Making a scanned PDF text-selectable with FreeConverto takes under two minutes and requires no software download or sign-up.

Frequently Asked Questions
Why can't I select text in my scanned PDF?
Scanned PDFs are images — photographs of a page — not real text documents. There is no actual text data in the file, only pixels arranged to look like letters. That is why selecting, copying or searching the text is impossible. OCR (Optical Character Recognition) reads the image and adds a real, invisible text layer at the exact position of every word, so you can select and copy text just like a native PDF.
Can I select and highlight text in the downloaded PDF?
Yes — that is exactly what this tool does. It adds an invisible text layer word-by-word at the precise position of each word on every page of your original PDF. Open the downloaded file in Adobe Acrobat, Chrome, Safari, Edge, or any iOS or Android PDF viewer and you can select words, highlight passages, and use Ctrl+F (or Cmd+F on Mac) to search any phrase instantly. The document looks completely identical to your original scan — only the text becomes selectable.
What is OCR and why do I need it for a scanned PDF?
OCR (Optical Character Recognition) converts scanned images of text into real, machine-readable text. Scanned PDFs are essentially pictures — you cannot search, copy or highlight the text inside them without OCR. Running OCR adds an invisible, selectable text layer so you can Ctrl+F, select words and copy paragraphs without changing the visual appearance of the document at all.
How do I make a scanned PDF text-selectable and searchable online for free?
Upload your scanned PDF to FreeConverto, choose your document language from the dropdown, then click Run OCR. The tool recognises every word with its exact on-page position and embeds an invisible text layer directly onto your original PDF pages. Download the result — text is now selectable, copyable, highlightable and Ctrl+F searchable in any PDF viewer. No sign-up, no server upload, no watermark, completely free.
How do I extract text from a scanned PDF without any software?
Use FreeConverto's free online OCR PDF tool — no software download or installation required. Upload your scanned PDF, select the document language, click Run OCR, then copy the extracted text from the panel on screen or download it as a .txt file. The downloaded PDF also has a selectable text layer. Works on Windows, Mac, iPhone and Android.
Will my scanned PDF be uploaded to a server?
No — all OCR processing runs entirely in your browser using the open-source Tesseract.js library. Your scanned file never leaves your device, is never sent to any server and is never stored or seen by anyone. This makes it safe for sensitive documents such as contracts, medical records, legal filings and financial statements.
Does OCR change the appearance or layout of my PDF?
No — this tool loads your original PDF pages and copies them exactly as they are. It then adds only an invisible text layer at the position of each recognised word. The visual appearance, layout, formatting, images and page structure of your document are completely unchanged after OCR.
Can I make a scanned PDF text-selectable on iPhone or Android?
Yes — the tool works on iPhone, iPad, Android and any device with a modern browser. Open freeconverto.com/ocr-pdf/ in Safari on iPhone or Chrome on Android, upload your scanned PDF and run OCR. The downloaded PDF will have a selectable text layer that works in Apple Files, Google Drive viewer, Adobe Acrobat Mobile and other PDF viewer apps.
What is the best render quality setting for accurate text selection?
Standard (2×) works well for most clearly printed, cleanly scanned documents. Choose High (3×) for faded documents, documents with small font sizes, old typewritten text, or anything with fine detail — it takes longer but gives better OCR accuracy and more precise word positions in the text layer. Use Fast (1.5×) for large multi-page documents where speed matters more than precision.
What other free PDF tools does FreeConverto offer?
FreeConverto offers a complete suite of free browser-based PDF tools including a PDF merger, PDF splitter, PDF rotator, PDF compressor, PDF watermark tool, PDF to JPG converter and PDF unlocker. All completely free with no sign-up and no upload to any server.
