Add Your Files or Text
Everything happens on this computer — files are read in this tab and never uploaded. Add what you want to anonymize; you'll review what was found on the next screen.

PDF · Word (.docx) · Excel (.xlsx) · PowerPoint (.pptx) · OpenDocument · RTF · and any plain-text format (.txt, .md, .csv, .json, .html…).
Office and PDF files have their text extracted right here in this tab — nothing is uploaded anywhere. Scanned PDFs (no text layer) and legacy .doc/.xls/.ppt are flagged with what to do instead.

Anonymized Output & Export
Each file gets an anonymized copy, plus a log that converts everything back in the Restore step. Keep the log private — it maps labels to real names.

Everything happens in this tab — the page makes no network requests and works offline.
Files are read directly by your browser and never leave this computer; anonymized copies are
saved only where you choose (folder, .zip, or download). The only thing stored is your key
(labels and names, never your documents), kept locally in this browser so a reload doesn't
lose it. “Wipe local data” erases all of it.
