What you can do with OCR PDF
OCR reads the text inside a scanned PDF and adds a searchable, selectable text layer behind the image, turning a picture of a document into one you can search, copy from, and highlight.
Search a scanned contract
Make an image-only scan searchable so you can jump straight to a clause or a name.
Copy text from a scan
Pull quotes, figures, or addresses out of a scanned page without retyping them.
Archive documents properly
Turn a folder of scans into searchable PDFs so they are findable later.
Improve accessibility
Add a real text layer so screen readers can read a document that was previously just an image.
A more secure model for OCR PDF
The weakest point in most online PDF workflows is the round trip to a server: the upload can be intercepted, the server can be compromised, and copies can linger in logs, caches, or backups long after you are done. Adding TLS helps in transit, but it doesn't protect the copy that ends up sitting on the provider's disk.
ContinuePDF's approach is to not send the file anywhere. The OCR logic runs inside your browser's sandbox, isolated from other sites and from the wider system. Your scanned PDF exists only in your device's memory while the tool works, which shrinks the attack surface to essentially zero — there is no server component to breach.
Why choose ContinuePDF
No transmission
The file is never sent over the network, so it can't be intercepted.
No retention
Nothing is stored server-side — no logs, caches, or backups of your file.
Sandboxed
Processing runs inside the browser's isolated security sandbox.
Minimal surface
No server component means there is nothing on our side to attack.
Pro tip
Cleaner scans give far better results — straighten pages and use good contrast before running OCR. Choosing the correct language for the document improves accuracy, especially for accented characters.
Frequently asked questions
Does OCR change how my document looks?
No. The original scanned image stays exactly as it is; OCR adds an invisible text layer behind it, so the page looks identical but is now searchable and selectable.
How accurate is the text recognition?
Accuracy is high for clear, straight, high-contrast scans and lower for blurry, skewed, or handwritten pages. It is wise to review the result if you will rely on the extracted text.
How is this more secure than other OCR PDF tools?
Most tools upload your file to a server, creating a copy that can be intercepted, logged, or breached. ContinuePDF processes your scanned PDF inside your browser, so the document is never transmitted and no server-side copy is ever created.
Are my files stored anywhere after I OCR them?
No. Because the file never leaves your device, there is nothing stored on our end. The document lives only in your browser's memory during processing and is cleared when you close the tab.
Is ContinuePDF free to use?
Yes. ContinuePDF and all of its tools, including OCR PDF, are free with no signup required. Because documents are processed in your browser rather than on our servers, we can offer the full feature set at no cost.
