A tool born from a simple need: sharing a document without sharing what's inside it.
Every day, teams send documents that contain more than they should: a contract with a client's address, a payslip with a bank account, a scan of an ID card, an export full of email addresses. Redacting them by hand is slow. Uploading them to an online service means trusting someone else with the very data you wanted to protect.
ONYRI Sanitize takes another route. You drop a PDF, a Word file or a scan. The tool reads it, finds the sensitive data — names, emails, phone numbers, bank details, ID numbers, API keys — and masks it, layout intact. You check the preview, then download the anonymized copy. It takes seconds.
The architecture is deliberately simple. Everything — reading the file, recognizing text in a scan, detecting, masking, exporting — runs in your browser. Our servers only handle your account, your plan and your detection settings. They never see a document. That is a design choice, and you can verify it in your browser's developer tools.
ONYRI Sanitize is a project by ONYRI Strategy, an independent consulting firm in data strategy and security.
What we stand by
The document is the product
One job, done well: an anonymized document, in seconds, that still looks like the original.
Nothing leaves your device
No upload, no server-side processing, no content in our logs. Our servers count documents; they never read them.
Honest about limits
Automatic detection is not exhaustive, and masking reduces exposure rather than guaranteeing compliance. That's why you review the preview before you download.
