Redact sensitive data
offline
Keep every document private with fast, offline redaction.
Manual redaction is slow, error-prone, and one missed detail can leak sensitive data. Reducto automatically detects and masks names, phone numbers, emails, bank details, credit card numbers, SSN, Indian PAN and more - across PDFs, Excel spreadsheets, and Word documents.
- No signup required
- Processed on-device
- PDF, Excel & Word supported
Everything you need to redact with confidence
Reducto combines blazing-fast automated detection with the pixel-perfect manual precision professional teams actually rely on - across PDF, Excel, and Word files.
Data stays on your computer
Your PDFs, Excel sheets, and Word documents are processed entirely on your device. Nothing is uploaded, stored, or shared with the cloud, ensuring complete privacy and control.
Live preview
Watch redactions applied in real time as you toggle categories across PDF pages, Excel cells, or Word paragraphs. Catch errors before you hit export.
Manual control
Mask extra text with a click-and-drag, replace redactions with custom labels, or fine-tune exactly what the AI missed - in any supported file type.
Batch processing
Drop an entire folder of PDFs, Excel workbooks, or Word documents and redact them all together with consistent rule sets in a fraction of the time.
Undo & restore
Revert any individual redaction - even after saving a draft - with our secure, flexible internal restore log.
Privacy first
Files are processed locally on your machine or in an isolated secure sandbox. Nothing is ever stored without your consent.
Three steps. Zero friction.
From a raw upload to a fully secure, redacted file in under a minute - whether it's a PDF, Excel sheet, or Word document.
Upload your file
Drag & drop a PDF, Excel, or Word file - or browse. We support single large documents or zipped folders for bulk processing.
Choose what to mask
