One of the suite's 8 professional tools. It takes a PDF or an image, detects personal data and returns an anonymized PDF. Everything described below (patterns, countries and methods) belongs exclusively to this tool. Detection works on multilingual text (ES, EN, FR, DE, IT, PT) and OCR reads scanned documents in Spanish and English.
Types of personal data the anonymization tool can automatically identify in your documents, such as:
Regions whose country-specific identity, tax and financial document formats the anonymization tool recognizes.
Available ways to hide or replace the data detected by the anonymization tool.
Languages available in the OléPDF interface. They apply across the whole suite, not just anonymization.
How the suite is built and why your documents stay safe.
Every tool processes the document locally in the browser. The document is never uploaded to any server.
The processing engines and anonymization models (AI detection, OCR, faces, codes) are served and executed from the same origin. No external processing API calls.
PDF (vector and scanned), JPG, PNG and WebP. Automatic OCR for scanned documents and images in the anonymization tool.
No information about processed documents is sent. The only network calls are loading the app, license verification (only the key, never the document) and contact forms.
