How to convert EML to ZIP

  1. Add your EML emails

    Drop EML files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. ZIP is already chosen

    Press Convert. There is nothing else to set. The work happens in this tab.

  3. Download

    Save the ZIP, or download everything as one ZIP if you converted several files.

Why ToAny

  • Private by construction

    The EML to ZIP converter is part of this page and runs inside your browser. Your emails are never sent to ToAny or to anyone else.

  • No upload, no queue

    Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

EML to ZIP: what to expect

To get the attachments out of an EML without a mail program, they have to be decoded from the text the message stores them in. A ZIP of the message and its attachments is easy to store, email or archive.

The ZIP holds the message as a page and as text, and an attachments folder with every attachment. Attachment names come from the sender, so folders, control characters and duplicates in them are cleaned up. Headers in other character sets (UTF-8, ISO-8859, ISO-2022-JP and the like) and encoded bodies and attachments are decoded. Messages up to 100 MB are accepted.

EML vs ZIP

EML

E-mail message

An EML file is one email saved as plain text: headers such as From and Subject, then the body, with attachments encoded as text. The layout is the Internet message format that mail servers use. Most mail programs can open it and drag-and-drop one out of a message list.

Opens in Outlook, Apple Mail, Thunderbird and any text editor

ZIP

ZIP archive

ZIP bundles files and folders into one compressed file. Every operating system can open it without installing anything, which makes it the safe choice for sharing.

Opens in Windows, macOS, Linux, iOS and Android without extra software

Questions

Are my emails uploaded anywhere?

No. The EML to ZIP conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Is anything lost when converting EML to ZIP?

The content is carried over as faithfully as ZIP allows; features that ZIP does not have are left out.

Can I convert several EML files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert EML to ZIP on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the EML file, press Convert and save the ZIP. There is nothing to install.

Is there a file size limit?

Yes. A message can be up to 100 MB; a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
