How to use File Metadata Privacy Scanner

  1. Select Documents and media using the file area.
  2. Review the selected filenames and sizes.
  3. Choose any available options and click Scan Privacy Signals.
  4. Read the findings, then download the JSON privacy signal report.

What this file tool does

Checks file-system metadata, filename patterns, common image metadata markers, and readable text samples for email addresses, phone-like numbers, GPS labels, and author fields.

The scanner reads at most the first 2 MiB of each file, searches conservatively for recognizable privacy indicators, and creates a JSON report.

Your selected files stay in this browser session. Binary formats can hide metadata in structures this browser-only scanner does not fully parse. A clean report is not proof that all private data is absent.

Frequently asked questions

How can I use file metadata privacy scanner without uploading files?

Choose the requested files in this page and run the tool. Processing happens in your browser, and only the result you download leaves the page.

What does the downloadable json privacy signal report contain?

It contains the actual result or evidence produced from the selected file bytes and metadata, with the important findings shown on screen as well.

Can I use file metadata privacy scanner on a large file?

Browser memory and device speed set the practical limit. Start with a smaller sample if the file is several gigabytes or the device has limited memory.

Does this tool change my original files?

No. Browser file access is read-only here. The tool creates a separate result for download and does not overwrite the selected originals.

Is a clean result a complete security guarantee?

No. The result covers the checks described on this page. Use specialized desktop or forensic software when you need deeper validation.
