Excise vs PineThink Redact

Excise is a free, open-source PDF editor for Windows, macOS, and Linux. Its central feature is permanent redaction: it removes text, images, and vector graphics from PDF content rather than placing a visible cover over them. By default, the cleanup also removes metadata, attachments, JavaScript, thumbnails, and hidden layers, and reports those removals. The app handles search, text selection and copying, annotations, page organization, Bates numbering, file-size reduction, and AcroForm filling, flattening, and creation. Its command-line tools support batch work and stable JSON output; `unredact` checks for leaked redacted text, while `audit` looks for text beneath opaque overlays. Excise reads and writes AES-128 and AES-256 encryption and inspects digital signatures against the operating system trust store. Signature inspection does not check revocation or evaluate timestamp and long-term validation material. Dynamic XFA layouts are experimental and cannot be filled. Downloads include packages for Apple Silicon macOS, Windows 10/11 x64, Ubuntu/Debian, and x64 or ARM64 Linux; builds are unsigned, not notarized, and lack auto-update.

PineThink Redact is a desktop app for finding and removing personal information from PDFs, Word documents, and scans. It detects names, addresses, phone numbers, SSNs, account and card numbers, dates of birth, and medical details, and supports custom terms. Users review detections before removal. Instead of placing a black cover over sensitive text, the app deletes it from the file’s content. Detection, review, and redaction take place on the user’s PC; documents are not uploaded. Built-in OCR reads scanned documents, including image-only PDFs. The free tier permits one document at a time for personal use and needs no account. Premium costs $6.99 a month after a free 14-day trial. It adds folder-based batch redaction, saved settings, custom term lists, per-file audit reports, commercial use, and AI agent access through MCP. The app requires internet for activation and periodic subscription checks, but works offline between checks. PineThink says anonymous usage statistics contain no file content and can be turned off in settings.
