OCR · In your browser

A scan is a confession. This one stays in the room.

Falcon OCR is an optical-character-recognition tool that makes a scanned PDF searchable. The OCR engine runs inside the browser tab and does not access the network during processing. The scan and the resulting searchable PDF both stay on your computer.

The scanned PDF opens in this tab. The OCR engine runs on your computer; the searchable PDF is written here. By design.

Why this tool exists

A scanned document is almost always more sensitive than the same document was when it was a Word file. Scans are usually of paper — letters, ID cards, contracts, medical results, things printed on letterhead. The act of scanning is also the act of preparing to share. The OCR step, on most online tools, is what shares it first.

When the OCR engine runs in this tab, the scan does not move at all. The image of every page is held in memory on your computer. The text is recognised here, added back to the PDF as an invisible searchable layer, and written to the file you download. The letter, the ID card, the contract — they leave in their own time, in your hands.

FAQ

Common questions

Does my scanned document leave my device for text recognition?

No. The recognition engine runs inside this browser tab and does not touch the network while it works. A scan can be the most sensitive thing you hold — here it stays in the room, and so does the searchable file it becomes.

What does this add to my scanned PDF?

A searchable, selectable text layer behind the scanned images, so you can find words, copy text, and let a reader jump to a match. The scan becomes a document you can work with rather than just a picture.

Does it change how my scan looks?

No. The page images are left untouched; the recognised text sits behind them, invisible but selectable. What you see is the same scan — what changes is that it can now be searched.

Which language does the recognition read?

English text. A clean, upright, high-contrast scan of English-language pages is what the engine reads best.

How accurate is the recognition?

It depends on the scan. Sharp, straight, well-lit pages recognise cleanly; faint, skewed, or low-resolution scans are harder and will carry more mistakes. Better input gives a better text layer.
