Microsoft Publisher to WebP converter

• Microsoft Publisher pages are laid out by our office engine and rendered to WebP by our image engine, one image per page; publications with several pages download as a ZIP.
• EXIF, color profiles, layers, animation frames, and camera metadata may be stripped unless the destination requires minimal metadata.
• Transparency stays for PNG and WebP but is filled with the selected background for JPEG, BMP, PDF, and other opaque targets.
• Fonts missing on the server are substituted before rendering, so text can wrap differently from the original file.
• SVG input is rasterized at the requested dimensions or DPI, producing pixels rather than editable vector paths.
• Server-only codecs or PDF rendering are used when browsers cannot safely handle the pair.

We converted our Microsoft Publisher sample (158 KB) with Office engine → Image engine on 2026-10-20. It took 2.5 s and produced a 339 KB WebP file, 2.1× larger than the input. The engine raised 4 warnings, listed below.

• △Fonts that are not installed on our servers are replaced with substitutes, so text can wrap differently from Publisher.
• △Text that flows between linked frames can overrun its box on multi-column pages; check each page before printing.
• △PDF pages rendered as images; selectable text is not preserved.
• △2 pages written as one WEBP each inside a ZIP.

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=webp.

curl -X POST https://filetypeconverters.com/api/v1/convert \
  -H "Authorization: Bearer $FTC_API_KEY" \
  -F "file=@input.pub" -F "from=pub" -F "to=webp" \
  -F 'options={"width":0}' \
  --output output.webp
