wdym “terrible quality loss”; for one their lossless beats PNG
This depends, if your image contains a lot of flat colours (like a screenshot of a website) then PNG can actually give you smaller file sizes than lossless webp. But for most images (especially ones with compression artefacts) lossless webp gives smaller sizes.
But that’s not got anything to do with quality. That’s compression size
Lossless encoding, by definition, won’t have any quality loss.
Watch some startup “invent” a revolutionary lossless format that discards some information.
Fuuuuuck. There goes another business idea. 😂
did that ages ago
That’s the point of revolution, no?
Going back to something that was in the past, except giving it a new name and context:P
Huh? The OP literally said “their lossless beats png” and then you proceeded to talk about file size which wasn’t ever part of the conversation. The conversation was about quality.
But for most images (especially ones with compression artefacts) lossless webp gives smaller sizes.
And if you already have compression artifacts, what use is lossless?
Only time you would want it is when you are uploading comparison photos specifically showing compression artifacts created from some other compression result.
That’s a bit to niche to make it worthwhile.deleted by creator
Lossless is fine, lossy is worse than JPEG.
If someone chooses lossy they deserve whatever torture they receive.
Unfortunately most people don’t really have a choice in the matter. It’s sites like twitter that crunch images to hell and back on upload that choose for us.
Choose life don’t use webbed sites that use lossy webps
JPG-XL crying in the corner.
Sitting next to JPEG-2000
> complains about lossy format
> meme uses lossless imageAm disappoint
To be clear, webp isn’t even a lossy format. I mean, it can be, but it can also be lossless.
The posting of webps will continue until support improves.
Is webps just webp with SSL ? 😏
No, it’s a new format remember?
So TLS, maybeAh right. It should be TLS, and it may be SSL for future backward compatibility, sometimes resulting in corrupted images without warning.
Quality loss? Webp supports lossless.
So does JPEG. It doesn’t mean that people (will) use it for that.
Actually? I didnt know that. Is it used often? Any downsides ?
Practically never because it’s rubbish. The only possible use is on old precision machines that don’t support newer standards, like medical imaging.
Webp supports lossless compression. It’s even better than .PNG in that regard.
I also have rarely found it to not work. Like the only things I can think of off the top of my head is that the basic Microsoft image viewer that comes standard on Windows won’t open them and also how some websites will force an animated .gif to be saved as a webp, making it a static image. Even though I am pretty sure webp also supports animation.
JPEG also supports lossless compression.
Does it? Paint doesn’t seem to use it. Even saving something uncompressed adds artifacts that don’t exist in the raw.
You mean the Microsoft made program?
Yeah. I would imagine a better program actually has lossless compression if the format can do that. Like I mentioned initially, their own image viewer can’t even open WebP; but using the old one from XP/Vista opens them fine. 🤷♂️
And it’s more of a video format than an image format, lots of juicy attack surface
Sounds like avif
JXL is the rightful heir to the throne and none of these treasonous corporate usurpers in the court can convince me otherwise. I’ll never bow to the Webp or Avif factions. While it looks bleak, I pray the crown finds its way to the head of the true king. Long live the Jpeg bloodline!
But really, webp was pushed because it supports DRM and avif is an implementation detail turned feature afterthought just because webp adoption sucked as much as the format does. I love AV1 for video but avif isn’t fit for purpose and webp is garbo. I really wish they didn’t take jpegxl out behind the shed for no good reason… It has some awesome engineering.
AVIF is funny because they kept the worst aspects of WebP (lossy video based encoding), while removing the best (lossless mode) There was an attempt at WebP2, using AV1 and a proper lossless mode, but Google killed that off as well.
But hey, now that they’re releasing AV2 soon, we’ll eventually have an incompatible AVIF2 to deal with. Good thing they didn’t support JPEG-XL, it’d just be too confusing to have to deal with multiple formats.
16 CVE’s for libjpeg just last year: https://app.opencve.io/cve/?vendor=jpeg
Webp has both a lossy and lossless mode so the first part of this meme is lost on me
Never understood why jepgXL didn’t win out
Because Google didn’t invent it, and Google decides what does and doesn’t get added to the Internet.
Google were literally one of the three organisations who worked on the standard, and the top contributor to the reference implementation works there.
And then they killed it. It was Google pulling support in Chrome that killed JPEG-XL’s momentum.
It was the Joint Picture Experts Group that invented it, so Google had no ownership over it, unlike WebP.
Google’s stance on JPEG XL is ambiguous, as it has contributed to the format but refrained from shipping an implementation of it in its browser. Support in Chromium and Chromeweb browsers was introduced for testing April 1, 2021[29] and removed on December 9, 2022 – with support removed in version 110.[30][31]The Chrome team cited a lack of interest from the ecosystem, insufficient improvements, and a wish to focus on improving existing formats as reasons for removing JPEG XL support.[29][32][30]
It’s different people who develop and who decide.
It’s slowly marching along with the reimplementation of its reference decoder in rust. That should hopefully satisfy google and mozilla’s demands and get them to adopt it in their browsers.
I’m noticing that a lot of my memes are auto saved as webps, what can I convert these into so as to be most compatible and least likely to offend those that care about file formats?
I mean, if we’re being realistic, everything I use supports .webp now. Hell, every upload on my instance Blajåj becomes one (not Lemmy universal, as noted by SatyrSack)
Hell, every upload on Lemmy becomes one
That is something set by your instance admin. lemmy.sdf.org actually automatically converts uploaded WEBP files to PNG. It’s just up to what the admin wants.
That’s good to know! If I ever get to make an instance of anything in the Fediverse and I set it to save images (lol, fat chace), I’m setting it to either JPEG-XL or XPM.
Oh, I forgot webp supported transparency.
Guess it has something over jpg.
Jpg
It’s old, as in 1980’s, so everything supports it
I’d recommend webp
Everything supports it and it can be lossy or lossless as needed.
What? Why does this meme say it’s not compatible with anything then? Did I get trolled?
On the other hand, if you just want to make people uneasy and some even angry, you can just use and share bitmaps.
This meme is out of date.
To be fair, it’s not terrible quality loss, it’s just worse than JPEG, the main format it was trying to replace. It’s way better than GIF though.
That’s kind of terrible as JPEG is lossy af
That depends on the compression level
Not my fault that peoples pirated copy of Photoshop CS5 can’t open it.
Better to just use gimp at this point surely?
hmm, I usually just change the .webp extension to .png, and most of the time, image viewers just open it without issue.
This doesn’t change it to a png, but your image viewers recognize it as webp. You should just associate .wepb with your image viewer in the OS.
yeah, I figured as much. I guess even seeing the .webp extension bugs me so much that I can’t even stand the sight of it.

Webp can be lossy or lossless though, and what kind of shitty apps are you using that don’t support it?
