PPT vs TIFF
Um comparativo detalhado de PowerPoint Presentation (Legacy) e TIFF Image — tamanho de arquivo, qualidade, compatibilidade e qual escolher de acordo com seu fluxo de trabalho.
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 os arquivos PPTTIFF Image
Raster & Vector ImagesTIFF is a flexible, high-quality image format widely used in publishing, printing, and professional photography. It supports multiple compression methods and color spaces including CMYK.
Sobre os arquivos TIFFComparativo de vantagens
PPT Vantagens
- 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.
TIFF Vantagens
- Lossless by default — no generation loss on successive edits and saves.
- Supports any bit depth (1 to 32 bits per channel), any color model, any number of channels.
- Extensible tag system means vendor-specific data survives alongside standard tags.
- Multi-page containers are perfect for scanned documents, faxes, and DICOM-like stacks.
- Industry-standard for archival, museums, scientific imaging, and high-end print prepress.
Limitações
PPT Limitações
- 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.
TIFF Limitações
- File sizes are huge compared to JPEG/WebP/AVIF — often 10-30× larger.
- Not a web format — no browser displays TIFF natively.
- Ambiguous spec areas mean some TIFFs only open correctly in the tool that created them.
- Weak animation support — designed for still imagery.

Perguntas frequentes
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.
