Often while scanning music, I end up with somewhat crooked pages. It's not bad, but it's also not great. Does anyone on here straighten their music after scanning? If so, what programs do you use? Does anyone know of programs that will automatically straighten slightly rotated pages in a pdf? Thanks.

If you have and Android or Apple device, try Clearscanner. It does a fantastic job at capturing, cropping (with your control), stretching it to fill a rectangle even if the photo is distorted and whitening to a perfect B&W image.
You can scan as many pages at the time as you need and creates a pdf that you can the share.
I've tried many similar apps but this one is my favorite.
