C# API to Convert EML to JPEG
- Open EML file using MailMessage class
- Convert EML to HTML by using Save method
- Load HTML by using Document class
- Save the document to JPEG format using Save method and set Jpeg as SaveFormat
Get Started with .NET File Format APIs
Install from command line as nuget install Aspose.Total or via Package Manager Console of Visual Studio with Install-Package Aspose.Total.
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
MailMessage message = MailMessage.Load("sourceFile.eml");
// save EML as a HTML
message.Save("HtmlOutput.html", SaveOptions.DefaultHtml);
// load HTML with an instance of Document
Document document = new Document("HtmlOutput.html");
// call save method while passing SaveFormat.Jpeg
document.Save("output.jpeg", SaveFormat.Jpeg);
Parse EML File via .NET
Before converting EML to JPEG, if you want to make sure that you are converting the correct email, you can load EML document, parse it and have a look at your desired property. By using MapiMessage class of Aspose.Email for .NET API, you can get sender and recipients information. For example, you can check for a specific sender email for the conversion by using SenderName property.
var outlookMessageFile = MapiMessage.FromFile("message.eml");
// check for SenderName
if(outlookMessageFile.SenderName == "John"){
//proceed with conversion process
}
Restrict JPEG Document Editing via .NET
While saving the document from EML to JPEG, you might need to protect your output document. Sometimes you may need to limit the ability to edit a document and only allow certain actions with it. This can be useful to prevent other people from editing sensitive and confidential information in your document. Aspose.Words for .NET API, enables you to control the way you restrict the content using the ProtectionType enumeration parameter. You can set your document to read-only by using the following lines of code.
Document document = new Document("HtmlOutput.html");
// apply document protection and set protection password
doc.Protect(ProtectionType.ReadOnly, "password");
// call save method while passing SaveFormat.Jpeg
document.Save("output.jpeg", SaveFormat.Jpeg);

What is EML File Format?
The EML file format, standing for Electronic Mail, is a widely used file format for storing email messages. It is primarily associated with email clients such as Microsoft Outlook, Mozilla Thunderbird, and Windows Mail. EML files contain the entire contents of an email message, including the sender and recipient information, subject, date, attachments, and the message body.
EML files are formatted in plain text and adhere to the Multipurpose Internet Mail Extensions (MIME) standard, which allows for the inclusion of various types of content within an email message, such as text, images, and attachments. This makes EML files highly versatile and compatible with different email clients and platforms.
The EML format is commonly used for archiving or transferring individual email messages. It provides a convenient way to store emails as separate files, making it easier to organize and retrieve specific messages when needed. EML files can be opened and viewed in compatible email clients, allowing users to read and interact with the contents of the email message.
Furthermore, EML files can be easily shared via email or other file transfer methods. They preserve the original formatting, ensuring that the recipient sees the email exactly as it was sent, including any attachments or embedded images.
In addition to being used for individual email messages, EML files are also used in email migration and backup processes. They allow for the transfer of email messages between different email clients or the creation of backups to safeguard important communications.
What is JPEG File Format?
JPEG, short for Joint Photographic Experts Group, is a widely adopted standard for compressing photographic images. Developed by the International Organization for Standardization (ISO), JPEG employs a lossy compression algorithm to reduce the file size of images. During compression, certain image data is discarded, allowing for smaller file sizes. The extent of data loss can be adjusted, enabling users to balance file size and image quality according to their requirements.
As a highly popular format, JPEG finds extensive usage in storing and sharing photos. It is widely supported by various image editing software and web publishing platforms. Its compatibility makes it easy for users to work with JPEG files across different applications and platforms.
One of the key advantages of JPEG is its ability to significantly reduce file sizes while maintaining acceptable image quality. This makes it ideal for web-based image sharing, where smaller file sizes enable faster uploading and downloading. JPEG compression achieves higher levels of compression by eliminating redundant image information and exploiting the limitations of human visual perception. While this results in a loss of some image details, the trade-off between file size and image quality can be adjusted to suit specific needs.
