How do I prevent image quality from degrading over time on Confluence pages?

[Courtney Griffitts]

Hi!

I seem to have a problem with images (specifically .png files) becoming blurry over time in Confluence pages. 

I take them, they look sharp, I attach them to the page, they still look sharp, I use the border macro and publish them and they look fine. Then, when I revisit those Confluence pages a few months later the screenshots are now blurry. 

Is there a way to prevent this and keep the images sharp over time?

Thanks!

Hi @Courtney Griffitts 

I was all set to reply this is something cloud related and probably some bandwidth saving mechanism, but I see you are on Data Center. 

I would still suspect this isn't a Confluence thing but more of something on your network caching images at a lower resolution to "improve performance" I would talk with your IT team to see what is happening. 

Before bothering the IT folks, it could be something with your computer or browser. You can do the usual troubleshooting of trying a different browser, clearing cache. incognito modes, a different computer. etc.  This may help narrow it down to your environment vs the network/server environment.  If you do need to bring it up with IT, do so bearing gifts, snacks usually work.

Would add to that that I've never seen image quality degradation on Confluence, and I've seen pages 10 and more years old -- as long as we're really talking about on-premise, and not cloud.

So snacks is a good tip, sounds a bit tricky to figure out.

Edit.: If this is happening to others and not just you, check with your Confluence admins if they know what's going on. I'm thinking they could be running their own stuff to reduce image resolution for old attachments to save up on storage. That'd at least make some sense and explain why that would be happening.

Even though it's a rather crude and cheap way to save up storage it's at least got some logic to it I guess. I'd still suspect virtually anything else other than Confluence though, starting with browser.
