PDF Comparison App
Why?
So this app is a basic PDF comparison, I was tired of reviewing drawings and not being able to spot minor differences between one print and the other. So I ended up making a comparison tool.
Granted, lots of pdf reader apps have this feature, but some of those are sketchier or not as precise. They might even work better for your use case, so don't ignore that feature.
In this case, this app checks pixel to pixel, compares both files, PDFs must have only 1 page (maybe feature incoming, idk). So, this is how it looks:
It's pretty much straightforward, just drag and drop one pdf, then the other, then click compare.
It will generate an image that will be loaded on the page, so... You can right click and download the image, or you can right click and open it on a new tab, or any way you want to work with an image. (Right click is a wonderful thing.)
Now that the instructions have been put out there:
