Images that are uploaded from smartphones are commonly over 4MB in size (my max upload size is set to 5MB). I just took one of these images are dumped it into ImageOptim and the size dropped to under 800KB. I can’t tell the difference when viewing the pics. [이미지] Is there any way to have somethi…

I’m very interested as well! I though though that images get resized/compressed after initial upload, so you can even allow e.g. 10MB uploads, but limit max image width/height dimensions in your Settings.

There is some support for this @zogstrip can elaborate as he has time.

There is definitely demand for further compression / pixel size limiting after upload. Imho it should be allowed to upload big files but optimize / downsize them on the server after upload based on parameters from admin config. Specifically for mobile uploads it would be beneficial to downsample t…

[이미지] Overgrow: There is definitely demand for further compression / pixel size limiting after upload. Yes. For example, for our non-commercial community it tends to become vital. Every cent counts when no one is sponsoring… How much money we spend on the server, it mostly depend on how much …

Exactly.. from my experience fast access drives (15k SAS HDD or SSD) have always been biggest factor to server operating cost.

FYI: I recently re-worked our upload pipeline, which includes auto-converting large PNGs into (very) small JPEGs. You can fine tune the quality of the JPEGs with the “png to jpg quality” site setting.

The paint point here was very large uploaded PNGs which had absolutely no business being lossless PNGs, when they could be lossy JPGs at 1/5 or less the size. For small images (1280x720 or less) it does not matter so much, but get to 1080p++ and the cost becomes .. extreme. 1,651,936 Screenshot_201…

Yeah, larger res PNG’s are way bigger than JPEG’s. I am considering removing PNG’s from the approved files list; do any smartphones use PNG as the native capture format?

Images are still too big -- how to compress further?

You shouldn’t need to worry, latest version of Discourse handles this perfectly and seamlessly. If Bad Users upload giant PNGs we auto-force-convert them as needed.
