Saving a Publisher flyer or card as a JPG without Publisher

PUB files turn up when someone designs a flyer, newsletter, invitation or business card in Microsoft Publisher and sends the original instead of an export. Only Publisher on Windows opens them, and with Publisher reaching end of support in October 2026, many people now hold PUB files they cannot view. Converting to JPG gives you a picture of the design to post online, print at home or attach to an email.

The converter rebuilds the publication from the file and renders its first page only, at 150 dots per inch. A Letter-size flyer comes out 1275 × 1650 pixels, an A4 page 1240 × 1754, and a publication set up as a 3.5 × 2-inch card about 525 × 300. That works for social posts and email but is modest for printing: at a print-quality 300 pixels per inch, the Letter flyer would cover only about 4.25 × 5.5 inches.

For every page or a sharper image, convert the PUB to PDF, which keeps all pages with real text, then export the pages as JPG at up to 300 DPI. If a website or form caps the file size, compress the JPG to 200 KB.

Check the JPG before you use it

Read every line against the original; a font that isn't embedded in the PUB is replaced with a similar one, which can move line breaks.
Make sure every picture and logo appears, and that layouts with unusual effects have not shifted.
Remember that a multi-page newsletter gives you page one only in the JPG.
If the page says it couldn't open the file, it may be damaged, password-protected or from a Publisher version the converter can't read yet; try another copy.
