Convert EML email files to standalone HTML pages. The converter creates a self‑contained HTML file that keeps the Outlook‑style header block and embeds every inline image, so the page looks the same offline. Only the email body and its inline images are included; binary attachments such as PDFs are omitted.

Outlook‑style header block

The converter extracts the standard header fields—From, To, Cc, Subject and Date—from the .eml file and reproduces them in an Outlook‑style header block placed above the message body in the HTML output. Each field appears as a label/value pair in the original order. The Bcc field is omitted to match Outlook’s typical display.

Body formatting and character encoding

If the source email contains an HTML body, the tool copies the complete markup, including embedded CSS, inline styles and structural elements, so the visual layout stays identical in the browser. For plain‑text‑only messages, the text is wrapped in a simple block that preserves line breaks without adding styling. The declared character encoding of the email is respected, allowing Cyrillic, Arabic, CJK and other non‑Latin scripts to render correctly when the appropriate fonts are available.

Embedded inline images

Images that are embedded as MIME parts in the .eml are converted to data‑URI sources and inserted into the image tags of the output HTML, making the file completely self‑contained. This ensures that the pictures appear offline exactly as they did in the original email. Images referenced only by external URLs are left as normal URLs, so the browser will load them when the page is viewed.

Hyperlinks and external resources

All hyperlinks—including standard http/https URLs and mailto: addresses—are copied verbatim into the HTML and remain clickable in any modern browser. External image references are also preserved as ordinary URLs, allowing the browser to retrieve them at view time; a missing remote host results only in a broken image placeholder, not in a failure of the document.

Limits and scope

File‑size limits: Conversion respects the tier‑specific upload caps; anonymous users have a lower maximum size than signed‑in users, with higher subscription tiers allowing larger files.
Download retention: Generated HTML (or ZIP) download links remain active for 24 hours after conversion completes.

FAQ

Are hyperlinks clickable in the generated HTML?

Yes, all hyperlinks — including http, https, and mailto links — are copied unchanged into the HTML and remain clickable in any modern web browser.

How are embedded inline images handled in the output HTML?

Images embedded as MIME parts in the original EML are converted to data‑URI sources and inserted directly into the HTML, making the file completely self‑contained and viewable offline.

What happens to the Bcc field when converting an EML to HTML?

The Bcc header is omitted from the Outlook‑style header block in the generated HTML, so it does not appear in the output even if it was present in the source email.

What are the file‑size and batch limits for converting EML files?

The maximum size of a single EML file or the total size of a batch depends on your account tier – anonymous users can upload only small files, a free Aspose account raises the limit, and paid tiers allow progressively larger uploads.

How long is the converted file available for download?

The generated HTML (or ZIP) download link remains active for 24 hours after the conversion finishes, after which it expires.
