Goodreads image file preferences

[Robert]

Can't seem to find much on this, but if I am making original scans from book-in-hand, what are the file preferences for what we upload?

• JPEG or GIF?
• what DPI?
• what image dimensions?
• overall file size limit?

As I start scanning in some of these, my particular side ones to have them be as optimal as possible. I'm sure goodreads will accept a range of files, but given a choice what is most preferred?

Most of the time Goodreads will resample your uploaded covers ANYWAY so whatever you start with will be altered even if you send it at the correct dpi & dimensions.

This cover of mine was resampled down to a JPG compression level of 81. 81! Who uses 81? Good demo of compression artifacts.

Keep a copy of the old covers that you are replacing.
Just try a few, see what happens.
Don't use GIF.

Thanks, banjomike!

It's less replacing covers as creating ones that aren't there. For a few it's a matter of alternate covers, which I've read up on the when/how of that.

GR resampling engine has certainly done a number on quite a few of my scans over the last few months as well. They start out looking lovely and end up on the book page looking jagged and artefact ridden.
