**Legal** Ensure data is truly gone before sharing legal docs.

Overview

This tool is designed for fast, local processing with no server upload. It focuses on clarity and repeatable results.

When to use it

  • When you need a quick result without installing software.
  • When you must keep files on your device for privacy.
  • When you want a predictable output for reuse or sharing.

How it works

Your file is processed in the browser. The workflow is deterministic and optimized for common document patterns.

Best practices

  • Start with a small sample to confirm output expectations.
  • Keep file names simple to avoid OS-specific edge cases.
  • If results look off, try the tool again after a page refresh.

Common mistakes

  • Uploading encrypted or corrupted files without preparing them first.
  • Assuming a tool will fix formatting issues outside its scope.
  • Closing the tab before the download completes.

⚠️ Limits
