Traditional raster icons (GIFs, JPGs, and even PNGs) should not be "scaled up."  Instead, the newer SVGs should be used, just as they are in the newer Confluence editor (Fabric).  This would necessitate that the Export PDF feature (maintained by the software company K15T) change the rendering of SVGs so that they remain vector-based images in the PDF rather than rasterizing them as they do today.

Does anyone (from Atlassian or otherwise) know the best way to request this of K15T and how frequently does Atlassian upgrade to the latest version of K15T's Scroll PDF Exporter?

Please kindly update. This issue makes pdf export with image actually NOT usable. The result image quality is terrible. 

Can you please give an update on this issue as it seems to be open since 2013...
And we are having issues with our documents to be sent out

I have created a clear and crisp suggestion for Atlassian Confluence team: CONFCLOUD-54983. Hope for a positive response.

Hi Manuel. I can't answer your questions. I discovered that my company has a symbol font and that I can use it for logos. Apart from that I don't know much about fonts. People from your design department should know more. And since I have nothing to do with Atlassian I don't know about their plans.

Hello Steffen. Is there a way to put in multi-colored logos into a font that is working? has atlassian planed to add quality logos? thank you for your help

@Steffen: Now I got you right, thanks for clarification and this workaround. We will give this a try!

@Jens: I think you got me wrong. I was not talking about "writing" the logo with normal letters. What I meant was creating a symbol font that exists of different symbols and/or logos instead of letters. We have such a font. Different letters correspond to different symbols. The letter "c" for example is our normal logo, other letters are for the Chinese logo or certain brand names with symbolised letters in it.

Hi! Thank you for your suggestion! Unfortunately, we cannot implement this since we do not just have letters on our logo(s) - we also have icons. We could only try to create a mix-up of background-image and the font. But this will also not look very professional since the image will still look ugly .

A background image in good quality won't work with confluence, no matter what you try. There is one workaround that works well:

• Create a font with your logo and include the logo as a "letter" from that font

This is the code we are using:

@top-right {  
/* Our logo */  
content: "c";   
font-family: OurOwnSymbolFont;  
font-size: 22px;  
}   

@font-face {    
src: url(/download/attachments/73371514/OurOwnSymbolFont.ttf);    
-fs-pdf-font-embed: embed;   
}
