Convert images

Not all mail clients can display SVG images in mails. Gmail, for example, does not support displaying SVG images. This results in Confluence pages with SVG images being displayed incompletely in Gmail.
Mail Page Cloud now automatically converts all SVG images to PNG images when sending them as mail.

...

Resize images

Images that are included as attachments on a Confluence page are automatically scaled down by Mail Page Cloud when they are sent in an email. This allows the display in the mail to better match the display on the Confluence page. In addition, the mail is sent faster and the mails have a smaller size.

In addition, a maximum image width can be configured for all images in the mail, so that images without an explicit width setting on the Confluence page are not displayed too wide in the mail.
