Why convert MBOX to BMP?
MBOX stores a whole mail folder in one file and is used by Thunderbird, Apple Mail exports and Google Takeout. The image shows each message in turn, every one with its own table of From, To, Cc, Subject and Date, followed by its body and any attachment names, beneath an “MBOX email archive” heading.
BMP stores every pixel uncompressed, so the image is exact and simple to read by any software that handles Windows bitmaps.
Frequently Asked Questions
How do I convert MBOX to BMP?
Drop your MBOX file above and press Convert. Our servers split the archive into its messages, lay out each one with its headers and body, and render the pages. The result is saved as an uncompressed BMP bitmap, ready to download.
How are the many emails in an MBOX file arranged in the BMP?
They appear one after another in the order they are stored, each starting with its own header table.
Which programs' MBOX exports can be converted to BMP?
Thunderbird, Apple Mail and Google Takeout all write standard mailboxes where each message begins with a “From ” line, and the converter splits the file on those lines.
What happens when a MBOX file fills several BMP pages?
Each page is rendered at 144 dpi and saved as its own BMP image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one BMP file.
What kind of BMP does the MBOX converter create?
A standard Windows bitmap with every pixel stored uncompressed, so the image is an exact copy of the rendered result.
Is my .mbox file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
