PPT vs WEBP
Una comparativa detallada de PowerPoint Presentation (Legacy) y WebP Image — tamaño de archivo, calidad, compatibilidad y cuál elegir según tu flujo de trabajo.
PowerPoint Presentation (Legacy)
PresentationsPPT is the legacy binary format for Microsoft PowerPoint 97-2003 presentations. Many archived presentations and templates still use this format and require conversion for modern editing.
Sobre los archivos PPTWebP Image
Raster & Vector ImagesWebP is a modern image format developed by Google that provides superior lossless and lossy compression. Files are typically 25-35% smaller than equivalent JPEG or PNG images at the same visual quality.
Sobre los archivos WEBPComparativa de ventajas
PPT Ventajas
- Universal legacy compatibility since 1987.
- Binary format loads quickly on older hardware.
- Preserves animations, transitions, and embedded media.
- Every modern presentation tool can open it.
WEBP Ventajas
- 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.
Limitaciones
PPT Limitaciones
- Deprecated since 2007 — PPTX is the recommended format.
- Animations and SmartArt often render differently outside PowerPoint 2003.
- Macro-enabled variants are a malware vector.
- Binary corruption often unrecoverable.
WEBP Limitaciones
- 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.

Preguntas frecuentes
PPT is the legacy Microsoft PowerPoint binary format used from 1987 to 2007. It shipped as part of the OLE Compound File container in PowerPoint 97-2003 and was replaced by PPTX in Office 2007. Legacy PPTs still circulate in academic and corporate archives.
PPT files open in every PowerPoint version since 1997, Google Slides (free), LibreOffice Impress (free), Apple Keynote, and most online viewers. Mobile PowerPoint apps on iOS and Android handle PPT natively.
Open the .ppt in PowerPoint and use Save As → PowerPoint Presentation (.pptx). KaijuConverter offers single-click PPT-to-PPTX conversion. LibreOffice Impress and Google Slides also convert on export. Conversion usually preserves animations and transitions.
Always PPTX for new decks. PPTX files are smaller thanks to ZIP compression, follow the ISO/IEC 29500 standard, and support every modern animation and effect. PPT is frozen since 2007 and missing most features introduced in PowerPoint 2010+.
PowerPoint's proprietary animation engine uses undocumented binary structures that LibreOffice Impress approximates imperfectly. Most basic transitions work; complex motion paths and advanced SmartArt animations often render differently. Use PPTX export for better cross-tool fidelity.
PPT can contain embedded VBA macros that may run malicious code. Modern PowerPoint blocks macros by default. For untrusted sources, open the file in Google Slides first — it strips macros and shows the slide content safely.
