How to OCR a PDF
Upload Scanned PDF
Drop the scanned PDF you want to make searchable.
Choose Language and Output
Pick the document language and whether you want a searchable PDF or plain text.
Run OCR and Download
Text is recognized page by page, then embedded or exported.
Unlock the Words in Scanned Documents
Scanned PDFs are pictures of pages — the words inside cannot be searched or copied. OCR turns them into real, usable text.
Because the whole process runs on your device, you can OCR confidential contracts and records without sending them anywhere.

Frequently asked questions
What is a searchable PDF?
A PDF that still looks like a scan but contains a hidden text layer. You can search, copy, and select the words as if it were a digital document.
Which languages are supported?
English, Spanish, French, German, and Portuguese at launch. More languages can be added easily.
Is my file uploaded for OCR?
No. Everything runs in your browser. The OCR engine itself downloads its language data from a public CDN, but your file never leaves your device.
