Redact PDFs without uploading them anywhere

Get picks like this daily. Today's launch numbers, the top launches, AI and tech news, and a daily opportunity pick, straight to your inbox.

Want to reach these readers? Sponsor an issue.

Drop in a PDF and hddn opens it in your browser. Nothing is uploaded for processing. It highlights names, emails, IDs and numbers for you to approve, you can black out anything else by hand, and the export removes the covered content from the file instead of painting over it. Load it once and it keeps working with your Wi-Fi off. That is the whole pitch, and you can test it in about thirty seconds.
