- Cross-compatible with Keynote, Google Slides, LibreOffice Impress (with minor drift).
- Preserves master slides, themes, animations, notes, and embedded media.
- ISO/IEC 29500 standardized — vendor-independent on paper.
WEBP Vorteile
- Smaller file sizes than JPEG, PNG, and GIF at equivalent visual quality.
- Single format for lossy photos, lossless graphics, transparency, and animation.
- Full alpha channel support with smaller files than PNG.
- Now universally supported in all modern browsers.
- Open-source reference implementation (libwebp) by Google.
Einschränkungen
PPTX Einschränkungen
- Animations and transitions often render differently outside Microsoft PowerPoint.
- Embedded fonts and media balloon file sizes rapidly.
- Complex layouts drift subtly when round-tripped through non-Microsoft editors.
- Older .pptm macro-enabled variants are a malware vector via VBA.
WEBP Einschränkungen
- Some older software and image editors still don't read WebP natively.
- Max dimensions are 16,383 × 16,383 — lower than JPEG or PNG.
- Print workflows rarely support WebP (no CMYK, limited color management).
- Editing tools are less mature than JPEG/PNG; round-tripping can lose quality.
