Question 1

What is an EML file?

Accepted Answer

An EML file is a standard email message format used by most email clients including Outlook, Apple Mail, and Thunderbird. It contains the full email including headers, body HTML, plain text, and embedded attachments in MIME format. EML files can be opened, inspected, and converted to HTML for editing.

Question 2

How do I convert an EML file to HTML?

Accepted Answer

The RenderOps EML Converter parses your EML file entirely in the browser, extracts the HTML email body, decodes base64 attachments, and outputs clean HTML ready for editing. No server upload required — your email data stays private on your device.

Question 3

How do I extract the HTML from an email I received?

Accepted Answer

Save the email as an EML file from your email client (File > Save As in Apple Mail or Outlook), then upload it to the EML Converter. It extracts the HTML body, inline images, and plain text version separately so you can analyze or edit each component.

Question 4

Can I convert HTML back to EML?

Accepted Answer

Yes — the EML Converter also works in reverse. Paste or upload an HTML file and it wraps it in a proper MIME-formatted EML structure with the correct headers, allowing you to open the result in any email client for testing.
