Illustrator designs look blurry on Social media!! Please help

[Mohamed_Elhosarie]

When i want to rasterize my illustrator design in Photoshop and upload the photo on Facebook,for example, it looks very blurry. I changed dpi and resolution and tried to solve this problem for days but nothing happened.

here is an example 

so how to make my design looks good like other designs i see in Facebook knowing that there are amazing designs on this t-shirt mockup on web so i guess the problem is not in it

Thanks in advance : )

PPI (not DPI) is irrelevant. What matters is compression settings are total number of pixels. Facebook applies its own JPEG compression to images you upload. Meaning often there is nothing you can do, it’s just a function of Facebook sucking at everything.

Thanks for reply.

i upload my design to instgram and twitter too and i have the same result too but when i upload other designs which i downloaded or upload the jpg pic which came with this t-shirt mockup,they look very good. i do not know why?!

The color red works particularly bad with JPEG compression.

Thanks for reply.

i tried some other colors now after i saw your reply and the only color that worked is white but other colors were bad.

is there any way to make red color good on FB or instgram because 90% of  my design is red?

Blurry images of the photographic type work best in JPEG. That's how the alogrithm was meant to be.

And when you are doing the same it looks like what?

It's just that: if it looks fine after exporting from Illustrator, then it's fine. Everything else is within Facebook's domain. We don't know what they are doing. You might want to ask some Social Media experts about how to optimize files for Facebook and most probably you'll be getting 5 different answers when asking 4 people.
