Do you notice the quality of Jpegs are not very good when saving pictures with less colours?

Yes, the edges of shapes and colours look kind of smudgy compared to gifs and PNG files.

But, if you use less compression on JPEGs the picture is cleaner.

this is caused by most applications saving .jpg at 90% quality, so each time yuo save it degrade sby 10% of the last save,

compression strips away some of the colour depth, is why it pixelates.

best thing to do is save in .png eidt that then save in .jpg, when you need to make changes re-open the .png
