Redenta
Runs on your device — files are never uploaded

Redact a document

Remove sensitive content from a PDF, Word, Excel, Markdown, HTML, text or image file. Redenta rebuilds the file so the redacted content is truly gone from the bytes — recoverable neither by copy-paste nor a byte inspector. Everything happens on your device.
