Make a scanned PDF searchable and copyable.

Text recognition (OCR) reads the words on every scanned page and adds them as an invisible text layer. The pages look exactly the same, but you can search, select and copy the text – all in your browser.

Scanned pages get an invisible, searchable text layer

Guideline: up to 50 MB works well on most devices; for larger files a computer is more reliable than a phone. Check for yourself that your files aren't uploaded

    Language of the document

    Choose up to 3 languages. Each language is downloaded once, the first time you use it (0.7–3 MB).

    Takes a few seconds per page; a long scan can take minutes.

    How to make a scanned PDF searchable

    1

    Choose your scanned PDF

    Drag it into the tool or click to browse. Your file isn't uploaded: your browser reads it itself.

    2

    Pick the language

    The language of this page and English are ticked; choose up to 3. Pages that already have text are skipped unless you choose All pages.

    3

    Download the searchable PDF

    Every page looks exactly as before, with the recognised text invisible on top: search it with Ctrl+F, select it or copy it.

    Tips for good text recognition

    Straight, sharp scans work best

    Scan at 300 dpi in black and white or grey and keep the pages straight. Turn sideways pages first with Rotate PDF: a page that is upside down is read as nonsense.

    Choose the right languages

    The language decides which letters and words are expected: with French chosen, é and ç come out right. More languages make it slower and can cause mistakes, so choose only what the document contains.

    Pages with text are left alone

    A page that already has selectable text is skipped, so a mixed PDF doesn’t get its text twice. Choose All pages for a page whose existing text layer is wrong.

    Check the result

    Recognition is never flawless: a blurry scan, small print, tables or unusual fonts cause mistakes, and handwriting usually fails. Check the result before you rely on it. The first time, the recognition engine and the languages are downloaded (about 2 to 10 MB).

    Questions about OCR

    How do I make a scanned PDF searchable?

    Drop the PDF into the tool above, check the language and click Make searchable. The pages are recognised one after another, and the searchable PDF downloads when it’s done.

    Is my scan uploaded for the text recognition?

    No. The recognition engine (Tesseract) runs in your browser; it and the language data are downloaded from this site, and your files aren’t uploaded.

    Does the PDF look different afterwards?

    No. The original pages stay exactly as they were: the recognised text is added as an invisible layer on top, in the right place, so you can select and search it. The file gets only slightly bigger.

    Which languages are supported?

    English, Dutch, French, German, Spanish, Portuguese, Italian and Polish, with their accents. You can combine up to 3 languages for a document that mixes them.

    Why are some words wrong?

    OCR guesses each word from the image. Blurry or skewed scans, very small text, stamps, tables and handwriting cause mistakes. A clean scan at 300 dpi helps; for important documents, always check the text.

    How long does it take?

    A few seconds per page on a computer, longer on a phone. A 50-page scan can take several minutes; keep the tab open. You can cancel at any time.
