Foxit PDF SDK for Web

Foxit PDF SDK for Web: Redaction

Programmatically search and sensor sensitive information in a document for legal or security purposes to keep customer and employee information safe. Achieve full GDPR-compliance with Foxit’s powerful technology.

Our redaction module applies annotations to block sensitive information in a document. Only a dark line will show in the place of the content in the front-end and no sensitive data is kept in the meta information. Our technology utilizes a process that ensures redacted material is deleted and the blacked out (redacted) areas become images, stopping someone being able to access the sensitive information underneath.

Take a look at the sample code below to get started with redacting a defined area of a PDF.
