What makes Aid4Mail the best EML to PDF converter?
Accurate conversion
Aid4Mail is known for its faithful conversions. Embedded media and attachments are included and placed in the correct location. This is not the case for some of our competitors, as demonstrated in the PDF documents below. They show the difference in output between Aid4Mail and SysTools EML to PDF Converter.
Note that Aid4Mail converts not only the content of an email message but also its metadata, including messages status flags: Unread, Read, Replied, etc. This information is usually overlooked by other email conversion products but can be crucial in an investigation, or for maintaining archives for legal compliance.
Security through on-premises conversion
Online converters may be convenient, and even free, but are they secure? You’re uploading your sensitive emails to another company’s website. You don’t know who they are, where their servers are located and, more importantly, what they are doing with your data!
In addition, many countries now have strict regulations about what you can do with customer data. You may be breaking the law simply by uploading a document to an online EML to PDF converter.
Aid4Mail is installed software and your valuable data never leaves your computer. All processing is done locally, on-premises, and nothing is sent to our servers. Our income comes from selling our software, not from selling your data!
Bulk convert EML to PDF
Usually you don’t want to convert just one email. Typically, it’s a group of emails, perhaps one or more folders, or your whole email archive.
Like other converters, Aid4Mail can convert multiple EML files to PDF as a single batch. But Aid4Mail takes it a step further, enabling you to set up multiple batches. For example, convert 1,000 batches of EML files, one for every employee in a work force of 1,000 people.
Unattended conversion
With Aid4Mail Investigator and Aid4Mail Enterprise, you can launch all those batches together at the same time. Then leave Aid4Mail to process, unattended, while you’re working on something else, overnight or during the weekend. Aid4Mail will queue them and run each one in turn. You don’t have to be present—a huge time saver!
Concurrent processing
Aid4Mail Investigator and Aid4Mail Enterprise also include smart concurrent processing. This enables multiple email batches to be processed at the same time, depending on the resources of your computer. You can set the optimal number for your system, speeding things up even further.
Complete automation
Aid4Mail Enterprise gives you access to the console version of the software. It can be run by a script or another program, allowing you to completely automate your EML to PDF conversions.
Unlike other products, Aid4Mail’s console contains all features because it uses the same high-end conversion engine as the regular Aid4Mail. Everything you can do in Aid4Mail can also be automated in the console.

Aid4Mail’s PDF configuration options
Decide exactly how your PDF documents appear:
Save emails as individual PDFs or merge them into a single document. If you set up multiple batch conversions, you can even create a multi-email document for each batch. For example, a PDF document for each employee containing only their mail.
Create meaningful filenames using email metadata, Bates numbering and custom text. This helps enormously in finding and presenting data.
Email metadata can include useful header fields like the sender name or address, and the message date. For example, the filename template:
Case {CaseID} – {SenderName} – {FolderName} – {BatesNumber}.pdf
might produce a filename like:
Case 01783 – John Doe – Inbox – FS1528374683299.pdf
Specify whether the document is a regular PDF, with all features available, or an archivable PDF/A or press-ready PDF/X.
Encrypt your PDF documents and specify passwords to open the document and control its permissions.
Specify whether a document can be copied, printed and edited, or any combination of these.
Set the document’s title, author, subject and keywords. This information is optional but useful, especially the title, as search engines like Windows Search may use it in their results. Usually when there’s no document title, search engines display the filename instead which is not ideal.
Include custom text, email attributes, page numbering and even Bates stamps in your page headers and footers. Place them on the left or right of the document, or both. You can even specify the size of the margin that contains them.
Decide exactly how much of the email header to include in the PDF and where to place it. For example, specify a short header at the beginning of the document, with only essential fields like the sender, recipients, subject and date, and append the full email header at the end.
PDF document content can also be customized using Python scripts. For example, use a Python optical-recognition library to grab the text from an image attached to the email, and append it to the message text. This requires programming knowledge but is a very powerful tool.
Embed attachments directly into the PDF, or extract them and link to them from the document. Embedding attachments is useful if the PDF is to be shared because it’s completely self-contained. However, it has the potential to be large in size.
Linking to attachments keeps the file size small but fragments the email’s original components. If sent to a third party, you need to remember to send all the attachments along with the PDF.
Determine exactly how your PDF document will look by editing Aid4Mail’s template and CSS style sheets. Change the layout, font, colors and more…

Aid4Mail’s email conversion options
Aid4Mail is packed full of useful features to help you convert EML files to PDF:
Maintain the original email folder structure or choose to flatten it. Alternatively, customize it based on criteria like the sender or recipient’s email address, date, subject or keywords in the text. (This only applies if you are creating one PDF document per email.)
When creating multi-email PDFs, the folder structure is flat by nature so the original hierarchy is lost. But Aid4Mail can save the email’s location in the original folder structure, as metadata, and display it in the PDF. This is particularly useful for documents destined for legal proceedings.
Aid4Mail automatically transfers email metadata from the source mail to the appropriate place in the target format. But what happens when a target format, like PDF, doesn’t have fields for this data? Aid4Mail can add it to ’X’ prefixed fields in the email header to prevent it from being lost. These fields can then be included in the PDF document.
Remove the envelopes from journaled emails. Envelope metadata can even be added back into the email header and displayed in the PDF.
Aid4Mail’s incremental processing enables you to convert your mail to PDF in stages, only processing what wasn’t done previously.
Determine exactly which emails to convert to PDF. In Aid4Mail Investigator and Aid4Mail Enterprise, filter individual emails, whole folders and even attachments by date, subject and keywords.
Avoid duplicates, circulars and unpurged mail. You can even create sophisticated search scripts that target specific email fields and use Boolean operators, proximity functions, wildcards and more.
For cloud accounts like Gmail, Outlook and IMAP, you can filter natively at the server level, saving bandwidth by avoiding unnecessary downloads.
In Aid4Mail Converter, filtering is limited to email folders.
With support for Python scripts in Aid4Mail Investigator and Aid4Mail Enterprise, you can write your own filters, create custom output and even modify the content of converted emails. Create your own features—for example, integrate OCR into your search or scan images for nudity.
Which Aid4Mail edition is right for you?
If you only need to convert one batch of EML files to PDF, then the affordable two-week Aid4Mail Converter license is perfect. If you need to convert files regularly, a one-year renewable license is more economical.
For digital forensics, Aid4Mail Investigator is the right choice. It can collect mail from a large number of mailbox formats and email service-providers and offers powerful filters to remove unwanted emails and duplicates.
To automate your email conversions, save to archival formats like PST, or have multiple employees use Aid4Mail, you need Aid4Mail Enterprise. It does everything the other editions can and more.
All Aid4Mail licenses allow you to convert an unlimited number of mail accounts and files, whether in-house or external.
