Whether you need to combine emails from a project, a client conversation, or a specific time period, our Merge Emails to PDF tool lets you combine multiple .eml files into one well-structured PDF document.

Why Merge Emails to PDF?

Individual .eml files are useful for single messages, but combining them offers several advantages:

• Single document – One PDF instead of dozens of separate .eml files to manage.
• Chronological order – Emails appear in the PDF in the exact order you upload them, making it easy to create timelines.
• Universal compatibility – PDFs open on any device without needing an email client.
• Legal and compliance – A single merged PDF is easier to submit as evidence or for regulatory review.
• Searchable – Search across all merged emails at once in any PDF viewer.
• Print-ready – Print the entire conversation as one document.

What Is an .eml File?

An .eml file is a standard format for storing a single email message. It follows the RFC 5322 / MIME standard and contains the complete email: headers, the message body, and any attachments encoded in base64.

Almost every email client can export messages as .eml files:

• Gmail: Open the email → Three-dot menu → “Download message”
• Outlook: Save the message or drag it to a folder as .eml
• Apple Mail: Select the message and choose “Save As”
• Thunderbird: Right-click the message and choose “Save As”
• Yahoo Mail: Open the message and choose “Download message”

How to Save Emails as .eml Files

The exact steps vary by client, but the general pattern is simple:

1. Open the email you want to save.
2. Look for “Download”, “Save As”, “Export”, or “More options”.
3. Choose .eml or “Raw Message” format.
4. Save the file to your computer.
5. Repeat for each email you want to merge.
6. Upload all .eml files to our merger.

What Gets Preserved in the PDF

For each email in the merge, the converter extracts and preserves the sender, recipients, subject, date, full text body, and a list of attachment names. Each email becomes a distinct section in the PDF, separated by a visual divider. Sections appear in the exact order the files were uploaded.

Upload Order and Organization

The merge order follows your upload order exactly. To create a chronological timeline, sort your .eml files before selecting them, upload them in that sequence, and review the file list before merging. You can add more files or rearrange them in the upload area.

Attachments Handling

Email attachments are listed by filename and type in each email’s section. The attachment files themselves are not extracted or embedded in the PDF, keeping the output focused on message content and avoiding potential security risks from executable attachments. Save attachments separately from your email client when you need the original files.

Privacy and Security

Emails often contain sensitive information. Files are processed temporarily, require no account, and are automatically deleted after the processing window. Uploads and downloads use HTTPS. For highly sensitive emails, an offline solution may be preferable, but the online merger is convenient for ordinary archiving and sharing.

Frequently Asked Questions

How many emails can I merge at once?

You can upload multiple .eml files up to the tool’s configured upload limit. For very large collections, merge in batches and combine the resulting PDFs with our Merge PDF tool.

Does the merge preserve the original email order?

Yes, emails appear in the PDF in the exact order they were uploaded. Review and reorder the files before merging if needed.

Can I merge .msg files from Outlook?

The tool accepts standard email files supported by the upload control. If an Outlook .msg file is rejected, open it in Outlook and save it as .eml first.

Are email attachments included in the merged PDF?

Attachments are listed by name and file type, but their binary contents are not embedded in the PDF.

Is there a file size limit?

Yes. The upload control and server enforce a file-size limit. Individual email files are typically small, so many messages can usually be merged in one operation.

Does the merger preserve HTML formatting from emails?

The converter prefers the plain-text body. If only HTML is available, it strips markup and renders the readable text in the PDF.

Can I merge emails from different email clients?

Yes. Standard .eml messages can be merged regardless of whether they came from Gmail, Outlook, Apple Mail, Thunderbird, or another client.

Is my email content stored on your servers?

No. Files are processed temporarily and automatically deleted after the brief processing window.
