🛡️ Queima Permanente

The black stripes will be written directly into the PDF's graphic layer, preventing selection or copying of hidden text.

Why use Onflip Permanent Anonymization?

1. No Layer Leakage

Unlike regular editors that just place a black rectangle on top with selectable text underneath, we physically cover the data in the final file.

2. Detecção Automatizada

Save hours of manual work reviewing pages: CPF, CNPJ and contact patterns are located and marked in seconds.

3. Privacidade Absoluta

Processing performed in the local RAM of your computer or cell phone. Your sensitive documents never leave your device.
