I am using png. Level 0 compression tho and in 4k (3840*2160), sometimes even 4k + 2*1440p (2560*1440), but it’s already too large with just my main 4k monitor.
why though? The graphics represented in the screen are already squashed and scaled, so you wouldn’t be preserving their quality in any case. If you’re worried about text, JPEG should still be able to handle it under high quality settings
Dude. Did you even read what I wrote? PNG is bad for photos. Your example is a photo.
Go ahead and try the same with a screenshot with text and menus showing.
Because it was never a problem. It’s a little bit faster for encoding and decoding, and no service ever had problems with the file size. Especially not my selfhosted stuff. Every service, except discord. As I now have resorted to using Vencord or just uploading most media to Nextcloud, I don’t have that many issues with it anymore, anyway.

On the other hand, the time spent uploading/downloading much smaller files probably more than makes up for that, although even that difference might get pretty small with modern internet connections.
Yes. But in theory it’s still a performance hit, and as I have enough local storage (and typically use services with high limits), and I’m too lazy to change grims config just for discord, I never changed it and used Vencord instead.
Because even though it saves over 29 MB, it also takes more than 20 times as long. And that’s just on my laptop, 1920x1080 + 2*1680x1050. On my PC it’s even worse.
I have thousands of GB of high speed storage, Gigabit internet, but only a Ryzen 5 2600 and a i5-1145G7.

PNG started out as ZIP(BMP) and hasn’t gotten that much better. Use JPEG. The pixels you lose are not worth crying about
JPEG for graphics like screenshots is not very efficient. For stuff like that, png is simply superior. (But not with compression 0)
PNG is not good for photos though.

We can ask the same the other way around: why do you want to use jpg if it results in a bigger size and worse quality than png?
But that’s patently untrue: take this 10 MB example TIFF file as an example.
PNG Compression, max compress (=quality 9):
JPG Encoding, 99% quality (=quality 99):
Final file size comparison:
PNG is significantly larger, and difference in quality between them is negligible

png - jpg
jpg with 80% compression, via krita.
As B0rax said, for screenshots, png is better - it can represent line graphics and text more efficiently.
Why 0 compression?
Because it was never a problem. It’s a little bit faster for encoding and decoding, and no service ever had problems with the file size. Especially not my selfhosted stuff.

You know PNG is lossless compression right?
Yes. But in theory it’s still a performance hit, and as I have enough local storage (and typically use services with high limits), and I’m too lazy to change grims config just for discord, I never changed it and used Vencord instead.
Why do you think it’s a performance hit?
Because even though it saves over 29 MB, it also takes more than 20 times as long. And that’s just on my laptop, 1920x1080 + 2*1680x1050. On my PC it’s even worse.

What about compression level 1 instead of 9?
