Slop EML · free, in your browser
Convert an MBOX mailbox to PDF
A mailbox export holds many emails in one .mbox file. Slop EML splits it into messages you can read, search, tick and save as PDF.

How to do it
- Drop the .mbox file on the page. Each email in it appears in the list.
- Search by sender, subject or attachment name, and tick the messages you need.
- Choose Combine into one PDF, or Export for one PDF per message, plain text, HTML, Markdown or the original .eml files.
- Export the list as CSV for a spreadsheet of dates, senders and subjects.
Your files stay on this device: Slop EML runs in your browser, with no upload, no account and no watermark.
Questions
Where do I get an .mbox file?
Google Takeout exports Gmail as .mbox. Thunderbird keeps each folder as an mbox file, and Apple Mail can export a mailbox.
How big can the mailbox be?
It is read in your browser, so it depends on your device's memory. Mailboxes of a few hundred megabytes are fine on a computer.
Are attachments kept?
Yes. Save all attachments puts them in a ZIP with one folder per message.
