It's because of the limited bandwidth cell phone users usually have.
When posting from a mobile device, we assume you are mobile as in moving through a city
or woods or whatever, where your data plan is the limiting factor.

that's your own fault for trying to see a 5760x2880px 4mb photo on a shitty dialup consumer cellular 2010s phone

>>109479316
I hope you illiterate retard realize that mobile users are the ones affected in this case, and that you will always be able to access some desktop website from a phone.

>>109479408
Sure, that's what I assumed. But why give it such shit quality? It went from 1.4MB PNG to 76KB JPG LMAO

>>109479434
The orignal image wasn't posted by me.
Also, you can still retrieve the original one on desktop. It will show you the JPG only while browsing on a mobile browser.

>>109479286
it's common on /v/ too.
If it was up to me, I'd convert these images to 256-color static GIFs. Phoneposters need correction.

Here's an example of how this doesn't happen in other boards

yes, but seeing a thread or posting with a m.jpg pic is reason enough to hide it, usually.

>>109479690
You completely missed the point of this thread. Here's a hint: images are not posted with m.jpg.

phoneposters save the mobile versions of the pics and later use them in their own postings
absolutely rebarbative

don't want mobile versions of pics? use a desktop user agent. or one of the 4chan apps.
they are a remnant from 10+ years ago or whatever, when mobile internet was still a pita and relatively slow.

>>109480122
>Also, despite “high resolution” the screens are smaller
you still can't read small the text from the OP in a smaller screen if the image is compressed to hell, you absolute retard.
4chan could easily pass that image through optipng to save some bandwidth

>>109480680
>phoneposters save
no one talked about "saving" anything ITT.

>use a desktop user agent
if you knew anything about tech or were competent, you would know or learn that your mobile browser can do that.

this isn't the thumbnail, this is the modded image, you moron. thumbnails have different naming.

>it's you not the website
it's the website, retard. go check by yourself.

who cares

every site is doing this btw downgrading image/video quality because of dram/drive shortage. even youtube charges you money for actual 1080p.

>>109479408
>It's because of the limited bandwidth cell phone users usually have.
This feature is a relic from when most people had data caps, it's not necessary anymore and the only reason it's still around is because this site never gets any updates that aren't harder captchas or more fingerprinting spyware. It's not an issue anymore nowadays with unlimited data unless you live in some shithole country.

Jesus fucking christ we hashed this all out when it was originally implemented when they started using Cloudflare for CDN…

Holy fucking shit man, so 4chan will do anything EXCEPT give us WebP support. Am I understanding this correctly?

>>109484255
WebP is cancer and should not be supported.

That's not even the worst part, when you ffprobe that JPG, it's the using the baseline profile and chroma sub sampling.
I'm pretty sure most phones today can decode JPG progressive with full chroma resolution at like 100 MP/s.

There are now altchans that support webp at least. We get banned if we mention names but they are growing in numbers so it's not as hard to find them anymore.
Avif is pretty controversial and it does seem that Google succeeded in killing Jpeg xl. Practically speaking Webp seems like it's going to be the next thing whether people like it or not.
In my honest subjective experimentation with Webp I've found that it offer significantly better compression of Anime images compared to JPG but not in photographic images.


>Webp = 96.16% support

>Avif = 93.42% support

always upload jpg to 4chan and keep your original png.
use this for peace of mind that no anon can claim your image as theirs or that you arent the same anon who posted the original image.
also png or death.

Buy an ad Daiz.

>>109479286
>Why show the low quality version of an image to mobile users
Because mobile users are careless retards anyways that won't give a shit 99.9% of the time. Also they take up the majority of the bandwidth.
Doesn't matter if phones are marginally higher res (many aren't anyway), the screen is too small to see the detail regardless.

For what? Webp? The OPEN SOURCE image format that costs $0 in royalties? You mean that?

I'm not sure if "shilling" Webp with actual ads is even necessary desu, it's doing just fine getting adopted by a huge number of websites these days.

>>109479479
well how often are you really viewing images that really require you to zoom in and read the text and shit?
I'm guessing that if you're on mobile the UX is shitty enough that you wouldn't want to do that anyways

Can someone please spoonfeed as to what the fuck OP is on about? I've been phoneposting for years and I've never come across an "m" file. Everything I save is in og resolution (more or less, I remember a controversy about a slight compression upon uploading)
Did he figure out a new ingenious way to save a thumbnail or something? Yes, I've read through the thread.

not this this one, though. >>109486492

>>109479286
because polnis heavily monitored via api in realtime and decreases bandwidth. all the apooks went elsewhere but a few still hang around. stop phonefagging if you cant figure out open unage in new tab and delete the m and/or change .jpg to .png in the filename

4chan should serve everyone the shitty mobile versions and make the original images only viewable for 4chan pass holders

>>109484286
webp has problems beyond just having garbage compression.

I'd add support for jpeg xl before I'd bother with webp.

in fact I'm probably going to write a script where if someone uploads webp, my website converts it to a {filename}.webp.jxl.

>>109485057
The only reason webp usage is rising is because Google is telling all webmasters that their site is complete garbage and will get -100 score in Pagespeed if they don't use WebP to save 0.01kbyte in image size.

I had clients bitching at me because I used webp to get better pagespeed scores and the images ended up looking horrible, so had to revert webp conversions. If Pagespeed was not pushing Webp, adoption would still be 1% like JPEG2000 and APNG.

The effort needed to convert your own personal clips to be uploaded to this fuck ass website is for the birds.
The amount of times I converted some gameplay clip from mp4, removed audio, make sure the compression isn't fucked, choosing between webm or mp4, etc. Just to have some fags ignore it or simply don't engage because it ruins their argument and derail the thread or simply the thread dies soon after.
No small part as to why effort posting or OC died on this site.
