PUB → PNG lays the publication out as pages and photographs each one, so a flyer becomes an image you can post or email to people who would never open a .pub attachment.
From real runs
| Element | Result | What happens |
|---|---|---|
| One image per page | Kept | The two-page brochure came back as sample-page-1.png and sample-page-2.png in one ZIP; a single-page poster came back as a bare PNG with no archive. |
| Pixel size | Changed | Pages render at 144 DPI by default: A4 landscape became 1684 × 1191 pixels and a Letter landscape poster 1584 × 1224. Set dpi to 300 for print-quality images (3300 × 2550 for that poster). |
| Colours, panels and photos | Kept | The brochure's lilac side panels, navy title bars and gallery photos rendered in the PNGs exactly as they appeared in the PDF step. |
| Text | Changed | Words become pixels. Nobody can copy a phone number or search the image, and screen readers get nothing, so put the key details in the post or email body too. |
| Layout problems | Changed | Whatever went wrong in the page layout is baked into the picture: text that runs under clip-art or past the edge of a frame shows the same way in the PNG. |
| Typefaces | Changed | Substitute fonts are drawn into the image, so a headline set in a decorative face shows in Noto or Liberation and may sit on two lines instead of one. |
| Background | Changed | Pages are opaque with a white paper colour; there is no transparent version of a Publisher page. |

We converted our Microsoft Publisher sample (158 KB) with Office engine → Image engine on 2026-10-20. It took 2.7 s and produced a 890 KB PNG file, 5.6× larger than the input. The engine raised 4 warnings, listed below.

LibreOffice and pdftoppm
soffice --headless --convert-to pdf flyer.pub && pdftoppm -png -r 144 flyer.pdf pageCalling soffice --convert-to png directly only writes the first page, at 96 DPI, so go through PDF for multi-page files.
The HTTP API and the MCP server run the exact engine this page uses (Office engine → Image engine); the response carries the same warnings the web converter shows. Check support first with GET /api/v1/pairs?from=pub&to=png.

Neither site accepts .pub files. Convert to PNG, then upload the page image; for a multi-page newsletter, use max_pages 1 to get just the front page.
Your publication has more than one page and each page is its own PNG. The ZIP keeps them together and in order; open it and pick the pages you need.
At the default 144 DPI it is fine on screen but soft on paper. Set dpi to 300 for a print-sized image, or print the PDF version, which keeps text as vector outlines.
