Why Choose Expert Solution over the Manual Way? Clear Comparison

Data Integrity & Accuracy
This smart utility guarantees to keep your data structure, file formatting, metadata, and properties intact. It preserves all the important elements of data files like images, hyperlinks, attachments, etc. In contrast, the manual method does not guarantee the preservation of the original data. Some details get lost, or appear broken. If we compare the manual way, it is not ideal and not suggested to convert EML to HTML for professional or personal use, as it can change, damage, or lose your data.
Time & Productivity
As we know, the manual method is time-consuming. It is not recommended to use it if you have multiple EML files to convert, because if you start converting hundreds or thousands of EML files one by one, it can create a lot of chaos and consume time. And if we look at the automated software, it allows you to convert files in bulk, which saves time and increases productivity.
Data Security
The expert tool gives 100% data security as it does not save the data in its environment, and instead of transferring original files, it forwards a copy of the data files to convert data. It guarantees that there will be no data loss or corruption while exporting large files. On the other hand, the manual method has no data security, and it is a risky process. It often corrupts the large files while exporting or dragging & dropping, which may lead to permanent data loss.
