How it works

Complete the job in three clear steps

Add a clear image containing printed text to the private browser workspace.
Choose the available settings and create editable recognized text and confidence details.
Review the result, then copy or download it before leaving the page.

Important

Check the result before relying on it

Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.

Practical details

What this Lucaden tool does

The OCR engine runs in a web worker after downloading the selected language data. Source images are not uploaded to Lucaden, but the initial language model download can be large. Clear, upright, high-contrast text produces the best result.

Lucaden performs this task in the browser so the source stays under your control. The result is created only after you request it, and nothing is saved to a Lucaden account by this tool.

Browser-worker OCR

Questions

About this tool

Why does OCR take time on first use?

The browser must download and initialize the recognition engine and language data before processing locally.

Is OCR output always accurate?

No. Fonts, blur, skew, lighting, handwriting, and page layout affect accuracy. Always compare important text with the source image.
