Why convert MIME to ICO?
A MIME file holds an internet email in the standard Multipurpose Internet Mail Extensions format, with headers, body parts and attachments. The image shows the message headers (From, To, Cc, Subject and Date), the decoded body with its formatting, and a list of attached parts by name and type.
ICO output is a 256 × 256 pixel Windows icon: the image is scaled to fit with its proportions kept, and the surrounding space is transparent.
Frequently Asked Questions
How do I convert MIME to ICO?
Drop your MIME file above and press Convert. Our servers decode the MIME parts, lay out the headers and body, and render the page. The result is saved as a 256 × 256 ICO icon, ready to download.
Is the encoded body of a MIME message readable in the ICO?
Yes. Base64 and quoted-printable parts are decoded before layout, so the ICO shows the actual words and formatting of the message.
Which part of a multipart MIME message appears in the ICO?
When the message has an HTML part, that version is rendered with its formatting. A message written in plain text is shown as neatly wrapped text.
Which part of the MIME becomes the ICO icon?
The first page of the rendered content is used for the icon, fitted inside the 256 × 256 square with its proportions kept.
What size is the ICO made from a MIME file?
The icon is 256 × 256 pixels, the largest standard Windows icon size. The image is fitted inside the square with its proportions kept and a transparent surround, stored as a PNG-compressed icon.
Is my .mime 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.
