Batch redaction is the removal of personal data from a whole folder in one run. UK GDPR and the DPA 2018 apply the same handling limits to each item, under ICO oversight. anonym.plus processes up to 20 at a time on your device, with a shared map so one party maps to one alias everywhere.
When this applies
A case folder holds many files that name the same parties. One-by-one work risks drift, so a batch run applies the UK GDPR limits evenly across the set.
How anonym.plus handles it
- Point anonym.plus at the case folder on your machine.
- It scans each item for names, accounts, and IDs.
- Local OCR reads any scanned pages in the set.
- A shared map keeps repeat parties steady across files.
- Review the summary and fix low-confidence flags.
- Save the clean set locally.
What you need to provide
- A folder of files (PDF, DOCX, mixed).
- The shared label map turned on for steady results.
- An operator (Replace works well for a case folder).

Limitations & cautions
A mixed folder of scans and native files leans on OCR for the images, so review low-confidence flags. The shared map can re-link the set if kept; turn it off when you need true anonymity.
Frequently asked questions
How does batch mode keep one party steady?
A shared map logs each person once, so the same party maps to the same alias in every file across the folder.
How many files can one run handle?
Up to 20 documents per batch, all processed locally with OCR for any scanned pages.
Does batch work upload anything?
No. The whole run is offline, so the set stays on your machine.
