can i ask what tool you use to compress?

also could you perhaps compress this image :)

Compressed!

116KB -> 8KB ( 6.9% )

Sure. I'm going to be answering @slugcat-in-gundam's ask too because they sent it at a similar time with a similar question:

I use GIMP for all image editing, besides occasional Lunapic.com usage. I did an FAQ on this on another gimmick blog a while back but I do different things here sometimes so I'll redo it anyways.

I got a higher quality version of your picture so the compression will be more noticable:

All the compression done on this blog favors aesthetics over functions, which is why there's extreme dithering on everything: dithering isn't really something that's used at all anymore but I like how it looks.

The main process is really just scaling the image down with linear interpolation to something between 64-256 pixels on the short side, and using Gimp's feature of letting you clamp an image to indexed colors, specifically with Floyd-Steinberg dithering on. If there isn't dithering, the picture will look like this:

Then I just check the sizes they export at and post the image and that's it.

If I want to make the image comically small and impossible to discern, I'll keep it as a jpeg and turn the quality way down at a tiny size:

Which will end up looking like this.

There are other techniques used sometimes, mainly on the #win98 pictures and #gba pictures.

With the win98 pictures, I scale them down to 320x240 or 160x120 every time and clamp the colors to the windows base palette, usually saturating the image before since the dithering doesn't look great otherwise. Look how this picture looks without vs with extra saturated colors:

I forgot to mention before so I'm just jamming it here, but I'll also replace text in the font 3x3 mono if it's too small to be readable to keep the image legible sometimes. You'll notice this being done with fine print and watermarks sometimes:

Here's the runthrough of that:

Lastly, with the GBA pictures, it's about the same process but I just clamp the colors down to a number that the dithering is noticeable while the image is at the gba resolution. I never noticed until making this tutorial, but there's a positioned option for dithering too which I'll probably start using for these gba posts.

That's about it. Here's the big version of the image you sent by the way:

Hello friend.

Drew this skull yesterday as a cool down drawing in Procreate, and today I went back to it, to push it more towards to what I want.

I have color processed it in Affinity Designer, and then exported it from there as gifs using the websafe palette, using 16 colors as a personal goal.

After having spent a few weeks on researching, I enjoyed making these as a proof of what I am currently looking for in my design: a lower density in detail, overall.

And I am looking for a pixelated look, like the ones above.

Yesterday, I was annoyed with how limited Photoshop for iPads is in terms of how much control I have over image compression during export and filetypes to export to (even had a few more caustic words for that), but today I realized that I can make do with Affinity Designer. It is a long shot away from the control I am used to, while the latter is also really far away from, say, ImageMagick’s capabilities (which I will test more when having a command line in front of me again). I obviously use what I have, but you won’t see me glorifying a make-do much.

I have a tendency to make drawings face to the left; that way, they seem to be facing me, like someone in front of me, if that makes sense to you. I flipped the skull for a couple of socials, added the first word that came to my mind, as sort of double-homage to both White Wolf RPGs and @plastiboo

Enjoy this image compression of which we see so very few. This looks like a lot of fun coming my way.

rendering time🔥🔥🔥

also really important question— how do i stop my ipad from compressing my photos??? like the quality in this sc is so bad 😭 every time i save a drawing, it ends up VERY compressed… help :’)

Just a general FYI. Tumblr's compression makes some of the images posted here appear in lower resolution than they actually are unless you enlarge them (I'm sure 99% of you knew this already ofc). Most of the images I source are in very high resolution.

If you're interested in a picture's finer details, try clicking on the image itself and pinch zoom (if you're on mobile). Some of the text descriptions from the artists are annoyingly hard to read otherwise.

Second FYI, some images I post *may actually* be in low resolution. I always look for the highest resolution I can find but some are just unfortunately low res.
