No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

You would like it if you had slow internet, or you hosted a website.
My website turned 5MB images into 100KB images using webp. My website now loads instantly, saves you bandwidth, and me costs!
Wait really? Are they that much more efficient?
Yep! Not least of all, GIF & JPEG are over 30 year old formats and WebP is about a decade old. So there's at least 20 years of advancement there
JPEG-XL has been out for three years, and is better and more efficient than any other image format on the market. Google just has been insisting on keeping them off the web because they want to push WebP instead.
That means absolutely nothing. We went to the moon with hardware that had ram in kilobytes. Today you need a supercomputer from the 70s to run the add of a Web page.
Progress is not linear. C is still used everywhere while some other languages didn't live a tenth of its age. New is not always better.
The reasons for this is that computing power is cheap but developers are expensive.
Yeah for sure, new is not always better.
Though for compressed media file formats, that pretty much has been the correlation for a while (though obviously there's many different conflicting qualities that can make a file format "good" for various purposes)
Take video for example: MPEG2 came along and MPEG quickly became uncommon within a couple of years. MPEG4 displaced MPEG2 due to being more efficient. DivX/AVC replaced that for the same reasons and HVEC/VP9 replaced that. We've got AV1 coming now that looks to have beaten h.266/VVC to the punch, but it's still a fairly linear progression of improvement.
Given all that it's kind of mad we've not seen the same level of iteration on image file formats, but that's almost entirely down to browser wars and having to pick lowest common denominators. JPEG2000 might have taken off if it wasn't for the fact only Apple ever implemented it in a browser—it was definitely a technically better format.
It's due to the maths behind. Special algebra is used for video compression, and a discovery has been made something like 15 years ago that allows a better video compression. It fueled technical progresses of the last years.
For images, we basically hit the wall quite some time ago. The new technologies are more about engineering improvement than math improvement.
Then there is the technical environment. It doesn't matter if your technology is a bit better than the old one because the cost to change the whole technical environment is insane. That's why ipv4 is still there for example. Changing everything for a new technology to be used is a long, costly and painful progress. But this is something only developpers can't cope with, because the development culture is painfully ignorant of industry constraints and time lines.
Lol I still don't really understand ipv6 and I work in IT. Ipv4 is so much easier and nicer to work with
I wouldn't say that. Maybe youtube uses it by default (I don't know, though) but a lot of other sites still use H264.
And I don't see AV1 even on the horizon.
A couple of years ago (2?) I tried converting some of my huge H264 video files to AV1 with then up to date ffmpeg. It was horrendously slow. I don't remember the numbers but I'm pretty sure it was progressing much slower than the clock.
Huh, TIL!
Yes.
Would you like to explain why you say no?
Because you're implying that it's 50x more efficient than jpeg, it's not. For similar visual quality of images webp will on average produce a ~30% smaller file.
You shut someone down without informing or educating them on a text based discussion centric community with an academic stick up its ass. A one word response to a complex technical question is terrible etiquette in this sort of social environment.
Next time lead with the why instead of a one word "no". This is a discussion forum, nobody knows who you are and certainly nobody is taking your word as truth if you don't provide evidence.
Bruh..
5mb to 100kb is not a typical result, so I would imagine that you are comparing apples to oranges (e.g. a very high quality jpeg vs a low quality webp)
