    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.

      PNG started out as ZIP(BMP) and hasn’t gotten that much better. Use JPEG. The pixels you lose are not worth crying about

        Or they could just compression for their PNGs. PNG is a lossless format so they’ll only lose a fraction of a second during creation.

        I use 4k because I like seeing a lot of stuff at the same time in good quality.
        I make screenshots of my whole screen to share all the stuff in the highest detail.
        Using jpeg would result in literally unreadable pictures.

        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.

          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

            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):

                convert file_example_TIFF_10MB.tiff -quality 9 test.png
                
              • JPG Encoding, 99% quality (=quality 99):

                convert file_example_TIFF_10MB.tiff -quality 99 test.jpg
                

              Final file size comparison:

              9.7M Sep  5 13:21 file_example_TIFF_10MB.tiff
              1.7M Sep  5 13:22 test.jpg
              2.5M Sep  5 13:22 test.png
              

              PNG is significantly larger, and difference in quality between them is negligible

                png - jpg

                156K Sep  5 23:06 Screenshot_20240905_230459.jpg
                137K Sep  5 23:05 Screenshot_20240905_230459.png
                

                jpg with 80% compression, via krita.

                As B0rax said, for screenshots, png is better - it can represent line graphics and text more efficiently.

                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.

          But you literally started this thread because it’s a problem. And then you spent more time defending your bad choice on a Lemmy discussion than you will ever save in your entire life decompressing PNGs.

          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 intead.

            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.
