Examples

1. Replace-style Anonymization

Background
A HR manager needs to share a set of candidate evaluation forms with an external consultant.
Problem
The forms contain private email addresses and phone numbers that must be removed for privacy.
How to Use
Upload the PDF, select 'Replace Label' as the mask style, and process the file.
Example Config
{"detectNames": true, "maskStyle": "replace", "drawReportBadge": true}
Outcome
The PDF is generated with sensitive fields replaced by clear labels, and an anonymization badge is added to the document.

2. Blur-style Anonymization

Background
A researcher is publishing a document that includes sensitive client names.
Problem
The researcher needs to hide the names completely without leaving any readable text or labels behind.
How to Use
Upload the PDF, select 'Blur Block' as the mask style, and disable the report badge for a cleaner look.
Example Config
{"detectNames": true, "maskStyle": "blur", "drawReportBadge": false}
Outcome
The names are obscured by blur blocks, ensuring the information is unreadable while maintaining the document's original layout.
