HTML documents take very little space while stored on a computer’s hard drive or an external drive.
There is no internet connectivity required to read HTML files locally.
All web browsers are compatible to open HTML documents without facing any hassle.

How to Convert MSG to HTML Format? Direct Answer

You can convert your MSG files into HTML using two ways: first, the manual method via renaming the files using the MS Outlook one by one, or directly use the automated MSG to HTML converter for bulk conversion. The manual method is recommended when you have just a few files to export, whereas when you have a large number of MSG files in large size, choose the dedicated solution. Let’s discuss both ways briefly below.

Manual Way to Convert MSG to HTML File Format

Users can also change MSG file to HTML format using MS Outlook Personal Information Manager (PIM) with some limitations.

Go to the location where MSG files are stored on your computer.
Select an MSG file and open it with the MS Outlook client.
Thereafter, your MSG file will be opened using the Outlook interface.
Now, choose File >> Save As option.
Choose the HTML File option from the drop-down.
Browse to the location to store the HTML file and press the Save button.
Repeat the above-mentioned steps again to change another MSG file to HTML.

Limitations of the Manual Method

This method is not scalable as it takes a lot of time to convert MSG to HTML. You have to export each MSG file one by one, as there is no bulk conversion available.
Files having crucial information, complex HTML formatting, and embedded media may lose the information or data elements while converting manually.
This method is fully dependent on Outlook. If you want to export your MSG files using Outlook, you should have a subscription; you can’t convert your MSG files.
Manually converting MSG files does not include all the important attributes. Attachments, fonts, images, hyperlinks, metadata, and other information oftwen gets lost while manually exporting MSG into HTML.
It is not a secure option as this method does not guarantee to keep the original data, hierarchy, and data structure the same as before.

Alternative Solution to Convert MSG to HTML File Format

If you don’t want to use the manual method, the best way to overcome all the limitations of the manual method is by using the professional MSG to HTML converter tool. To convert large MSG files into HTML without data loss, corruption, or consuming time, use the smart MSG converter for smooth and secure conversion.

Whereas manual methods are not advisable for users, as it is a risky process and not meant for individuals without crucial or large-sized MSG files. And, the smartest way to convert MSG files is to use the dedicated software instead of buying the Outlook subscription, and still not be able to convert securely in bulk. You can try the free demo version, which allows users to freely use and test the tool.
