'Best PII Redaction Software in 2026'

'PiiBlur Team'7 min read

Choosing PII redaction software comes down to three questions: what personal information do you need to detect, do you process images or video or both, and how does the tool fit your workflow? Each tool makes different tradeoffs.

This guide compares eight PII redaction tools across detection categories, pricing models, video support, and API access. Public product pages change, so treat this as a buying shortlist rather than a substitute for testing each tool against your own media.

What to Look for in PII Redaction Software

Before comparing tools, know what matters for your workflow:

  • Detection categories - Some tools detect only faces and license plates. Others cover documents, QR codes, tattoos, and more. More categories means fewer gaps to fill manually.
  • Image and video support - One tool that handles both saves you from stitching together separate pipelines.
  • API access - Automated workflows require a REST API. Some tools restrict API access to higher-tier plans.
  • Pricing transparency - Flat-rate subscriptions make costs predictable. Pay-per-use models can surprise you at scale. Some vendors hide pricing behind a sales call.
  • Redaction methods - Blur and pixelation are standard. Some tools offer synthetic face replacements, which preserve facial attributes but add complexity.

1. PiiBlur

PiiBlur detects 13 categories of personal information in images and video: faces, license plates, screens, documents, street signs, ID cards, passports, credit cards, name badges, QR codes, barcodes, and tattoos. It redacts with blur or pixelation.

Key strengths:

  • Broadest detection coverage - 13 PII categories, more than any other tool on this list.
  • Images and video in one API - Process JPG, PNG, and WebP images alongside MP4, MOV, and WebM video up to 10 minutes through a single REST API.
  • Transparent pricing with a free tier - Plans start at $49/month for 5,000 images and 15 video minutes. The free tier includes 100 images and 5 video minutes per month with full API access. See all plans on the pricing page.
  • Developer-friendly - Webhooks, real-time dashboard status updates, batch processing, and a dashboard for non-technical team members.

Limitations:

  • Cloud-only. No on-premise deployment option.
  • Video length capped at 10 minutes per file.
  • No audio redaction.

2. Celantur

Celantur focuses on image anonymization for geospatial and mapping use cases. Its public API page lists faces, license plates, persons, and vehicles, with blur, pixelation, and blackening methods. It also advertises webhooks, object metadata, segmentation masks, pay-per-use pricing, and on-premise deployment through Celantur Container.

Key strengths: Strong fit for mobile mapping and street-level imagery. Public pay-per-use image pricing is useful for teams that prefer variable cost over a subscription. Metadata and segmentation masks are valuable if anonymization output feeds another computer-vision pipeline.

Limitations: The public API page is image-focused and lists four detection classes, so teams that need documents, QR codes, tattoos, screen content, or a single image/video subscription should compare carefully.

3. Brighter AI

Brighter AI specializes in face anonymization using Deep Natural Anonymization (DNAT), which replaces real faces with synthetic ones that preserve attributes like gaze direction, expression, and age. It also detects license plates and persons.

Key strengths: DNAT is unique in this market - if you need to anonymize faces while preserving natural appearance, Brighter AI is the specialist. Supports on-premise, edge, and Kubernetes deployment.

Limitations: Detects only 3 PII categories. Pricing requires a sales conversation. The free trial lasts 14 days, compared to ongoing free tiers elsewhere.

4. Secure Redact

Secure Redact (by Pimloc) is a broad redaction platform for video, audio, images, documents, and PDFs. It is especially visible in law enforcement, surveillance, and body-worn camera workflows, and public pages describe SaaS, API, private cloud, on-premise, and enterprise options.

Key strengths: Strong fit for security, legal, and evidence workflows that need review tooling, audio redaction, private deployment, or one platform for several file types. Secure Redact's credit model can cover video, audio, images, and documents.

Limitations: The platform is broader and more workflow-heavy than a simple developer API. If you only need visual PII redaction for application uploads or batch media pipelines, compare the operational fit and credit pricing against a purpose-built image/video API.

5. Gallio

Gallio is desktop software for Windows, macOS, and Linux. It processes files locally on your GPU and detects faces and license plates.

Key strengths: Fully local processing with no cloud dependency. A single license purchase removes all per-image and per-video limits - you process as much as your hardware allows. Supports 4K and 8K video.

Limitations: Detects only 2 PII categories. Desktop-only with a single-computer license - no team collaboration or API access unless you buy the enterprise Docker tier. The free demo watermarks output and caps resolution at 720p.

6. Watermarkly

Watermarkly offers a lightweight Blur API that detects faces and license plates in images at $0.01 per image through AWS Marketplace.

Key strengths: Pay-as-you-go pricing with no monthly commitment. Supports many input formats including AVIF and HEIC. Easy entry point for small-volume use cases.

Limitations: Images only - no video. Detects 2 PII categories. No dashboard, webhooks, or pixelation option. At high volumes, costs climb fast: 100,000 images costs $1,000/month versus $499/month on PiiBlur for the same volume plus video and 13 detection categories.

7. BlurIt

BlurIt publishes API documentation for an anonymization platform that blurs faces and license plates in images and videos. Public docs describe REST-style endpoints, JSON responses, and token-based authentication.

Key strengths: Clear fit for teams whose anonymization scope is faces and plates. Image and video API coverage makes it more relevant to developer teams than browser-only editors.

Limitations: Public documentation focuses on faces and license plates. Pricing, webhooks, and broader PII categories are not as visible publicly as they are for some alternatives.

8. PixBlur

PixBlur is a browser-first image blur and pixelation editor with AI-assisted face, license plate, and sensitive text redaction. It positions manual editing as free and AI redaction as credit-based.

Key strengths: Good fit for one-off image edits where a human wants direct control in the browser. The manual editor workflow is useful for occasional redaction without an API integration.

Limitations: Public pages focus on images and editor workflows, not backend API automation or video redaction. Teams building recurring upload, moderation, claims, or dataset pipelines will usually need a programmatic API instead.

How to Choose the Right PII Redaction Tool

Your decision depends on three factors:

What PII types do you need to detect? If faces and license plates suffice, most tools here will work. If you need documents, QR codes, tattoos, screen content, or ID cards, only PiiBlur covers all of them.

Do you process video, images, or both? Watermarkly and PixBlur are image-first. PiiBlur, BlurIt, Brighter AI, and Gallio cover both images and video in different ways. Celantur's public API page is image-focused, while Secure Redact covers several media types through a broader redaction platform.

How does the tool fit your workflow? For a cloud API with webhooks, PiiBlur and Celantur are the most visible self-serve options. For on-premise processing, Celantur, Brighter AI, Secure Redact, and Gallio may fit better. For manual one-off edits, PixBlur is closer to an editor than an API.

For teams processing a mix of images and video with diverse PII types, PiiBlur offers the broadest coverage at predictable pricing. Start with the free tier to test it against your own media before committing.
