Korva: Open your old Publisher files, even after Publisher is gone

Hi Product Hunt! I'm the maker of Korva. When Microsoft announced it was retiring Publisher, I kept thinking about the people who have used it for years: church bulletins, club newsletters, school flyers, restaurant menus. All that work lives in .pub files, and almost nothing else opens them properly. The usual advice was "convert everything to PDF while you still can", which doesn't help much when next month's issue needs a new date on the cover. So I built Korva, a desktop app that feels familiar if you've used Publisher, opens your .pub files and lets you keep going. What it does today: • Opens .pub files with the layout intact: pages, master pages, pictures, text boxes, stories that flow between columns and pages, fonts and colours • Editing you'll recognise, with a ribbon, text wrap, tables, shapes, WordArt, shadows and master pages • Print-ready PDFs with crop marks and CMYK, and pictures sized sensibly, so a 12-page newsletter comes out at a few MB instead of 35 • Mail merge, labels and booklets • A Rescue Center that turns a whole folder of old .pub files into PDFs in one go • Everything runs offline on Mac, Windows and Linux. No account, nothing uploaded. The hardest part was the .pub format itself. It isn't documented, so reading the real layout meant a lot of careful work, checked page by page against Publisher's own PDFs. Big thanks to the LibreOffice people behind libmspub, whose work on the format was an invaluable map. Early users have been sending me their real newsletters, and every one of them has made Korva better. Your first project is free, and Pro is a one-time $49. No subscription. I'd love your feedback. And if you have an old .pub file that doesn't open the way you expect, please send it my way. That's exactly how Korva keeps getting better.
