Free online PUB to PNG converter

Source format: pub

PUB is a Microsoft Publisher document format used for desktop publishing. It is commonly created with Microsoft Publisher on Windows and is used for newsletters, flyers, brochures, business cards, and other layout-heavy print documents. A .pub file can contain text, images, shapes, page layouts, and print settings, but it is not as widely supported as more common document formats.

Target format: png

PNG is a widely supported raster image format known for lossless compression and transparency support. It is ideal for screenshots, web graphics, logos, and page previews where preserving sharp edges and text clarity matters. PNG is easy to open on almost any device and is often used when you need a single-page visual export rather than an editable document.

How to convert pub to png

The best method depends on whether you need a single page image or multiple PNG files for a multi-page publication.

1. Open the PUB file in Microsoft Publisher if you have it installed.
2. Go to File → Save As or File → Export.
3. If your version supports image export directly, choose PNG or another image-based output option.
4. If direct PNG export is not available, save or export the publication as PDF.
5. Open the PDF in a tool that can render pages to images, such as ImageMagick, GIMP, or LibreOffice Draw.
6. Export each page as PNG.

Example command-line conversion from PDF to PNG with ImageMagick:

magick -density 300 input.pdf output.png

If you do not have Microsoft Publisher, you can use a free conversion option on 101convert.com without installing software.

Quality and compatibility notes

PNG is a flat image format, so the result will not remain editable like the original PUB file. Text, shapes, and layout become pixels. For best quality, export at a high resolution such as 300 DPI or higher, especially for print documents.

Multi-page PUB files usually produce one PNG per page, not a single combined image. If the publication uses fonts that are missing on the conversion system, text may reflow or render differently. Complex Publisher effects, linked images, or print-specific features may also look slightly different after conversion.

For web use, PNG is excellent when you need crisp text and transparency. For very large pages or photo-heavy publications, the PNG files may become quite large.
