This viewer supports both modern and legacy PowerPoint formats:
PPTX is the default PowerPoint format introduced with Microsoft Office 2007. Under the hood, a .pptx file is a ZIP archive containing XML files for slides, layouts and themes plus the embedded media - you can even peek inside one with our ZIP Viewer. This open XML structure is what allows this tool to read your slides directly in the browser, with no PowerPoint installation required.
It is one of the three core Office Open XML formats, alongside DOCX for Word documents and XLSX for spreadsheets - and we have a free DOCX Viewer and Excel Viewer for those too. If you receive a presentation exported as PDF instead, open it with our PDF Viewer, or browse the complete collection of free online file viewers.
Just drop your file into this free online PowerPoint viewer - no installation, account or Microsoft Office license is needed. The presentation opens directly in your browser with slide thumbnails, slideshow navigation and speaker notes. It works on Windows, Mac, Linux, Android and iOS.
This viewer supports both modern formats (PPTX, PPSX - PowerPoint 2007+) and legacy formats (PPT, PPS - PowerPoint 97-2003). Modern formats provide the best viewing experience with full feature support.
Yes, your presentations are completely secure. All file processing happens locally in your browser using JavaScript. Your files are never uploaded to any server, ensuring complete privacy for potentially sensitive business presentations and documents.
PPTX files (modern format) are fully supported with slide thumbnails, speaker notes and rich metadata. PPT files (legacy binary format) have limited support - we can extract text content and basic information, but some advanced features may not be available. For the best experience, consider converting PPT files to PPTX using Microsoft PowerPoint or LibreOffice.
This viewer displays static slide content - animations, transitions, videos and audio are not supported. It is designed for quickly previewing slide content, not for full presentation playback. For full animation support, use Microsoft PowerPoint or Google Slides.
The viewer supports files up to 50MB. Larger files may cause performance issues in your browser due to memory limitations. For very large presentations with many images, consider splitting them into smaller files or using a desktop application.
Yes! After loading a presentation, click "Export Slides as Images" to download a ZIP file containing each slide as a separate PNG image. This is useful for creating handouts or sharing slides on social media. You can then shrink them with our Image Resizer, reduce file size with the PNG Compressor or turn them back into a document with PNG to PDF.
Yes, if your PPTX presentation contains speaker notes, they will be displayed below the current slide in Slideshow mode. Note that speaker notes extraction is limited for legacy PPT files.
