Click inside the file drop area to upload your files or drag & drop them.

This tool converts one or more .eml email files into reflowable .epub e‑books that open in any standard EPUB reader. It preserves the email headers and carries over the original HTML formatting, embedding all inline images directly into the e‑book. The converter handles only the message content; attached files or calendar invites are excluded.

Email headers preserved

All standard headers – From, To, Cc, Subject, and Date – are copied verbatim to the top of the generated EPUB, appearing as the first block above the message body. Hidden fields such as Bcc are omitted, matching typical email‑client display.

Rich body formatting and searchable text

The converter translates the email’s HTML body into EPUB‑compatible markup, preserving paragraph breaks, headings, ordered and unordered lists, bold, italic, underline, and table structures. Plain‑text‑only messages become a single searchable, selectable block of text.

Embedded and external images

Images embedded directly in the .eml are extracted and packaged inside the EPUB, making the e‑book self‑contained. For images referenced by external HTTP/HTTPS URLs, the service attempts to download each one, allowing up to two seconds per image and a total of ten seconds; images that exceed this limit are omitted without placeholders.

Clickable hyperlinks

Web links and mailto: addresses from the original email remain active in the EPUB. The visible anchor text and its target are preserved, so readers can tap or click the link to open a browser or compose a new email, provided the reading app supports link navigation.

Attachments and calendar invites excluded

Binary attachments such as PDFs, ZIP files, or separate image files are not carried into the EPUB; the conversion focuses on the email’s textual and inline visual content. Calendar invitations are treated similarly, appearing only as plain text if present.

FAQ

Are email headers included in the generated EPUB?

Yes – the From, To, Cc, Subject and Date headers are copied verbatim and placed as the first block above the message body; Bcc fields are omitted.

Are hyperlinks from the original email still clickable in the EPUB?

Web links and mailto: addresses are preserved and remain clickable in EPUB readers that support link navigation, with both the visible text and target URL unchanged.

How are inline and external images handled in the EPUB?

Embedded images are extracted and stored inside the EPUB. External images are downloaded (max 2 s each, 10 s total); those that load in time are included, others are omitted without placeholders.

What is the maximum number of .eml files I can convert in one batch?

You can upload up to 10 .eml files at once; the service processes them in parallel and returns a single ZIP archive containing the resulting EPUB files.

How long are the converted files available for download?

The generated EPUB (or ZIP of EPUBs) can be downloaded for 24 hours after conversion; after that the download link expires.
