Free online PUB to JPG converter

Source format: PUB

PUB is the file format used by Microsoft Publisher, a desktop publishing program for creating newsletters, flyers, brochures, business cards, and other page layouts. PUB files can contain text boxes, images, shapes, tables, and page formatting arranged for print or digital distribution. Because PUB is not as widely supported as common document formats, it is often converted when you need to share the content with people who do not have Publisher or when you want a simple image preview of each page.

Target format: JPG

JPG or JPEG is a widely supported raster image format. It uses lossy compression to keep file sizes relatively small, which makes it useful for web pages, email attachments, previews, and general sharing. For PUB conversion, JPG is typically used to turn each page of a publication into a separate image.

How to convert pub to jpg

The exact method depends on whether you have Microsoft Publisher installed and whether you need a quick preview or a higher-quality image output. In many cases, the most practical workflow is to export the PUB file to PDF first and then convert the PDF pages to JPG.

1. Open the .pub file in Microsoft Publisher, or upload it to the 101convert.com converter to convert it online for free without installing software.
2. If you are using Publisher, try File → Export or File → Save As and look for a PDF option. Publisher does not normally provide direct JPG export for full publications.
3. Open the resulting PDF in a tool that can export pages as images, such as Adobe Acrobat, LibreOffice Draw, or another PDF-to-image workflow.
4. Export each page as JPG. Multi-page PUB files usually become one JPG per page, such as page-1.jpg, page-2.jpg, and so on.
5. Choose an appropriate resolution before exporting. For sharper text and print-oriented previews, use a higher setting such as 300 DPI. For web sharing, a lower resolution may be enough.

Alternative desktop workflow

If you prefer command-line tools after converting PUB to PDF, ImageMagick can turn PDF pages into JPG images. For example, magick -density 300 input.pdf output.jpg can be used to generate image output at a higher resolution. This is helpful for batch conversion or when you want consistent sizing across pages.

Quality and limitations

JPG is a flat image format, so the converted file is no longer editable like the original PUB document. Text, shapes, and layout elements become part of the image. Because JPG uses lossy compression, very sharp text and thin lines may look softer than they do in Publisher, especially at low resolution or after repeated saving. For best results, export at a higher DPI and avoid unnecessary recompression.

Also keep in mind that complex PUB layouts may not render perfectly if fonts, effects, or objects are missing or not fully supported by the conversion tool. If you need to preserve the layout for printing or archiving, PDF is usually a better intermediate format. If you need editable content, keep the original PUB file or convert it to an editable document format instead.

Summary

To convert PUB to JPG, open the publication in Microsoft Publisher or use the built-in converter on 101convert.com, export or print the file to PDF if needed, and then convert each PDF page to JPG. This produces easy-to-view images that are simple to share across devices and platforms.
