I scanned a bunch of pages that came out sideways and rotated them in the viewer so they look right but the changes never stick when I save and reopen the file. Is there a way to make the rotation permanent?
Honestly the rotate button in most viewers only changes the view, not the actual file, so it resets when you reopen. What works for me is rotating it how I want, then printing to a new PDF with Microsoft Print to PDF. That bakes the rotation in for good. I do this all the time with sideways plan scans.
I had this exact problem with sideways patient scans at work. Most viewers only rotate your display, not the file itself. What worked for me was using PDFcap. You just upload it, rotate the pages the right way round, and download the new copy. It saves the rotation permanently so it stays fixed.
Most default programmes only rotate the screen view, not the file. I usually open the file in my web browser, fix the orientation, and use the ‘print to PDF’ function to save a new copy. Avoid saving over your original scan until you know it worked. I learned this the hard way when a batch of market invoices printed completely sideways.
Had the same thing last month with some scanned receipts. Usually that means your viewer is only rotating the display, not the actual page object, so it resets on reopen. On Windows I just opened it in Microsoft Print to PDF after rotating, basically printing the rotated view back into a new PDF, and that locked it in permanently.
@sarcastic_sea the print to PDF trick is what I do too, on my old laptop it takes ages per file but the rotation always sticks. I keep a copy of the original scan as well, just in case.
@Emily.7 Same here, printing to a new PDF is a reliable workaround, especially with older laptops. Keeping the original scan untouched is wise in case the new copy loses quality or metadata.
I usually use a proper PDF editor’s Organize Pages tool, rotate the selected pages there, then Save As a new file and reopen it to check. Viewer rotation is often only a display setting, which I learned the hard way with scanned worksheets. If the editor still will not stick, I print to PDF or use OCR software that can deskew and export a fresh PDF.
Most viewers only apply rotation as a temporary display thing, it does not actually rewrite the page. You need to save the file through a tool that commits the rotation, like opening it in a proper PDF editor and using Save rather than just closing. I learned this the hard way with sideways scans too.
@Emily.7 Keeping the original is the right habit. When I have a stack of sideways scans I rotate and print them in one batch and let it run while I do other work, then compare page count on the new copy before deleting anything. On slower machines give it a few minutes per batch, it does get there.
most pdf viewers just rotate how it looks on screen they dont change the file. i use pdfarranger for scanned stuff like this rotate the pages and save and it actually sticks. not sure if its the same on mac
