recognized text, which can help with reviewing recognition results. Screenshot-to-text through clipboard paste is particularly relevant for quick extraction, while selectable Tiny, Small, and Medium handwriting models give users control over the handwriting workflow. After the model is cached, the progressive web app supports offline use.
OOCR keeps its scope narrow. The input is image-based, and its output options center on plain text, .txt downloads, clipboard copying, and searchable PDF creation rather than a broad integration or export ecosystem. Its web platform also means the browser is the main operating environment, with offline access tied to model caching. Choose OOCR if private, local OCR and simple screenshot-to-text work matter more than integrations or varied input formats. Consider another OCR product if you need broader platform coverage, non-image inputs, or deeper connections to other software.
