As soon as I upload my art to Instagram, the quality decreases. I have tried everything I can think of. I have used 1080×1080 image resolution, and larger, exported it in many different files (JPG, EPS, SVG). The quality never changes and always ends up the same.
If anyone knows how to fix this problem, it would be much appreciated!
Answer
Instagram will, just like many other social media sites, convert your image into a .jpg and then compress the living daylights out of it. They have to store huge amounts of images on their servers, and those need being paid as well. Hence, they compress as much as they can.
The only thing you can do about this is taking care that compression doesn’t hurt your image too much. In your case, it is most probably the blue / magenta contrast in a tilted shape that causes the problems. In cases like these, the .jpg artefacts really show.
Try and optimise your image as a low-quality .jpg to see what will end up on instagram. That way, you know what’s coming. A small change in colour or even cropping can make a huge difference.
