BleachPDF vs PII Tools

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.

PII Tools locates and helps remediate personally identifiable information, payment-card data and health information across digital assets. It scans more than 400 file formats in local or cloud storage, covering structured and unstructured data. Analytics and reporting support review, while users can redact or erase information individually or in batches. Person Cards aggregate detected records associated with people across files, email and databases, with spreadsheet export. Document redaction supports in-place changes and pseudonymization for PDFs, Excel files and images, and a REST API can automate workflows. Named connectors include Microsoft 365 Exchange, SharePoint, OneDrive, Salesforce, Google Drive, Amazon S3, Azure Blob Storage, SQL Server, Oracle, PostgreSQL and MySQL/MariaDB. It can run on a customer server, keeping sensitive data within the network according to the maker. Deployment uses Docker-capable machines or virtual machines. A seven-day hosted trial is available by contacting PII Tools.
