How to make a scanned PDF searchable

Drop your PDF in the box, choose the language of the text and press Make searchable. Wait while each page is read, then download the new PDF. The text is also given as a separate .txt file.

The first time, the reading engine and the language are downloaded (a few megabytes). This is the one thing this tool downloads; your PDF never leaves your device.

Common mistakes

  • Choosing English for a Hindi or Marathi scan: the result is nonsense. Choose the language of the text.
  • Reading pages that already have real text: they get a second, hidden text layer. Choose only the scanned pages.
  • Very blurry, tilted or handwritten pages are read badly. A sharper scan gives better results.
  • A PDF with a password: remove the password first, the tool cannot open it.

Frequently asked questions

Is my PDF uploaded?
No. Every page is read on your device. The only thing downloaded is the reading engine and the language data, once, from a public content network (jsDelivr). Your browser keeps them for next time.
What does a searchable PDF look like?
It looks exactly like your scan. Behind each word there is invisible text, so you can search with Ctrl+F, select words and copy them.
Does it work for Hindi and Marathi?
Yes, choose the language before you start. The reading is as good as the scan: clear, straight pages with dark text work best. Search and copy of Hindi and Marathi text depends on your PDF viewer; the text is also saved in a separate .txt file so you always have it.
Why is it slow?
Reading a page is hard work for the browser. Expect several seconds per page. You can press Cancel at any time and nothing is saved.
Will pages that already have text be doubled?
The tool does not check. If only some pages are scans, choose just those pages so you do not add a second text layer to the others.
Is my PDF uploaded?
No. Only the reading engine and the language data are downloaded the first time (a few megabytes); your PDF stays on your device.
