Complete Guide to Convert EML to EMLX on Windows and Mac
User Query: “I have a lot of EML files saved from my old Windows Mail account. But now I use Apple Mail. How can I change EML files into EMLX without any hassle to open my old emails in Apple Mail?”
One of the biggest problems people run into after moving from Windows to Mac is old email files. Windows email apps save messages as EML, but Apple Mail only works with EMLX. Because of that, emails don’t open properly after the switch. In this blog, I’ll share a couple of simple ways to convert EML to EMLX. One method is manual, and the other is quicker and more secure by using the MailConverterTools EML Converter Tool, if you just want things done without losing any data.
Why Do Users Change EML to EMLX?
- Apple Mail doesn’t open EML files properly, so users need EMLX instead.
- Most people switch formats after moving from a Windows PC to a Mac.
- Old EML emails may not show correctly in Apple Mail.
- EMLX files are easier to manage inside Apple Mail folders.
- Importing emails works more smoothly when they’re already in EMLX format.
- Users want all their old emails in one place without missing anything.
- Converting avoids repeated errors while opening EML files.

How to Convert EML to EMLX Using the Manual Method?
You could skip third-party apps and do it yourself, but this only works for simple EML messages. It also takes time and isn’t ideal if you have a large number of emails.
Steps to Export EML to EMLX
- First, open Apple Mail on your Mac.
- Next, drag and drop the EML files into any mailbox or folder inside Apple Mail.
- Once the files are added, Apple Mail automatically changes them into EMLX format in the background.
- After that, this EML to EMLX conversion helps you to open and manage those emails normally within Apple Mail.
Limitations
- There’s no option to convert files in bulk properly.
- Folder structure is not always maintained.
- Large EML files may not import correctly.
- If Apple Mail crashes, you may need to start again.
- No clear confirmation that all emails were converted.
- Not practical for users with years of old emails.
