Frequently asked questions

Is my file uploaded to recognize the text?

No. Recognition runs in your browser with tesseract.js, the Tesseract OCR engine compiled to WebAssembly. The only downloads are the program itself and a language model, never your document.

Which languages can it recognize?

English, Spanish, Portuguese, French, German, Indonesian, Simplified Chinese, Japanese and Arabic. Choose the document's language before processing; for Chinese, Japanese and Arabic, English is recognized too, so mixed words come out right.

Can I edit the text after OCR?

The PDF keeps its original appearance, with the recognized text as an invisible layer you can select, search and copy. To edit the text, run the result through PDF to Word, which extracts that layer into a .docx file.

Why are some words wrong?

OCR accuracy depends on the scan. Blurry, tilted or low-resolution pages, handwriting and decorative fonts produce more mistakes. For best results, scan at 300 dpi, keep the page straight and use good contrast.

How it works

From file to finished PDF in three steps

1

Pick a tool

Open any of the 17 tools above and drop in your file — no account, no install, and no upload screen to wait on.

2

Processed on your device

Your browser does the actual work using WebAssembly and JavaScript (pdf-lib, pdf.js), the same technology behind offline apps. The file itself never leaves your computer.

3

Download the result

As soon as processing finishes, your browser triggers a normal file download. Nothing is stored on our end — there's no server copy to delete because one was never made.
