Convert Publisher PUB to JPG Online

Microsoft Publisher (.pub) is the desktop publishing application included in some Microsoft Office Professional and 365 editions on Windows, used for newsletters, brochures, flyers, business cards, and church bulletins. Publisher has no native macOS, iOS, Android, or Linux client - it's Windows-only, which makes .pub files notoriously difficult to share. Recipients on Mac or mobile typically cannot open them without buying the Office Professional license and a Windows machine or VM. Converting PUB to JPG produces a universal preview that any image viewer can open.

The .pub format is proprietary, undocumented at the byte level by Microsoft, and only loosely supported by third-party tools. LibreOffice Draw can open Publisher 2003 and earlier files reasonably well via reverse-engineered importers, but later versions (Publisher 2007/2010/2013/2016/2019/365) have additional features that often fail to round-trip. The cleanest conversion path is to open the file in Publisher itself and use File > Export > Save as PDF, then run PDF-to-JPG. This converter routes through that pipeline server-side, rasterizing each page at the publication's page size.

Small businesses, churches, schools, and community organizations whose previous secretary used Publisher to create the weekly bulletin or quarterly newsletter are the typical audience. When the original .pub file is the only surviving copy and the recipient lacks Publisher, JPG-per-page is the safest universal output - works in email, web, mobile, and any document portal that accepts images. For ongoing editing migrate to Affinity Publisher (50 USD, Mac/Win, opens PUB via PDF intermediate) or Scribus (free, cross-platform, no native PUB support but excellent for new layouts).

Microsoft Publisher first shipped in 1991 as Microsoft's entry-level desktop publishing tool, aimed at home users and small businesses producing newsletters, flyers, and brochures. The .pub format is a proprietary binary specific to Windows - Microsoft never released a Mac version, and the format has no published specification. Reverse-engineered import filters exist in LibreOffice (via libmspub) but layout fidelity is imperfect. Publisher remains bundled with certain Microsoft 365 subscriptions but is being deprecated in favor of Designer and Word - making .pub conversion increasingly relevant for legacy file rescue at churches, schools, nonprofits, and small businesses.

Microsoft Publisher PUB files are the output of Office Publisher, used to create flyers, brochures, newsletters, event programmes, and marketing materials. PUB is not supported by Word, LibreOffice, or Google Docs, and opening Publisher files on macOS requires a third-party utility. Converting to JPG makes the Publisher layout fully accessible as a viewable image that works on every platform and in every application.

Small businesses and community organisations that use Microsoft Publisher for printed marketing materials - Flyers for local events, restaurant menus, charity newsletters - Need to share those designs digitally. Converting the PUB file to JPG produces page images that can be emailed, posted to social media, uploaded to a website, and sent to a print-on-demand service without the recipient needing Publisher installed.

Print shops that receive PUB files from customers but run non-Microsoft prepress systems - Including macOS-based and Linux-based setups - Convert them to JPG (or PDF) for design review and print preparation. The JPG shows exactly how the layout looks, allowing staff to check alignment, bleed, and content accuracy before committing the job to print.
