Found a stat about JPEG compression that blew my mind
I was digging into image file sizes for an art showcase submission last week and read that JPEG compression can drop file size by 80% with almost no visible loss. Found it on a photography forum where a guy tested 100 different images. It made me rethink saving everything as PNG for my portfolio. Has anyone else noticed quality differences with high compression on detailed pieces?

My buddy Mark tried to save his digital paintings at 90% compression once for a game jam upload and his character's face turned into a blocky mess with weird color streaks around the eyes lol. He spent like 2 hours redoing it because he didn't keep the original PNG. I think for most stuff 80% is fine but those really detailed brush strokes get trashed fast.

Did you try cranking it even higher than 80% for those detailed pieces? I messed around with this exact thing last month when I was uploading some old fan art to a free hosting site. I had this one drawing with a ton of small, sharp textures in the background, and at 80% compression it actually looked fine on my screen. But then I tried 95% just to see what would happen, and the whole thing turned into a mess of weird color blotches and jagged edges, kind of like someone smeared paint over a broken mirror. Your buddy Mark's experience sounds exactly like what I ran into, those little brush strokes and fine details just get destroyed the second you push it past a certain point. So yeah, 80% is about the max I'd ever go for anything I actually care about.

Reminds me of what @kellygrant said about her friend Mark, because my buddy Dave did the same thing with his comic book style art. He pushed it to 95% to save space on a portfolio site and all his crosshatching turned into a blurry soup. He learned the hard way to keep a backup PNG after that mess.
