OCR — Recognize Text in PDF Online Free
Make your scanned PDF searchable: add a text layer on top of the scan. Supports Russian and English. Tesseract 5 runs right in your browser — no external APIs and no upload.
Your file never leaves your computer: everything is processed in the browser, nothing is uploaded.
Three steps — and you're done
The entire process takes under a minute. No software to install, no account needed.
Upload your scanned PDF
Drop a PDF or click "choose a file." The tool works with scanned pages where text exists only as an image.
Select the language
Choose the primary language of your document: Russian, English, or both. This directly affects recognition accuracy.
Download the searchable PDF
The output PDF looks identical to the original but contains recognized text — fully searchable and ready to copy.
Secure, fast, and free
The principles we apply to every tool we build.
Files never uploaded
The document is processed inside your browser and never uploaded. You can see it yourself on the Network tab of the developer tools.
Works without the internet
Once the page has loaded, no connection is needed. Turn off the network and process a file — the tool keeps working. That is the simplest way to see the document goes nowhere.
No registration required
No account, email, or password needed. Upload a file and get your result instantly.
Works on any device
Fully optimized for phones and tablets — runs entirely in the browser.
