If you want to save the changes, you are creating a modified PDF file. If you don’t want to save the changes, don’t save them when you close the editor (a lot of browsers could do this, aside from open PDF editors). There are ways to overwrite file changes too, to reset files to their original.

If you are concerned for the original, use backup copies.

Thanks, I’ll look into it. I tend to avoid messing with the local app folders which are often hidden and can be break if you change something.

I’d like a browser that can sync those things with a local folder that I can sync/backup however I want, no account required. Does anyone know of such a thing?
