In their own words
BleachPDF
BleachPDF is a free desktop utility for Linux and macOS that redacts sensitive information from PDF files, including scanned pages. It converts each page into an image, applies OCR to locate text you specify, covers matches with black boxes, and writes a new PDF. The resulting file contains images only, so it has no hidden text layer that could reveal redacted wording through copying and pasting. Matching can use exact text or more complex patterns, including case-insensitive rules and digit patterns. Its command line accepts a folder or file pattern for batch processing. After redaction, BleachPDF rescans the output; if matching text is still exposed, verification fails and processing stops. It runs locally without uploading documents. Installation uses pip and requires Tesseract, with OCR language selection such as eng or eng+kor. Handwriting, unusual fonts, poor scans, and tiny dense text can cause recognition errors, so manual checking is advised.
