Why convert S/MIME to GIF?
S/MIME files hold an email secured with a digital signature or certificate, as sent by Outlook, Apple Mail and other clients that use S/MIME. The image shows the From, To, Cc, Subject and Date of the message, its body, and a list of attached parts by name and type.
GIF stores the image with an optimised palette of up to 256 colours, which suits text, diagrams and flat colour.

Frequently Asked Questions
How do I convert S/MIME to GIF?
Drop your S/MIME file above and press Convert. Our servers read the signed message, lay out its headers and body, and render the page. The result is saved as a GIF image, ready to download.
Can a signed S/MIME email be converted to GIF without the sender's certificate?
Yes. The message is read as it was received, so its headers and body are laid out with no certificate or key needed.
Are the Cc recipients of an S/MIME email included in the GIF?
Yes. When the message was copied to others, a Cc row lists them beneath the From and To rows in the header table.
What happens when a S/MIME file fills several GIF pages?
Each page is rendered at 144 dpi and saved as its own GIF image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one GIF file.
How are colours handled in the S/MIME to GIF image?
GIF uses a palette of up to 256 colours. The converter builds an optimised palette from the rendered image, which keeps text, lines and solid colours clean.
Is my .smime 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.
