Local EML email inspector

What it does

Open saved email locally, inspect headers and plain text, and download selected attachments.

How to use it

1. Choose a saved .eml file, inspect it and download the structured report or individual attachments.
2. Processing stays in your browser. No upload or sign-up.

Example

A multipart email shows its Subject and plain-text body alongside a downloadable PDF attachment.

Methodology

Bundled postal-mime decodes MIME parts in a terminable worker. HTML is omitted; headers are shown as unverified text and attachment downloads retain original bytes.

Limitations

10 MiB input and decoded attachment budget, 500 headers, 50 attachments, one million body characters, MIME depth 20 and a 15-second worker deadline. No mailbox connection, sending, remote images, attachment execution or authenticity verdict.

Automation

This tool runs in your browser. No upload API or MCP endpoint is available.
