Convert scanned PDFs into fully searchable documents using Tesseract OCR, embedding a hidden text layer behind the original scan so you can search, copy, and index content without changing the visual appearance
Our free PDF OCR tool turns a scanned PDF into a fully searchable document in seconds. Right now a scan is just a picture of a page, you cannot search it, select it, or copy a single word. OCR fixes that by reading the text in the image and embedding it as a hidden layer behind the scan, so the file looks exactly the same but becomes searchable, copyable, and indexable. It runs on the proven Tesseract OCR engine, and it is completely free, with no signup and no watermark.
Making a scanned PDF searchable with File Tools Online takes three quick steps, and you do not need Adobe Acrobat or any desktop software. Everything runs online in your browser.
Drag and drop your PDF into the box above, or click to browse and select the file from your device.
Start the process. Tesseract reads the text in your scan and builds a hidden, selectable text layer behind each page.
Download the new PDF, it looks identical but you can now search and copy the text. Files are deleted within 30 minutes.
Open the result in any PDF reader and try searching for a word: it jumps straight to it. You can highlight and copy text, and search engines and document systems can finally index what is inside the file.
A scanned document is invisible to search, it is just pixels. Our OCR tool makes it usable again without changing a thing about how it looks, using an engine trusted in professional document workflows.
Built on Tesseract, one of the most widely used and accurate open-source OCR engines, for reliable text recognition on clear scans.
Turn a flat scan into a document you can search inside, copy text from, and have indexed by search and document systems.
The text layer is hidden behind the scan, so your PDF looks exactly the same, nothing about the visual appearance changes.

Files are processed securely over an encrypted connection and automatically deleted within 30 minutes.
Runs online on Windows, Mac, Linux, Chromebook, Android, and iPhone. Nothing to download and nothing to install.
OCR stands for Optical Character Recognition. When you scan a document or take a photo of one, the result is an image, the computer sees a picture, not words. OCR analyses that image, recognises the shapes of the letters, and converts them into real, machine-readable text.
This tool takes that recognised text and embeds it as an invisible layer aligned behind the original scan. The page still shows your exact scan, pixel for pixel, but underneath sits the text, so when you search or select, you are interacting with that hidden layer. The result is the best of both worlds: a document that looks like the original but behaves like a real text file.
Once a scanned PDF has been through OCR, a whole set of everyday tasks that were impossible before suddenly work.
File Tools Online offers more than 100 free tools to convert, edit, and manage your documents. These are the ones people use most alongside PDF OCR.
A lot of people looking for "PDF OCR to Word" really want two things: to make a scan readable, and then to edit it. Those are two separate steps, and doing them in order gives you the cleanest result.
Start here to OCR your scanned PDF, so it contains real text instead of just an image. Then run the searchable PDF through our PDF to Word converter to get an editable .docx, or our PDF to Excel converter to pull tables into a spreadsheet. Because the OCR step has already recovered the text, the conversion has something real to work with, instead of a flat picture that would otherwise come out empty.
One of the most useful things about this tool is what it does not change. Some OCR software re-flows your document, moves things around, or replaces the scan with reconstructed text that never quite matches the original. That is a problem for signed contracts, official forms, and any document where the exact appearance matters.
Here, your scan stays untouched on the surface. The recognised text is tucked invisibly behind it, so the file you download is visually identical to the one you uploaded, same layout, same signatures, same stamps, just now searchable underneath. You keep a faithful copy of the original while gaining all the benefits of real text.
Adobe Acrobat's "Recognize Text" feature does a good job, but it requires a paid Acrobat subscription installed on your computer. If you only need to make the occasional scanned PDF searchable, that is a lot of overhead for one task.
This tool gives you a free, online alternative. It runs the Tesseract OCR engine on our servers, so you get proper text recognition and a searchable PDF without paying for software, creating an account, or installing anything. Open the page, upload your scan, and download the searchable result.
OCR accuracy depends heavily on the quality of the scan you start with. A few simple things make a big difference:
Because this is an online OCR tool, it works the same on every device. There is no program to install on Windows, no app to download on Mac, and nothing to add to your phone, you use the exact same page whether you are on a laptop, a Chromebook, an Android device, or an iPhone.
That makes it easy to OCR a PDF on Mac, on a work computer where you cannot install software, or on your phone right after scanning a document with the camera. The recognition runs on our servers, so even a long scanned file is processed quickly no matter how powerful your own device is.
Yes. Scanned documents are often the most sensitive files people handle, IDs, contracts, medical and financial records, so security is built in. Files are uploaded over an encrypted HTTPS connection, processed on a secure server, and automatically deleted within 30 minutes. We never share, sell, or reuse your documents, and you do not need to create an account or hand over an email address to OCR a file.
OCR (Optical Character Recognition) reads the text in a scanned PDF and adds it as a hidden, selectable layer behind the image. Your scan becomes searchable and copyable while still looking exactly the same.
Upload your scanned PDF to the tool above and run OCR. It recognises the text and embeds it behind the scan, then gives you a searchable PDF to download, no retyping and nothing to install.
The File Tools Online PDF OCR tool is free to use, with no watermark added to your pages. Just upload the scanned PDF, run OCR, and download the searchable file, no signup required.
Yes. Once the file has been through OCR you can use Ctrl+F to search inside it, and you can select and copy any of the recognised text to paste elsewhere.
No. The recognised text is placed invisibly behind your original scan, so the downloaded PDF looks pixel-for-pixel identical to the one you uploaded, signatures, stamps, and layout are all preserved.
Do it in two steps: OCR the scanned PDF here first so it contains real text, then run the result through our PDF to Word converter. This gives a far cleaner Word file than converting a raw scan.
No. This is a free online alternative to Adobe Acrobat's text-recognition feature. It runs the Tesseract engine on our servers, so you get a searchable PDF with no paid software and nothing to install.
Accuracy depends on the quality of your scan. Clear, high-resolution scans of standard printed text produce excellent results; blurry, low-resolution, or skewed scans are harder to read accurately.
This tool is built for printed and typed text. For handwritten notes, use our dedicated Handwriting OCR tool instead, which is designed for that purpose.
Exactly the same way as on any other device: open this page in your browser on your Mac, upload the scanned PDF, run OCR, and download the searchable file. There is no separate Mac app to install.
Yes. Files are transferred over an encrypted connection, processed securely, and automatically deleted within 30 minutes. We never share or sell your documents.
OCR makes a scan searchable while keeping it as a PDF that looks the same. Converting to Word turns the content into a fully editable document. For scans, OCR first, then convert if you also need to edit.
Every day, huge numbers of documents are created by scanning paper or photographing it with a phone. They look fine, but they are effectively dead weight to a computer: you cannot search them, copy from them, or feed them into any system that works with text. OCR is what brings those documents back to life, recognising the characters in the image and turning them into real, usable text.
This free online PDF OCR tool uses the Tesseract engine to make your scanned PDFs searchable while leaving their appearance untouched. There is no account, no watermark, and no software to install, upload a scan, run OCR, and download a searchable PDF you can search, copy, index, and, if you need to, convert to an editable format. It is the essential first step for anyone working with scanned documents.
