Batch redaction is the removal of personal data from a whole folder of investigation documents in one run. It applies GDPR Recital 26 anonymisation the same way to each one. anonym.plus works on your device, with a shared map so one person maps to one alias.
When this applies
A case archive holds hundreds of documents with the same people across many. One-by-one work risks drift. A batch run keeps the labels even across the whole set.
How anonym.plus handles it
- Point anonym.plus at the folder on your device.
- It scans each document for names, contacts, and IDs.
- A shared map keeps repeat people steady across the run.
- Review the summary and fix low-confidence flags.
- Save the clean archive on your device.
What you need to provide
- A folder of documents (PDF, DOCX, or mixed).
- The shared label map turned on for steady results.
- An operator (Replace works well for an archive).

Limitations & cautions
Mixed folders (some scanned, some native) lean on OCR for image scans, so review low-confidence flags from them. A shared map keeps results even, but you must guard that map, since it can re-link the set if kept.
Frequently asked questions
How does batch mode keep one person steady?
A shared map logs each person once, so the same subject or witness maps to the same alias in every document across the folder.
Can the batch mix PDFs, DOCX, and scans?
Yes. Mixed types work. Scanned pages are read with local OCR before the check. The batch size is up to 20 documents per run.
Is there a cloud quota on size?
No. Work is local, so speed depends on your hardware, not a cloud plan.
