MSG to PDF API Overview
The MSG to PDF API converts MSG email files into PDF.
This API allows you to customize various aspects, such as email headers, page orientation, page size, and margins. It also provides options for compressing files, converting email attachments, and merging them with the email body to create PDF and PDF/A-compliant documents.
This API is especially valuable for businesses needing to maintain an accessible and standardized email archive and for legal firms that require secure, tamper-proof email documentation for evidentiary purposes.

File
File Supported formats: .eml .msgFile to be converted. Value can be URL or file content.
ConvertHeader
Bool Default: TrueThis property controls the inclusion of email header in the PDF conversion process.
When set to true, the converter will incorporate the email's header information, such as From, To, Subject, Date, etc., into the generated PDF file.
When TemplateFile is set, this parameter has no effect - the template decides which header fields appear.
TemplateFile
File Supported formats: .html .htmCustom HTML page used to lay out the converted email. Value can be URL or file content. When not set, the built-in template is used (with or without the header table depending on ConvertHeader). When set, ConvertHeader has no effect - the template decides which header fields appear.
The template is plain HTML with the following placeholders:
{{subject}}- email subject{{from}}- sender{{to}}- recipients{{cc}}- copied recipients{{sent}}- sent date, formatted according toDateTimeFormat{{emailContent}}- the email body, inserted where the placeholder is
Example:
<html>
<body>
<h2>{{subject}}</h2>
<p>From: {{from}} - Sent: {{sent}}</p>
{{emailContent}}
</body>
</html>The email body is rendered in its own isolated block, so the email's CSS does not affect your page and your CSS does not affect the email.
DateTimeFormat
StringFormat of the Sent date shown in the email header, as a .NET custom date and time format string. When not set, the date is printed in US style with a 12-hour clock. Common values:
yyyy-MM-dd HH:mm- ISO order, 24-hour timeyyyy/MM/dd HH:mm- year first with slashesdd.MM.yyyy HH:mm- day first with dotsdd-MM-yyyy HH:mm- day first with dashesdd/MM/yyyy HH:mm- day first with slashesMM/dd/yyyy h:mm tt- month first, 12-hour clock with AM/PMyyyy-MM-dd- date onlyyyyy-MM-dd HH:mm zzz- with the sender's UTC offset
Supported format specifiers: yyyy year, MM month number, MMM abbreviated month name, MMMM full month name, dd day, HH hours (24-hour clock), hh hours (12-hour clock), tt AM/PM designator, mm minutes, ss seconds, zzz UTC offset. Other characters are printed literally. Literal words must be enclosed in single quotes, for example d MMMM yyyy 'at' HH:mm. Month and day names are rendered in English.

IgnoreAttachmentErrors
Bool Default: FalseWhen enabled, attachment conversion errors are ignored and the email is still converted. This parameter is only used when ConvertAttachments is enabled.

StoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
