Microsoft removes Publisher from Microsoft 365 on October 1, 2026, and after that your .pub files will not open unless you have an older perpetual Publisher license (2021 or earlier). Support for those is going away too. PubKeep solves both problems: preserve your files now, and keep editing them going forward.
Save your files
PubKeep Converter bulk-converts a whole folder of .pub files into exact PDFs, page for page and font for font, so your archive is safe no matter what you move to next. The first 3 files are free.
Keep publishing
PubKeep Desktop opens your .pub files natively so you keep editing the way you always have, buy once, no subscription. It is in active development, with a founder license for early users.
Who it is for
Churches, nonprofits, schools, and small businesses that built years of newsletters, bulletins, flyers, and programs in Publisher and do not want to lose that work or relearn a complicated design tool.
