Practical, honest guides on redacting and cleaning PDFs without uploading them — done in your browser, where your files never leave your machine.
Every guide here is plain-English and vendor-honest: what to black out, how to actually destroy it (not just cover it), and how to prove the file is clean before you send it.
Why box-over-text "redaction" leaks (Manafort, Epstein files) and what true destructive redaction is.
→ 02Black out words so they can't be copied back out.
→ 03Redact locally and prove nothing was uploaded.
→ 04Why Preview's black box isn't enough, and what works.
→BlackoutPDF removes the content instead of covering it: pages are re-rendered to pixels and rebuilt into a fresh PDF, so there's no text layer left under the black and metadata is stripped. It all happens in your browser — your document never leaves your machine. Free for short files.
