## Frequently asked questions

### What is an EML file?

EML (.eml) is a plain-text file format for storing a single email message, following the RFC 822 / RFC 5322 standard. It contains email headers (From, To, Subject, Date), the message body (plain text and/or HTML) and optional attachments encoded in Base64.

### Are my EML files uploaded?

No. Emails you open from your device stay on your device and are parsed locally. Only the public sample email is requested from the server.

### Can it open attachments?

The viewer lists attachments and their metadata. Downloading or opening attachments depends on browser capabilities and the attachment type.
