Top 5 Best Redaction Software for Redacting Sensitive Data in Files (Reviewed in 2025)

Data breaches are getting more expensive and more personal. IBM’s 2024 Cost of a Data Breach report found that nearly 46 percent of all breaches involve customer personally identifiable information (PII) such as names, IDs, emails, and addresses.

When that kind of data is buried across contracts, police reports, medical records, emails, videos, and call recordings, manual black boxes in PDFs are no longer enough. Organizations now look for AI-powered redaction software that can quickly and securely remove sensitive data from every kind of file they handle. 

In this 2025 guide, we review the 5 best redaction tools for securely redacting sensitive data in files, highlighting where each solution fits best, and explaining why VIDIZMO Redactor stands out as an all-in-one choice for multi-format AI-assisted redaction. 

What Is AI Redaction Software and Why It Matters in 2025

AI redaction software uses machine learning, OCR, and pattern recognition to automatically detect and permanently remove sensitive information such as: 

• Names, addresses, IDs, SSNs, phone numbers, and emails 
• Protected health information 
• Financial data,  such as card and account numbers 
• Internal or confidential business information 

Modern platforms do this across multiple file formats, including PDFs, Word files, spreadsheets, images, videos, and audio, while helping teams meet compliance requirements like GDPR, HIPAA, CCPA, FOIA, and DSAR workflows. 

Instead of manually drawing boxes over text, these platforms can: 

• Auto-detect faces, license plates, screens, and objects in video 
• Identify names, IDs, numbers, and PII in documents and images 
• Detect and mute spoken names or numbers in audio and video 

This combination of automation and auditability defines the best redaction software in 2025.
