Batch redaction is the removal of personal PII from a whole folder of releases in one run. FOIA Exemption 6 lets you withhold data whose disclosure would invade personal privacy. anonym.plus applies the same rule across each file on your device.
When this applies
A large request returns hundreds of files, with the same people across many. One-by-one work risks drift. A batch run keeps the redaction even.
How anonym.plus handles it
- Point anonym.plus at the folder on your machine.
- Local OCR reads any scanned pages first.
- The tool flags personal PII the same way in each file.
- A shared map keeps repeat people steady across the run.
- Review the summary and fix low-confidence flags.
- Save the cleared set on your device.
What you need to provide
- A folder of releases (PDF, DOCX, or mixed, up to 20 at a time).
- The shared label map turned on for steady results.
- An operator: Redact for the public copies.

Limitations & cautions
A batch handles up to 20 files per run, so split a very large request. Mixed folders lean on OCR for scans, so review low-confidence flags. The exemption call is yours; the tool applies your rule but does not judge each withholding.
Frequently asked questions
How does batch mode keep one person steady?
A shared map logs each person once, so the same name maps to the same label in every file across the folder.
How many files can one run handle?
Up to 20 at a time. For a larger request, split it into batches. Each run stays local on your own hardware.
Can the batch mix PDFs and scans?
Yes. Mixed types work. Scanned pages are read with local OCR before the PII check.
