Winner gets noting at all, losers gets maybe some knowledge in how to make a high quality picture at low picture size.

dumb nig
the goal was to make it smaller, not bigger
Like I thought. This competition is pointless, since Jow Forums recompresses uploaded JPEGs.
Uploaded size: 4,905 bytes
Served size: 8,720 bytes
Here's the originally uploaded JPEG: my.mixtape.moe
Btw what image hosting service should I use now that mixtape.moe is closing its gates?
x0.at
>no webp
>no heif
did I win?
Thanks, user. Any idea why they use an Austrian domain?
Don't forget FLIF. I think its ability to fuck up the quality with an unlimited quality parameter is unrivaled.
No idea about the domain, but it accepts every filetype. And auto deletes after half a year or so. Pretty based.
Tried again with only 1 cpu thread used.
Here are the theoretical winning strategies:
Case 1: The picture must have resembles with the original
Idea: Compress all of the image information I to one Pixel, spread it to the required size
Alg: Find average color (just add rgb values to three variables and divide through hide×width, now create image in required size comprised of only that color, fill it with that color; now test which file format supports the best compression for this. Done.
Case 2: The picture doesn't need to resemble the original
Idea: Compress image to 0 pixels, then resize it to required size
Alg: create black (or maybe white) image in requested size and test which file format creates the smallest file. Done.
fuck, I don't think I can make this smaller
script used btw:
mkdir out
for f in *.{png,jpg};
do ffmpeg -loop 1 -i "$f" -filter:v hqdn3d=256.0:256.0:256.0:256.0 -c:v libvpx -qmin 63 -qmax 63 -quality best -cpu-used 0 -t 1 -r 1 "out/${f%.*}.webm"; done
this might be it boys, 2,092 bytes
why is the uploaded image ~800 bytes heavier?
Did you use the SJW libturbo library?
