Hi Product Hunt! 👋 I built DuplexReady after a genuinely frustrating experience — printing a 21-page report, flipping the stack, and watching the second pass come out completely scrambled. The problem: most printers don't do automatic duplex, so you print odd pages, flip, then print even pages. But if your document has an odd number of pages, the last page of the front run and the first page of the back run end up on the same sheet — throwing everything off. DuplexReady solves this in one step: upload your PDF, it auto-detects whether you need a blank page inserted, reorders all pages correctly, and gives you a ready-to-print file. No account. No install. Completely free. Would love to hear if anyone else has hit this problem — and what you think!
