PDF OCR — Make a Scan Searchable

Read the text off scanned pages, in twelve Indian languages and several others, with pages rendered at print resolution first for accuracy.

Nothing is uploaded — the text is read on your device.

Your file never leaves this device. The whole operation runs in your browser — nothing is uploaded, queued on a server, or deleted later, because nothing was ever sent.

Rendered at 300 DPI before reading

OCR accuracy is dominated by input resolution, and running it on a screen-resolution render is the usual reason people conclude OCR does not work. Pages are rendered at print resolution first, which costs a little time and makes the difference between usable text and noise.

Twelve Indian languages, and the model comes to you

Hindi, Bengali, Tamil, Telugu, Marathi, Gujarati, Kannada, Malayalam, Punjabi and Urdu, plus English and several others. The recognition model downloads once, around 15 MB, and is then cached. That download is the only network traffic — your document still never leaves the device.
Why use it

Built to be genuinely useful

Rendered at 300 DPI first

OCR accuracy is dominated by input resolution — this is why other browser OCR tools disappoint.

Indian languages

Hindi, Bengali, Tamil, Telugu, Marathi, Gujarati, Kannada, Malayalam, Punjabi and Urdu.

Confidence reported

You are told how sure the recognition was, rather than handed text of unknown quality.

Your file never leaves the device

The conversion happens in your browser. Nothing is uploaded, so nothing has to be trusted or deleted later.

How it works

Three steps

  1. 1

    Drop in the scanned PDF.

  2. 2

    Choose the language of the document — this matters a great deal.

  3. 3

    Read a few pages at a time, then copy or download the text.

Why resolution decides the result

Optical character recognition works by matching shapes. At screen resolution — 96 DPI or below — the strokes that distinguish a 5 from an S, or a त from a न, are only a pixel or two wide, and the match becomes a guess.

Pages here are rendered at 300 DPI before recognition. It costs a few seconds a page and it is the difference between usable text and noise. Tools that skip it are the reason people conclude browser OCR does not work.

Language selection is not optional

Each language has its own trained model. Running an English model over Devanagari produces confident nonsense rather than an error, because the recogniser will always find *some* Latin letter that resembles each shape.

If the output looks like gibberish, check the language before anything else.

What is downloaded, and what is not uploaded

The recognition model — roughly 15 MB for a language — is fetched once and then cached by your browser. That download is the only network traffic involved.

Your document is never sent anywhere. The model comes to your document, not the other way round, which is the opposite of how every OCR service works.
