Get started with just a few lines of code
import requests
api_key = "your_api_key"
url = "https://api.redactionapi.net/v1/redact"
data = {
"text": "John Smith's SSN is 123-45-6789",
"redaction_types": ["ssn", "person_name"],
"output_format": "redacted"
}
response = requests.post(url,
headers={"Authorization": f"Bearer {api_key}"},
json=data
)
print(response.json())
# Output: {"redacted_text": "[PERSON_NAME]'s SSN is [SSN_REDACTED]"}
const axios = require('axios');
const apiKey = 'your_api_key';
const url = 'https://api.redactionapi.net/v1/redact';
const data = {
text: "John Smith's SSN is 123-45-6789",
redaction_types: ["ssn", "person_name"],
output_format: "redacted"
};
axios.post(url, data, {
headers: { 'Authorization': `Bearer ${apiKey}` }
})
.then(response => {
console.log(response.data);
// Output: {"redacted_text": "[PERSON_NAME]'s SSN is [SSN_REDACTED]"}
});
curl -X POST https://api.redactionapi.net/v1/redact \
-H "Authorization: Bearer your_api_key" \
-H "Content-Type: application/json" \
-d '{

In today's digital workplace, sensitive data exists across an ever-expanding variety of document formats. From traditional office documents to multimedia files, from structured data exports to scanned paper archives, organizations must protect sensitive information wherever it resides. Effective data protection requires redaction capabilities that span this entire document landscape without requiring different tools for different formats.
RedactionAPI provides unified redaction across 50+ document formats through a single API. Whether you're processing PDFs, Word documents, spreadsheets, images, audio recordings, or video files, the same API calls and redaction rules apply. This simplifies integration, ensures consistent protection, and eliminates the need to maintain multiple redaction solutions.
Our document processing goes beyond simple text extraction. We understand document structure, preserving the relationship between content elements while applying appropriate redaction. Headers, footers, tables, lists, and other structural elements are maintained in the output, ensuring redacted documents remain usable and professional.
For documents containing multiple content types—like PDFs with embedded images or presentations with audio narration—we process each content type appropriately. Embedded images undergo OCR and visual redaction. Audio tracks are transcribed and analyzed. The result is comprehensive protection across all information channels within a document.
Many organizations maintain large archives of scanned documents that may contain sensitive information. These documents present unique challenges: the text exists only as pixels in an image, invisible to traditional text-based redaction tools. Our OCR technology addresses this challenge with high accuracy across document types and languages.
Our neural network-based OCR achieves 99%+ accuracy on standard document scans and maintains high accuracy even with challenging inputs like faded text, skewed pages, mixed fonts, and handwritten annotations. Support for 150+ languages means global document archives can be processed without language-specific configuration.
Effective redaction must protect sensitive data while preserving document usability. A heavily processed document that loses formatting, structure, or quality serves no one's needs. Our processing pipeline prioritizes document integrity throughout the redaction process.
For text documents, we maintain fonts, styles, pagination, and layout. For images, we preserve resolution and quality outside redacted regions. For audio and video, we maintain synchronization, quality, and metadata. The goal is output documents that appear and function identically to originals except for the appropriately redacted sensitive content.
RedactionAPI has transformed our document processing workflow. We've reduced manual redaction time by 95% while achieving better accuracy than our previous manual process.
The API integration was seamless. Within a week, we had automated redaction running across all our customer support channels, ensuring GDPR compliance effortlessly.
We process over 50,000 legal documents monthly. RedactionAPI handles it all with incredible accuracy and speed. It's become an essential part of our legal tech stack.
The multi-language support is outstanding. We operate in 30 countries and RedactionAPI handles all our documents regardless of language with consistent accuracy.

We support 50+ formats including: PDF (native and scanned), Microsoft Office (Word, Excel, PowerPoint), images (JPG, PNG, TIFF, BMP, GIF), audio (MP3, WAV, M4A, FLAC), video (MP4, AVI, MOV, MKV), plain text, HTML, XML, JSON, CSV, and many more. Contact us if you have a specific format not listed.
Our OCR engine uses advanced neural networks to extract text from scanned documents and images with 99%+ accuracy. It handles various scan qualities, skewed pages, handwritten text, and documents in 150+ languages. Extracted text is then processed for sensitive data detection.
Yes, we preserve original document formatting wherever possible. For PDFs, we maintain layout, fonts, and structure. For Office documents, we preserve styles, headers/footers, and embedded objects. For images, we maintain resolution and quality outside redacted areas.
Yes, our PDF processing handles embedded images. We extract images, run OCR if needed, detect sensitive data, and apply visual redaction. The redacted image is re-embedded in the PDF, maintaining document structure.
For audio, we transcribe the content using speech-to-text, identify sensitive information in the transcript, and can either provide the redacted transcript or mute/beep sensitive audio segments. For video, we combine audio processing with visual analysis to detect on-screen text and faces.
We can process password-protected documents if you provide the password. For documents with DRM or other protection, we need appropriate permissions. We maintain encryption on output documents using your specified passwords or encryption settings.
