Are there any websites where you can design a book cover? For free w/o paying fo it?? Ask me for details on the book if you want to help me out w/ the name of it or to know more about it
I don't think there are any.
Designing book covers requires a very specific format. You need to use the proper extension, size, bleeding, etc...
For example, this is what my publisher requires for cover designing:
TIFF (.tif) file format CMYK colorspace 300-dpi resolution Match the dimension of the final trim size, plus an 1/8" bleed on the top, right, and bottom sides (I.e., a cover for a 6" x 9" book would need to be submitted at 6.125" x 9.25")
If you don't know how to do all that, I strongly recommend you hire a graphic designer to do the job for you. Just so you know, most publishers do have their own cover designers who can create your book cover.
