This is a feature of your browser, not the app. I suggest using something like https://evercoder.github.io/clipboard-inspector/ to see what your browser copied.

Okay interesting. Looks like it is copied as "Blob URL" and not all other apps support reading that.

Blob URLs are not accessible to sites other than the one they originated from so this feels like a Chrome issue.

When I copy image from Chrome on macOS in an encrypted room and paste it into the site above I get the actual image/png and not just the blob URL text/html entity

The actual image/png is what other sites should be using rather than the text/html - can you confirm if you're seeing both entries in the clipboard @v411e

I want to work on this issue please assign it to me

@lalitkumawat1m this is an upstream issue, so not an issue with Element Web/Desktop but either with https://github.com/chromium/chromium or MS Word and/or Thunderbird

Yes, can confirm. This is Copied from Element Desktop and pasted in Chrome

[v411e]

But I just tried it using Element Web in Firefox and it was the exact same problem. So I guess it is not just a Chrome Issue then?

Copied from Element Web in Firefox, pasted in Thunderbird/Microsoft Word:

No, as you have shown that the image/png data is visible there, the problem is with the app pasting using text/html instead of image/png - the former they cannot parse due to blob. There is nothing we can do here, we cannot not use blob URIs due to end-to-end encryption, there's no actual URL which represents the media given its encrypted. It is probably MS Word & Thunderbird trying to be clever around "rich" pasting, but getting it wrong when they can't load the blob.

Ah makes sense, thank you for explaining
