don’t save as jpeg
as a former yearbook editor and designer, let me explain this further
if youre only planning on posting your art online, them please save it as .png ;this is also better for transparencies as well
please, if youre planning of printing your art, NEVER use png. it makes the quality of the image pretty shitty. use jpeg or pdf instead. and always set your work at 300dpi to get a better printing quality - this means, the images are crisper and sharper and theres no slight blurriness. i had a talk with my friend who is currently taking design, and pdf is much better to use when youre working with a bigger publishing company because it still has the layers intact, but if youre only planning on printing your stuff at staples or at some small publishing store, the jpeg is the way to go.
this has been a public service announcement
wrong wrong wrong!
From someone who has personally had to deal with the intricate bits and bytes of such file formats do NOT use JPEG for print if you want to maintain the quality of your image.
Jpeg is a LOSSY format. The JPEG stream stores a mathematical approximation of your data using a discrete cosine transformation. If you are in a situation in which you can afford to lose details in your image and want a small file size (such as for distribution on the internet) then go ahead and use jpeg. If you are in a situation that requires 1:1 pixel-sensitive details and want a the smallest possible file size then use PNG or TIFF or some other file format that does NOT impair the quality of your image.
- Want to maintain 1:1 image quality? USE TIFF OR PNG or some other lossless file format.
- Can you afford to lose image detail in favor of a smaller file size? Use JPEG or some other lossy format.
What the OP is mentioning here most likely specifically addresses that! Especially with art you want to make sure the people who see your art are getting the best possible quality image!
The “slight blurriness” that is being described is most likely an artifact of up-scaling an image using bilinear-filtering which is one of the many ways a computer calculates the in-between pixels of an image when scaling a bitmap to be larger.
Here are more details on each of the file formats I’ve seen people mention in reply to this post:
