PowerPoint to PDF Formatting Limits Explained
PowerPoint to PDF rebuilds every slide from its underlying XML structure rather than taking a screenshot of each one. That keeps the output text real and searchable, and colors matched to the deck's actual theme, but it means fidelity is best-effort rather than a pixel-perfect copy of what PowerPoint itself would export. This guide explains what carries over and what commonly does not.

What is preserved
- Text content, including individual run-level bold, italic, size, and color formatting within a text box.
- The presentation's real theme colors, resolved through the slide, its layout, its master, and the theme file.
- Basic shapes — rectangles, ellipses, and lines — with their fill color and position.
- Grouped objects and shape rotation, positioned to match the original slide.
- Embedded JPG and PNG images, placed at their original position and size.
- Slide backgrounds, including colors resolved from the layout or master when the slide itself does not set one.
What is best-effort or unsupported
Because the PDF is rebuilt from the slide's structure rather than rendered pixel-for-pixel like PowerPoint's own PDF export, a number of things do not carry over exactly.
- Animations, slide transitions, and embedded video or audio are not supported — a PDF page is static.
- SmartArt, charts, and complex diagrams are not rendered.
- Rounded rectangles are drawn as plain rectangles rather than with rounded corners.
- Exact custom fonts are not embedded — text is drawn with a standard font family chosen to roughly match the original (serif, monospace, or sans-serif).
- Bullet glyphs defined only at the slide layout or master level (rather than on the paragraph itself) may not appear, even though the bulleted text content is preserved.
- Image formats other than JPG and PNG (for example WMF or GIF) are replaced with a small "[image not supported]" placeholder rather than failing the whole conversion.
- Gradients, shadows, and other advanced fill or shape effects are not reproduced.
PowerPoint to PDF Formatting Limits FAQ
- Will animations or transitions appear in the PDF?
- No. A PDF page is static, so animations, build order, and slide transitions are not part of the output — the final state of each slide's content is what appears.
- Are charts and SmartArt converted?
- No. Charts, SmartArt, and similar complex diagram objects are not currently rendered.
- Will my exact fonts be used?
- No. Custom fonts are not embedded — text is drawn using a standard font family chosen to approximate the original (serif, monospace, or sans-serif) based on the font name in the presentation.
- What happens to unsupported images?
- Image formats other than JPG and PNG (for example WMF, EMF, GIF, TIFF, or BMP) show as a small "[image not supported]" placeholder box instead of the image, so the rest of the slide still converts.
- Are rounded rectangles preserved?
- They are drawn as plain, square-cornered rectangles with the correct fill color and position — the rounded corners themselves are not reproduced.
