About the Image to Text (OCR)
Extracts readable text from a photo or scanned document directly in your browser, so you can copy text out of an image without retyping it.
How to use it
- Upload an image containing printed text.
- Click Extract text and wait for recognition to finish.
- Copy the extracted text with the copy button.
Formula
Uses Tesseract, an open-source OCR engine, compiled to WebAssembly (via tesseract.js) so it runs entirely in your browser rather than on a server.
Worked example
A clear photo of a printed paragraph typically extracts with high accuracy; a blurry, low-contrast, or heavily stylized image extracts less reliably.
Recommendations
- • Good lighting and a straight-on angle improve accuracy more than image resolution alone.
- • Crop out irrelevant background before uploading — the Image Cropper works well for this.
- • For dense multi-column documents, expect more line-ordering mistakes than a simple single-column page.
Frequently asked questions
No — recognition runs entirely in your browser using WebAssembly. The OCR engine itself (not your image) is fetched from a public CDN the first time you use the tool, a one-time download of generic software, not your data.
