How it works
Your email never leaves your device
01
Drop the file
Drag in any .eml file — from Gmail's “Download message”, Apple Mail, Thunderbird, or an email backup.
02
Parsed in your browser
JavaScript decodes the MIME structure locally. No upload, no server, no copy of your email anywhere.
03
Read everything
The rendered message, the plain-text version, every header, the raw source, and downloadable attachments.
What's a .eml file?
A .eml file is one email message saved in the internet's standard format (RFC 822/5322) — headers, body, and attachments in a single portable file. It's what mail servers actually exchange, which makes it the most faithful way to keep an email. Read the full guide: What is a .EML file?
FAQ
Is it safe to open my email here? Is anything uploaded?
Nothing is uploaded. The file is parsed by JavaScript running locally in your browser — it never touches our servers. You can load this page, disconnect from the internet, and the viewer still works.
Why don't images in the email load?
Remote images are blocked by default because senders use them as tracking pixels — loading them reveals that (and when) the message was opened. Use the “Load remote images” toggle to display them. Images embedded inside the file always display.
Which files can I open with this viewer?
.eml files — the standard RFC 822/5322 email format. That's what you get from Gmail's “Download message”, dragging a message out of Apple Mail or Thunderbird, or saving from Outlook as .eml. Outlook's proprietary .msg format is a different, binary format and won't open here.
Can I see and download attachments?
Yes. Attachments are decoded from the file and listed with their name, type, and size. Downloads happen locally in your browser, straight from the parsed file.
How do I save emails as .eml files in the first place?
In Gmail, open a message and choose “Download message” from the ⋮ menu. In Apple Mail or Thunderbird, drag the message to a folder. To archive every email automatically, InboxBucket saves incoming mail as .eml files to your own Google Drive, OneDrive, Dropbox, or S3.
