There are some free online PNG-to-SVG file converters as well as downloadable software for off-line converting. Some only handle one file at a time, but there may be some that will handle sets of files. I haven’t checked them out myself, but if you run a simple search using can a png file be converted to svg you can check out the different offerings yourself. Experiment with different converters as some may give better results than others.
A real user can’t see that time difference. And lag of network, devices etc. are way bigger than loading/serving time savings what SVG emojies gives. Lab tests shows soemthing like 20 ms benefits that are totatally theoretical.
And the most important thing: Google just doesn’t care.
No one can. Do you understand size of an emoji?Just redirecting to subdomain takes longer. Even loading up a topic without a single emoji takes longer.
Do you know how long a eye blink takes?
Again. It can be an option if you or anybody else can find SVG-only emoji library. But it can’t be opt-out. And the work to achieve speed effort, that not makes any forum faster — there is no point.
If you really don’t know how to measure speed of a site or do stress tests it is not my job to teach you. Do some googling. But if you don’t know those basics it tells why you are so sure SVG emojies make a forum faster
Try not to get off track here, making emoji SVGs is not a major priority for us until we have some real-world examples in Discourse that show us there’s a problem. We have no existing issues with “crispiness.”
Debating which method is technically best isn’t going to get much traction here (so I recommend stopping). It has to be significant enough for us to prioritize it over other work.
