Share a screenshot as a link, not as an attachment
A screenshot is only useful once somebody else has seen it. Ruyazo turns every capture into a link that opens in any browser, with no account and nothing to install at the other end, and lets you decide who may open it and for how long.
What the other person sees
A page with the picture on it and almost nothing else. No sign in, no app, no banner asking them to open it somewhere better. Adding .png to the end of the link gives them the bare file instead, which is what you want when you are pasting into something that renders images itself.
Links work in chat, in a ticket, in an email, and in anything that unfurls a URL into a preview.
Three levels, decided per upload
Unlisted is the default: the link works for anyone holding it, and nothing lists it anywhere. Public puts it on your profile if you have made one. Private means only you, while signed in.
The setting is per upload rather than per account, because the screenshot of a bug and the screenshot of a bank statement do not deserve the same treatment.
Links you can take back
A share link is a separate object pointing at the same upload. You can give it a password, an expiry date, or both, hand it to one person, and revoke that one link later without touching the original or any other link.
A share link opens a private upload too. That is how you send one file to one person without making it reachable by anyone who has the ordinary link.
