      How the result looks

      Fully removed — not just covered

      Black, colored or highlighted marks actually remove the content from the file — four styles, three redaction methods.

      Overview

      What is Docuflair Redact?

      Docuflair Redact is an audit-proof redaction tool for businesses, public authorities and law firms. With the free online demo you can remove sensitive content (names, email addresses, IBAN, dates of birth, ID numbers) from PDF, Word, Excel and over 100 other file formats — directly in your browser, without installation and without registration.

      How it works

      Three steps to a redacted document

      1
      Upload
      Drag one or more files into the upload area or select them via the dialog.
      2
      Review
      Check and refine the automatically detected personal data, or redact your own regions by clicking.
      3
      Download
      Save the final redacted document — black marks actually remove the content, not just hide it visually.

      FAQ

      Frequently asked questions

      Are my files stored permanently?

      No. Demo uploads are kept in memory only for the duration of the session and deleted afterwards. With the licensed on-premises edition, you decide on retention yourself.

      Which personal data is detected automatically?

      Email addresses, IBAN/BIC, phone numbers, postal addresses, personal names, dates of birth, ID and tax numbers as well as IP addresses. Custom terms and regex can be added.

      Does redaction also work on scanned PDFs?

      Yes. The built-in OCR (text recognition) processes scans and images, so embedded text can also be detected and redacted.

      Can I use Docuflair Redact in my company?

      Yes. A license is required for productive use with multi-user, full-text search, long-term archiving and audit logging. You can find details and pricing at docuflair.com/preise/schwaerzung.

      Is redaction truly irreversible?

      Correct. Unlike a black rectangle placed over the text, the original content is deleted from the file and replaced by the redaction pattern. Metadata and comments are cleaned up as well.

      Privacy & terms of use (Demo)

      Provider of the demo: Administrator.at B2B GmbH (hereinafter "the Provider"). By ticking the checkbox, the user expressly confirms the following terms for the use of the free online demo:

      1. Purpose limitation & user responsibility. The demo serves exclusively for non-binding testing and evaluation of the redaction feature. The user uploads documents at their own responsibility and warrants that they are authorized to transmit their contents to the Provider for processing purposes. Personal data of third parties may only be uploaded if the user has an independent legal basis for doing so — the Provider cannot verify this authorization and accepts no responsibility for it.
      2. No permanent storage. Uploaded documents and the redaction results generated from them are held exclusively transiently in the session storage of the demo environment and are automatically and irrevocably deleted at the latest when the demo session expires (typically 30 minutes of inactivity). No permanent storage, backup, or archiving of the content takes place.
      3. No analysis, no disclosure, no AI training. The Provider does not analyze the transmitted document contents for its own purposes, does not disclose them to third parties, and uses them neither to improve the software nor to train AI models or pattern-recognition libraries. Only technically unavoidable connection data (IP address, timestamp, user agent) are processed to ensure operation and to prevent abuse.
      4. Free of charge, no guaranteed availability. The demo is provided free of charge and without any guaranteed availability, performance, or depth of functionality. The Provider reserves the right to restrict, interrupt, or discontinue demo operation at any time and without prior notice. There is no entitlement to the restoration of lost session data.
      5. Disclaimer of liability to the extent permitted by law. Use of the demo is at the user's own risk. Liability of the Provider — in particular for incomplete, erroneous, or inadvertently omitted redactions, for indirect damages, lost profits, data loss, reputational damage, or consequential damages arising from the further use of the demo results — is excluded to the extent permitted by law. The user is obligated to independently verify each result for completeness before any productive further use.
      6. Provisions remaining unaffected. The statutory liability of the Provider for intent and gross negligence, for damages arising from injury to life, body, or health, for the breach of essential contractual obligations, as well as under mandatory provisions of consumer protection law and the GDPR, remains unaffected.
      7. Production use. Production use with real personal data requires a licensed on-premises or managed installation, in the context of which the Provider will, upon request, conclude a data processing agreement pursuant to Art. 28 GDPR.
