Best alternatives to Masker in 2026
When you black out sensitive information in a PDF using many common tools, the underlying text often stays exactly where it was — anyone can select it, copy it, or extract it with a script, even though it looks hidden. Masker is a free macOS app built to close that gap: it detects sensitive text like Social Security numbers, tax IDs, emails, and phone numbers, lets you search for anything else you want to hide, and then permanently rasterizes the page into a flat image. Once a document is processed, there is no text layer left underneath the black box, and nothing is ever uploaded to a server — everything happens on your own Mac. Under the hood, Masker is a native Swift app built with SwiftUI, PDFKit, Vision, and Core Graphics, with no third-party dependencies. Detection combines case-insensitive pattern matching with word-boundary checks and automatic recognition of SSNs, EINs, emails, and phone numbers, backed by OCR caching for scanned pages. A Discovery Mode recursively scans folders to find PDFs containing sensitive patterns, and batch conversion applies redactions across many files at once. Mask sets can be exported and imported as generic JSON, and an optional MCP companion lets AI workflows drive the redaction process programmatically.
