Drop MBOX (MBX) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the result. When one file produces several EML files they come as a single ZIP.
The MBOX to EML converter is part of this page and runs inside your browser. Your mailboxes are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
An MBOX is a whole mailbox in one long file, which is how Thunderbird stores folders and how Google Takeout exports Gmail. EML is one message per file, which most mail programs open by double-click and which suits archiving or importing single messages.
One MBOX can produce several EML files (one file per message); when it does, they are offered together as a ZIP download.
Every message becomes its own .eml file, kept exactly as it was in the mailbox, and the files come as a ZIP. Mailboxes up to 400 MB are accepted.
An MBOX file holds many emails one after another in a single text file, each starting with a From line. It is the oldest Unix mailbox layout, Thunderbird stores folders this way, and Google Takeout exports Gmail as MBOX. Several slightly different variants exist.

MBOX converterAn EML file is one email saved as plain text: headers such as From and Subject, then the body, with attachments encoded as text. The layout is the Internet message format that mail servers use. Most mail programs can open it and drag-and-drop one out of a message list.

No. The MBOX to EML conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
Text is kept. Formatting carries over only as far as EML supports it.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the MBOX file, press Convert and save the EML. There is nothing to install.
Yes. A mailbox can be up to 400 MB; a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
